In-Text Citations: An Overview

In-text citations are brief, unobtrusive references that direct readers to the works-cited-list entries for the sources you consulted and, where relevant, to the location in the source being cited.

An in-text citation begins with the shortest piece of information that di­rects your reader to the entry in the works-cited list. Thus, it begins with what ever comes first in the entry: the author’s name or the title (or descrip­tion) of the work. The citation can appear in your prose or in parentheses.

Citation in prose  Naomi Baron broke new ground on the subject. Parenthetical citation At least one researcher has broken new ground on the subject (Baron). Work cited Baron, Naomi S. “Redefining Reading: The Impact of Digital Communication Media.” PMLA , vol. 128, no. 1, Jan. 2013, pp. 193–200. 

When relevant, an in-text citation also has a second component: if a specific part of a work is quoted or paraphrased and the work includes a page number, line number, time stamp, or other way to point readers to the place in the work where the information can be found, that location marker must be included in parentheses.

Parenthetical citation According to Naomi Baron, reading is “just half of literacy. The other half is writing” (194).

The author or title can also appear alongside the page number or other loca­tion marker in parentheses.

Parenthetical citation Reading is “just half of literacy. The other half is writing” (Baron 194).

All in-text references should be concise. Avoid, for instance, providing the author’s name or title of a work in both your prose and parentheses.

Citation (incorrect) According to Naomi Baron, reading is “just half of literacy. The other half is writing” (Baron 194). Citation (correct) According to Naomi Baron, reading is “just half of literacy. The other half is writing” (194).

Hello! I am a high school English teacher trying to answer a question that came up during our research unit. I can’t seem to find a definitive answer online. When using a shortened title in an in-text citation, does an ellipsis need to be included? For example, if the title was “The Problem of Poverty in America: A Historical and Cultural Analysis”, would the in-text citation be (“The Problem of Poverty in America...”) or (“The Problem of Poverty in America”)? Thank you for your time and expertise!

Your e-mail address will not be published

Laura Kiernan 12 April 2021 AT 11:04 AM

No, an ellipsis would not be used in an in-text citation. We provide extensive guidance on shortening titles in 6.10 of the new ninth edition of the MLA Handbook .

angel 10 May 2021 AT 02:05 PM

hii How to write an in text citation of an entry from encyclopedia which has an editor but no separate authors for each entry ?

William Feeler 11 May 2021 AT 01:05 PM

I see no mention of paragraph numbers for unpaginated prose or sections/lines for drama. are these practices gone?

Laura Kiernan 18 May 2021 AT 01:05 PM

This post provides a general overview of our approach to in-text citations. The complete guidelines appear in sections 6.1–6.30 of the ninth edition of the MLA Handbook .

Vonceil Park 11 May 2021 AT 01:05 PM

Dear MLA Staff, A professor at my College demands students to provide paragraph number in the in-text citation for online articles that have no page number nor paragraph number. Do we just count the paragraph number and put them in the parenthesis, for example: (para. 3)?

Laura Kiernan 18 May 2021 AT 12:05 PM

Thank you for your question. Your approach to modifying our style in accordance with your professor's instructions works, but we would suggest confirming that styling with your professor.

How to write an in text citation of an unsigned entry from a reference work?

Laura Kiernan 08 June 2021 AT 11:06 AM

If the entry was in a print work, the in-text citation would include the entry’s title or a shortened version of the entry’s title and the page number of the quotation. If the entry was in a reference work without page numbers, the in-text citation should just contain the title or shortened title of the entry.

Sethu 17 May 2021 AT 02:05 PM

For example: Can I give an in-text citation like the following: Shakespeare, in his work Hamlet, quotes: "To be or not to be" (7).

For citing commonly studied verse works, see 6.22 in the ninth edition of the MLA Handbook .

Trinity Klein 21 May 2021 AT 11:05 AM

Can you please help with proper in-text citation placement for an embedded quotation? Does the citation come immediately after the quotation or at the very end of the sentence? For example, is this correct: He asks her to take him home “in the voice of a child afraid of the dark” which comes as a shock to Scout because he has so long held a bold and rebellious reputation (372). Or should the (372) come immediately after ...dark"...? Thank you!

For more information about the placement of a parenthetical citations, see 6.43 in the ninth edition of the MLA Handbook .

Karima 30 May 2021 AT 05:05 PM

Dear MLA staff, 1) In case i am quoting from multiple sources by the same author, am i required to introduce again the source i am quoting from in the beginning of my sentence? (Quotes are used in multiple paragraphs)

For guidance on citing multiple sources by the same author, see 6.8 in the ninth edition of the MLA Handbook .

Yves 23 June 2021 AT 06:06 PM

Hello, is there a specific rule about how to format a range of page numbers in the parenthetical citation? For example, could (Eden 44-45) be written as (Eden 44-5), or is only one example correct?

Laura Kiernan 24 September 2021 AT 02:09 PM

For information about styling number ranges, see section 2.139 of the ninth edition of the MLA Handbook .

Faliravo 11 August 2021 AT 05:08 AM

Good morning MLA team, My professor insists that I include the year of publication for in-text citations. Is it going to be okay if I insert the year between the author and the page number?

Thank you very much for your consideration.

Laura Kiernan 24 September 2021 AT 01:09 PM

Your approach to modifying our style in accordance with your professor’s instructions works, but we would suggest confirming that styling with your professor.

Pauline 14 September 2021 AT 11:09 PM

How do I cite an entire work. For example, if I want to say Toni Morrison's the "Bluest Eye" has been used as a textbook for many English literature classes, I suppose I shouldn't put any page number in the parenthetical citation. But I can't find any MLA references on this.

See section 4.14 of the ninth edition of the MLA Handbook .

myron glassenberg 04 February 2022 AT 01:02 PM

if source is the whole book, how do I cite in text and in works cited pages. e.g. freud (no page number) Freud , ( 1892) The Pleasure Principle.

Rita Rozzi 20 September 2023 AT 07:09 PM

There is no section 4.14 in the ninth edition. Do you have any updated information? Thank you.

Laura Kiernan 21 September 2023 AT 03:09 PM

Section 4.14, which is titled "Passing Mentions," can be found in chapter 4 of the ninth edition of the handbook.

Lauren McFall 13 October 2021 AT 02:10 PM

Students often refer to the same source consecutively across more than one sentence. I'm having a hard time finding information about the preferred approach according to the MLA. As a parallel, APA makes a specific recommendation - "cite the source in the first sentence in which it is relevant and do not repeat the citation in subsequent sentences as long as the source remains clear and unchanged" https://apastyle.apa.org/style-grammar-guidelines/citations/appropriate-citation

Laura Kiernan 20 October 2021 AT 04:10 PM

See 6.45 of the ninth edition of the MLA Handbook .

Ruth Schafer 01 December 2022 AT 07:12 PM

6.45 out of the MLA Handbook's ninth edition does not provide an example of how to cite a multi-sentence paraphrase when using an unpaginated source. Can you give an example of how to cite a multi-sentence paraphrase where the source does not have published page numbering?

Should I introduce the source in my prose and then again at the end of the multi-sentence paraphrase in parentheses when I have finished citing the paraphrase? Example: John Smith from Smith Architecture explains that crawl space foundations are...blah blah blah. These foundations are most commonly used in midwestern constructions where the frost line is...blah, blah, blah. Keep writing the paraphrase and then at the end of the final sentence instead of a page citation write the author's last name (Smith). This way if you switch to a different source, at least the reader knows that you have finished with the Smith source and have moved on to your own commentary or another source's information. Usually, I'd use a page citation at the end of the paraphrase, but when dealing with a source that does not have page numbering, I'm unsure what to do.

Lizzie 18 October 2021 AT 10:10 PM

If I only use textual evidence from the novel I'm examining, do I need to include the authors name with each in text citation? There are no other works cited, so it seems redundant/clutter-y to me

Kayden 29 October 2021 AT 05:10 PM

If I'm trying to cite multiple paragraphs from the same source would it be correct to say (par. 3 and 13) or should it be (par. 3, 13) and is it different if they are next to each other too like (par. 6-7) or (par. 6 and 7).

Laura Kiernan 04 November 2021 AT 11:11 AM

See sections 6.18–6.20 of the ninth edition of the MLA Handbook .

Rachel 17 November 2021 AT 01:11 PM

When citing from an online source without pagination, if you include the author's name in the introduction to the quote, do you need to include anything in parentheses like the article title?

Laura Kiernan 22 November 2021 AT 12:11 PM

See section 6.26 of the ninth edition of the MLA Handbook .

July 25 November 2021 AT 05:11 PM

When quoting an online source (e.g. a website), do I have to indicate the fact that it's an online source in the in-text-citations as in (Name [online]) or is the author's name enough?

Thank you in advance for your answer.

Laura Kiernan 29 November 2021 AT 10:11 AM

According to MLA style, an in-text citation for an online work should not note that the work is online.

Pinkie 19 March 2022 AT 08:03 PM

If I'm writing a response paper, and I need to summarize the whole article to introduce it, then should I use in-text citation?

Laura Kiernan 25 March 2022 AT 01:03 PM

For guidance on paraphrasing, see sections 4.5–4.8 of the ninth edition of the MLA Handbook .

Kay 09 April 2022 AT 06:04 PM

Hi, am I supposed to include the DOI when one is available in the citation? If I cite the print version of a journal article that has a DOI, still include the DOI in the citation? Thank you!

Laura Kiernan 11 April 2022 AT 11:04 AM

Thank you for your questions. For guidance on including a DOI in your works-cited-list entry, see sections 5.84 and 5.93 in the ninth edition of the MLA Handbook .

Mike 16 April 2022 AT 05:04 PM

Website in-text Citation...

When I'm writing an in-text citation for a website, I'm seeing all manner of different things to include. Do I need to add the author name and year of publishing for the article?\ Do I just need the website name? I'm not really understanding what I need to add or obtain for such a citation within the text I'm writing.

I'm writing a book on my life, and I'm quoting a particular webpage to show one particular angle of an argument I'm making, and, of course, it's not common knowledge, so I want to make sure that I follow all the rules for this kind of thing, so I don't get in trouble with the author(s) of the sources I have quoted from...

Thank you for your questions about MLA style. For guidance on in-text citations for web pages, see section 6.26 of the ninth edition of the MLA Handbook .

Cynthia 21 May 2022 AT 10:05 PM

When you're doing an In-text citations do you put the quotations over the chapter title and then quotations over what you get from the text or do you italicize the title?

I'm trying to find how to put in the in-text citation for a UN declaration article but can only find the "Resolutions of International Governing Bodies" on page 446 of the 9th edition but not how to out it in without an author.

Kim 27 September 2022 AT 12:09 PM

I'm quoting a passage from an unpublished manuscript, and it is not the only work I'm citing by the author, but the only one without a year. So using "Smith 1995, 82" is not possible. What would an in-text citation for this case look like?

Jen 17 November 2022 AT 08:11 PM

How do I cite a news cast for in-text citation like ABC News?

Samantha 04 December 2022 AT 05:12 PM

Hi, For MLA format, should a quote where you need to de-capitalize the first letter be written as "you want" or "(y)ou want". Thanks!

Stewart, David W. Focus groups. In: Frey, B.B. (ed.) The SAGE Encyclopedia of Educational Research, Measurement, and Evaluation, vol. 2, pp. 687–692. Thousand Oaks: Sage Publications 2018 In this case, how is the correct form to write, because the article is IN the the book?

Eros Karadzhov 15 February 2023 AT 02:02 PM

If we have a sentence that is a statement, but at the end we quote a question, which punctuation mark do we keep, the question mark or the period; maybe both? Example: (1) The author ends his poem with the following question on purpose: "Or does it explode?" (Hughes 11). (2) The author ends his poem with the following question on purpose: "Or does it explode" (Hughes 11)?

Which would be correct, or maybe both are wrong?

Thank you in advance!

Laura Kiernan 16 February 2023 AT 03:02 PM

Thank you for your question. For guidance on quotations ending in a question mark, see section 6.53 of the ninth edition of the MLA Handbook .

Anonymous 08 March 2023 AT 05:03 PM

What about online articles with no known author or multiple authors? What should the in-text citation look like?

Maria 25 March 2023 AT 04:03 PM

Please settle a dispute with my colleagues. I encourage composition students to avoid listing the title of journal articles within the essay unless it is especially relevant because it clutters their arguments. I came to this conclusion from my interpretation of this statement from MLA: "All in-text references should be concise. Avoid, for instance, providing the author’s name or title of a work in both your prose and parentheses." Could someone please provide an answer or further clarification?

Erika Suffern 30 March 2023 AT 04:03 PM

You are right to identify a principle of concision in our guidelines. That said, it is not wrong to mention a title in prose, but it should be done, as you note, when relevant–not as a de rigeur practice or for “filler.” As Eric Hayot notes in The Elements of Academic Style: Writing for the Humanities (Columbia UP, 2014), “giving the title” in prose “suggests fuller forthcoming treatment” (159). Another reason for including the title in prose might be to call attention to something about it. Many writers who do mention a title in prose fear having an incomplete citation and are tempted also to include the title in a parenthetical reference, which is unnecessary.

Jay 29 April 2023 AT 12:04 AM

How do I in-text cite a direct quote from the introduction of an ebook with no page numbers? Would I write (Author "Introduction") or just write (Author)?

Kiara 11 February 2024 AT 03:02 PM

Hello! I am a university student who is currently creating works cited entries and in-text citations for a reflection essay. How do I properly cite professor and peer comments?

Therese Willis 30 July 2024 AT 10:07 PM

What is the proper way to write MLA in-text citattion from a website for this: According to an article titled “Caitlin Clark: Changing the Game” (McCord, 2024), Clark put women’s basketball on the map and taught millions what it meant to love the sport. She has shown off her iconic logo shot and her ability to control the court when needed, all while maintaining a professional image.

Harvard Guide to Using Sources 

• The Honor Code
• In-Text Citations

In APA style, you use parenthetical citations within the text of your paper to credit your sources, to show how recently your sources were published, and to refer your reader to a more detailed citation of the source in the reference list at the end of your paper. You should use parenthetical citations when you paraphrase, quote, or make any reference to another author's work. A parenthetical citation in APA style includes the author's last name as well as the year in which the work was published, with a comma between them. If you are referring directly to a specific page in the source, you should also include the page number in your parenthetical citation. APA requires you to cite page numbers when you are quoting directly from the source. If you are paraphrasing, which is more common in the social sciences, you generally do not need to include a page number. If you have questions about whether you should include page numbers when citing in APA, you should consult your instructor.

If you mention the author's name and/or the year of publication in the sentence preceding the citation, you do not need to include them in the parenthetical citation. When you name the author in the sentence, you should include the publication year in parentheses right after the author’s name—do not wait until the end of the sentence to provide that information.

When you include a parenthetical citation at the end of a sentence, the punctuation for your sentence appears after the citation.

Citing author and date in a parenthetical citation

When you don’t mention either the author or the date of publication in your sentence, you should include both the author and the year, separated by a comma, in the parenthetical citation. 

Colleges and universities need to create policies that foster inclusion for low-income students (Jack, 2019).         

Citing when author’s name is mentioned in body of paper

When you mention the author’s name in your sentence, the year of publication should immediately follow the author’s name.

Anthony Jack’s (2019) study of low-income students on an elite college campus revealed that these schools are often unprepared to support the students they admit.

Jack (2019) studied the ways low-income students experience elite college campuses.

Citing page numbers

When you cite a direct quote from the source or paraphrase a specific point from the source, you should include the page number in the parenthetical citation at the end of the sentence. When you refer to a specific page or pages of the text, first list the year of publication and then list "p." followed by the page number or "pp." followed by the range of pages. If you refer to a specific chapter, indicate that chapter after the year.              

The author contends that “higher education in America is highly unequal and disturbingly stratified” (Jack, 2019, p. 4).

Jack (2019) contends that “higher education in America is highly unequal and disturbingly stratified” (p. 4).

Citing sources with more than one author

When you cite a source that has two authors, you should separate their names with an ampersand in the parenthetical citation.

The authors designed a study to determine if social belonging can be encouraged among college students (Walton & Cohen, 2011). 

If a work has three or more authors , you should only include the first author's name followed by et al. ( Et al. is the shortened form of the Latin et alia , which means “and others.”)

The implementation of postpartum contraceptive programs is both costly and time consuming (Ling et al., 2020).

Attributing a point to more than one source  

To attribute a point or idea to multiple sources, list them in one parenthetical citation, ordered alphabetically by author and separated by semicolons. Works by the same author should be ordered chronologically, from oldest to most recent, with the publication dates separated by commas.

Students who possess cultural capital, measured by proxies like involvement in literature, art, and classical music, tend to perform better in school (Bourdieu & Passeron, 1977; Dumais, 2002; Orr, 2003).

Citing multiple works by the same author 

If your reference list includes multiple works by the same author in the same year, identify them in your parenthetical citations and in your reference list by a lowercase letter after the year, assigning each letter in alphabetical order by the title of the work. When establishing the alphabetical order of works in your reference list, do not count the words "A" or "The" when they appear as the first word in a title.

One union-endorsed candidate publicly disagreed with the teachers' union on a number of issues (Borsuk, 1999a).

Citing multiple authors with the same last name        

If your reference list includes sources by multiple authors with the same last name, list each author's initials before their last name, even when the works were published in different years.

The question of whether a computer can be considered an author has been asked for longer than we might expect (B. Sobel, 2017).

Citing when no author is listed           

To refer to a work that is listed in your reference list by title rather than by author, cite the title or the first few words of the title.

The New York Times painted a bleak picture of the climate crisis (“Climate Change Is Not Negotiable,” 2022).

Citing when no date is listed

If the work you are citing has no date listed, you should put “n.d.” for “no date” in the parenthetical citation.

Writing research papers is challenging (Lam, n.d.). 

Citing a specific part of a source that is not a page number

To refer to a specific part of a source other than page number, add that after the author-date part of your citation. If it is not clear whether you are referring to a chapter, a paragraph, a time stamp, or a slide number, or other labeled part of a source, you should indicate the part you are referring to (chapter, para., etc.).

In the Stranger Things official trailer, the audience knows that something unusual is going to happen from the moment the boys get on their bicycles to ride off into the night (Duffer & Duffer, 0:16).

APA In-Text Citations and Sample Essay 7th Edition

This handout focuses on how to format in-text citations in APA.

Proper citation of sources is a two-part process . You must first cite each source in the body of your essay; these citations within the essay are called in-text citations . You MUST cite all quoted, paraphrased, or summarized words, ideas, and facts from sources. Without in-text citations, you are technically in danger of plagiarism, even if you have listed your sources at the end of the essay.

In-text citations point the reader to the sources’ information on the references page. The in-text citation typically includes the author's last name and the year of publication. If you use a direct quote, the page number is also provided.

More information can be found on p. 253 of the 7th edition of the Publication Manual of the American Psychological Association.

Citation Rules

Direct quotation with the author named in the text.

Heinze and Lu (2017) stated, “The NFL shifted its responses to institutional change around concussions significantly as the field itself evolved” (p. 509).

Note: The year of publication is listed in parenthesis after the names of the authors, and the page number is listed in parenthesis at the end of the quote.

Direct Quotation without the Author Named in the Text

As the NFL developed as an organization, it “shifted its responses to institutional change around concussions significantly” (Heinze & Lu, 2017, p. 509).

Note: At the end of the quote, the names of the authors, year of publication, and page number are listed in parenthesis.

Paraphrase with 1-2 Authors

As the NFL developed as an organization, its reactions toward concussions also transformed (Heinze & Lu, 2017).

Note: For paraphrases, page numbers are encouraged but not required.

Paraphrase with 3 or More Authors

To work toward solving the issue of violence in prisons begins with determining aspects that might connect with prisoners' violent conduct (Thomson et al., 2019).

Direct Quotation without an Author

The findings were astonishing "in a recent study of parent and adult child relationships" ("Parents and Their Children," 2007, p. 2).

Note: Since the author of the text is not stated, a shortened version of the title is used instead.

Secondary Sources

When using secondary sources, use the phrase "as cited in" and cite the secondary source on the References page.

In 1936, Keynes said, “governments should run deficits when the economy is slow to avoid unemployment” (as cited in Richardson, 2008, p. 257).

Long (Block) Quotations

When using direct quotations of 40 or more words, indent five spaces from the left margin without using quotation marks. The final period should come before the parenthetical citation.

At Meramec, an English department policy states:

To honor and protect their own work and that of others, all students must give credit to proprietary sources that are used for course work. It is assumed that any information that is not documented is either common knowledge in that field or the original work of that student. (St. Louis Community College, 2001, p. 1)

Website Citations

If citing a specific web document without a page number, include the name of the author, date, title of the section, and paragraph number in parentheses:

In America, “Two out of five deaths among U.S. teens are the result of a motor vehicle crash” (National Center for Injury Prevention and Control, 2004, Overview section, para. 1).

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Harvard Referencing Guide

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

Vancouver Referencing Guide

APA referencing, used in the social and behavioural sciences, uses author–date in-text citations corresponding to an alphabetical reference list at the end.

MHRA referencing, used in the humanities, uses footnotes in the text with source information, in addition to an alphabetised bibliography at the end.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

Correct my document today

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

What are In-Text Citations?

You must cite (give credit) all information sources used in your essay or research paper whenever and wherever you use them.

When citing sources in the text of your paper, you must list:

● The author’s last name

● The year  the information was published.

Types of In-Text Citations: Narrative vs Parenthetical

A  narrative citation gives the author's name as part of the sentence .

• Example of a Narrative Citation: According to Edwards (2017) , a lthough Smith and Carlos's protest at the 1968 Olympics initially drew widespread criticism, it also led to fundamental reforms in the organizational structure of American amateur athletics.

A  parenthetical citation puts the source information in parentheses—first or last—but does not include it in  the narrative  flow.

• Example of a Parenthetical Citation:  Although Tommie Smith and John Carlos paid a heavy price in the immediate aftermath of the protests, they were later vindicated by society at large (Edwards, 2017) .

Full citation for this source (this belongs on the Reference Page of your research paper or essay):

Edwards, H. (2017).  The Revolt of the Black Athlete: 50th Anniversary Edition.  University of Illinois Press.

Sample In-text Citations

Note: This example is a  direct quote. It is an exact quotation directly from the text of the article. All direct quotes should appear in quotation marks: "...."

Try keeping direct quotes to a minimum in your writing. You need to show your understanding of the source material by being able to paraphrase or summarize it. 

List the author’s last name only (no initials) and the year the information was published, like this:

(Dodge, 2008 ). ( Author , Date).

IF you use a direct quote, add the page number to your citation, like this: 

( Dodge , 2008 , p. 125 ).

( Author , Date , page number )

What information should I cite in my paper/essay?

Credit these sources when you mention their information in any way: direct quotation, paraphrase, or summarize.

What should you credit?

Any information that you learned from another source, including:

● statistics

EXCEPTION: Information that is common knowledge: e.g., The Bronx is a borough of New York City.

Citing Sources in the Text of your Paper

When writers use an outside source, they must give credit to the original writer or creator of that source. This also allows a reader to easily make note of the source’s bibliographic entry. Just as each style guide has rules for creating a citation in a bibliography at the end of a text, each guide also has certain rules for citing the use of sources within the text of the essay.

The following are basic guidelines for citing sources in the text of your paper when using the MLA, APA, Chicago, ASA, or Turabian style guides. These guidelines may not account for every citation situation. Since citing sources is not a creative enterprise, you should consult the appropriate print version of the style guide when you have questions about citation.

MLA: In-Text Citations

MLA citation style requires that writers cite a source within the text of their essay at the end of the sentence in which the source is used.

General Guidance on in-text citations (or reference to your source) The parenthetical reference should be inserted after the last quotation mark but before the period at the end of the sentence.

General Form: (Author Last Name Page #)

Example: (Smith 42)

If two quotations from different sources are used in the same sentence The in-text citation associated with a particular quote should be placed as close to the quotation as possible without interrupting the flow of the sentence.

Example for two sources in one sentence: According to one researcher, “the design thinking process is not meant to be a formula,” (Spencer 58) whereas others might argue that steps and formulas are in fact important like Walker suggests: “following a specific path towards design success is necessary for achieving outlined goals,” (21).

If a paragraph includes several quotations from a single source A single in-text citation may be placed at the end of the paragraph. Page numbers should be included for each quotation organized by placement in the paragraph. In the following example, the first quotation from Smith appeared on page 43 of the text. The second quotation used in the paragraph came from page 12.

Example: (Smith 43, 12)

If the author is included more than once on the Works Cited page The following form should be used. Note that the format of the title on the Works Cited sheet should be mirrored in the in-text citation.

General Form: (Author Last, “Title Fragment” Page #) or (Author Last,  Title Fragment Page #)

Examples: (Smith, “Who Moved” 42) or (Smith, Big Changes 172)

If you have more than one author:

Two: (Brown and Sullivan 42)

Three: (Brown, Sullivan, and Grayson 158)

Four or more: (Brown, et al. 38)

If there is no author A title fragment should be used to make a connection between the use of the source and the citation for the source on the Works Cited page.

General Form: (“Title Fragment” Page #) or ( Title Fragment  Page #)

Examples: (“Library Links” 13) or ( Building a Bookshelf  42)

For more information related to MLA in-text citations, see the MLA Handbook , 8th ed. (pages 54-58). This title is on reserve at the circulation desk at the front of the library on the 3rd floor near the main entrance.

APA: Parenthetical In-Text Citations

To cite a source in the text of an essay, APA advocates two methods: in-text citations and attribution within the essay’s content. in-text citations should be included immediately after the quotation marks used in direct quotations or immediately after the use of the source, even if this means including the parenthetical reference in the middle of the sentence.

The following is the general form for parenthetical citations in APA style:

In-text citation: (Author Last Name, Year of Publication) Example: (Smith, 1988)

To make the citation of the source less distracting The APA also suggests mentioning the author in the essay’s content so that only the year of publication and page number may be required in the parenthetical reference.

Attribution in text: Author Last Name (Year of Publication) has argued this point. Example: Smith (1988) has argued this point.

Page numbers are not required in APA in-text citations. However, it is highly suggested that these be included. To include references to a specific part of the text, add the page number or chapter number after the year.

Examples: Smith (1988, p. 244) has written that… or Smith (1988, chap. 5) has written that…

When a work has two authors Both names should be cited every time the reference is required. Use an ampersand (&) to separate the names of authors. If a text has been authored by more than five individuals, the full listing of authors is not required in the first reference or any subsequent in-text references.

The first mention of the reference: Johnson, Smith, and Brown (1999) agree that… Subsequent mention: Johnson et al. (1999) agree that…

If a group or corporation is the author The full name of the group or corporation should be included in place of the author’s name. If an organization has a recognizable abbreviation, this may be used in subsequent references.

The first mention of the reference: (American Medical Association, 2002) Subsequent mention: (AMA, 2002)

If no author is given for a specific text Use the first couple of words of the title in place of the author’s last name. Title fragments should be formatted using the same punctuation as titles on the References page.

Examples of attribution in the text:

The recent publication  Plagiarism and You  (2002) offers some explanation…

In “Five Ways to Protect Yourself” (2000) one can find…

Examples of attribution at the end of the sentence: ( Plagiarism and You , 2002) or (“Five Ways to Protect Yourself,” 2000)

When no date is given for the publication of a text (as is the case with many websites) Include the abbreviation “n.d.” (which stands for “no date”) in place of the year of publication.

Example: In the article “Five Ways to Protect Yourself” (n.d.) one can find…

For more information related to in-text citations (or in-text referencing) using the APA format, see the Publication Manual of the American Psychological Association , 7th ed. pages 261-269. A copy of this manual is available on the 3rd floor of the library at the circulation desk.

Chicago: Notes Style

In Chicago’s Documentation Style 1, also known as notes form, the use of research sources is indicated in the text with a numerical subscript that corresponds to an entry at the end of the paper. These are called endnotes. Although footnotes (or notes at the bottom of the page) are sometimes required, endnotes have become the predominant form of notes citations.

When using endnotes to indicate the use of research sources, writers must also include a bibliography at the end of the essay. The note and the bibliographic entry include almost identical information but in a different format.

As the formats for notes are contingent on the format of the source for which the note is written, examples of note formats are included with the bibliographic examples available through the  Citing Sources  link. The B: entry would be included in the Bibliography at the end of the paper, while the N: entry gives examples to be used in footnotes or endnotes.

For further information on note format or other issues related to citing sources using the Chicago style, see  The Chicago Manual of Style , 16th ed.

Chicago: Author/Date Style

Documentation 2, also called the Author-Date style, requires the use of parenthetical references in the text of the essay as well as a list of References.

Parenthetical references should be placed at the end of the sentence, before the period, when a resource has been used. If the sentence is either long enough or complex enough so that the cited portion of the sentence is not obvious, the parenthetical reference may instead be inserted immediately after the use of information from the source. Page numbers should be included whenever possible.

General Form:  (Author Last Name Year of Publication, Page #)

Example:  (Smith 1992, 142)

The following examples illustrate parenthetical reference formats for works with more than one author.

(Smith and Johnson 1998, 14)

(Smith, Johnson, and White 2001, 42)

(Smith et al. 1998, 203)

(National Alliance for Social Consideration 1932, 11)

When organizations or corporate authors are the author of a text, the name of the organization may be shortened to its most basic title. Abbreviations for the organization are not encouraged.

In the Chicago style, daily newspapers are rarely included in a list of References. Instead, attribution may be given to information from a daily newspaper in a parenthetical reference.

General Form:  ( Newspaper Name , Day Month Year of Publication, Section and Page #)

Examples:  ( San Antonio Express-News , 2 June 2005, B2)

( New York Times , 2 June 2005, A2)

( Durant Daily Democrat , 2 June 2005, 3)

The Chicago style guide does not offer examples for creating parenthetical references when there is no given author. Standard practice has been to include the title of the work in place of the author. The title should be formatted in the same manner as the formatting in the References list entry.

( Plagiarism and You  2002, 142)

(“Five Ways to Protect Yourself” 2000, 33)

Electronic sources commonly lack a date of publication, as do other sources. When there is no date of publication listed for a source, include the abbreviation “n.d.” in place of the date.

(Statistics for Water Rights n.d.)

For further information on citing sources using the Chicago style, see The Chicago Manual of Style, 16th ed.

If the author’s name is mentioned in the text, use a parenthetical reference to show the year of publication at the end of the sentence.

…Welch contends that this is not the case (1991).

If the author’s name is not mentioned in the text, it should be included with the year of publication within parentheses.

…but it has been argued that this was not the case (Welch 1991).

Page numbers should be included within parentheses after the year of publication. These are separated by a colon and no spaces.

…but it has been argued that this was not the case (Welch 1991:136).

The following forms should be used for multiple authors:

A recent study confirmed her belief (Johnson and Smith 1995:34).

This was reinforced by recent research on the topic (Johnson, Smith, and Marcus 1999)

If a text has more than three authors, the term “et al.” with no additional punctuation marks may be used after the first author listed in the publication credits.

This was not accurate according to a recent study (Johnson et al. 2003).

If multiple sources are cited for the same statement, the author and publication year should be distinguished from other texts with a colon. Cited texts should be arranged by author name or by date; arrangement should be consistent throughout the paper.

Some studies have refuted these arguments (Benson 1993; Nguyen 1999; Brown and Goggans 2000).

For additional information on in-text citation using the ASA style, see the  American Sociological Association Style Guide , Third ed., pp. 45-47.

In the Turabian citation style, writers may use one of two forms in citing their resources: endnotes or author/date parenthetical references. Writers using the Turabian style may use the Chicago formats for both endnotes as references and for parenthetical references. Refer to Kate L. Turabian’s  A Manual for Writers , 7th ed., pp. 143-145 (notes style) and pp. 217-220 (author-date style) for more information.

"Write an essay and back it up with facts."

How many times have you heard a teacher or professor say this? But many students might wonder what exactly counts as a fact, and what doesn't. That means they don't know when it is proper to cite a source, and when it's OK not to use a citation.

Dictionary.com states that a fact is:

• Something demonstrated to exist or known to have existed.

"Demonstrated" is a hint here. What the teacher means when she/he tells you to use facts is that you need to back up your claims with some evidence that supports your claims (sources). It's one trick that teachers use to make sure you actually use some references when you write a paper, instead of simply offering a list of your opinions.

This may sound easy, but it's actually tough sometimes to know when you need to back up a statement with evidence and when it is fine to leave a statement unsupported.

When to Cite a Source

You should use evidence ( citations ) any time you make a claim that is not based on a well-known fact or common knowledge. Here's a list of situations when your teacher would expect a citation:

• You make a specific claim that could be challenged--like London is the foggiest city in the world. 
• You quote somebody.
• You make a specific claim that is not common knowledge like the Indian Ocean is the youngest of the world's major oceans.
• You paraphrase information from a source (give the meaning but change the wording).
• Offer an authoritative (expert) opinion--like "germs cause pneumonia."
• You got an idea from somebody else, even through email or conversation.

Although there may be interesting facts that you have believed or know for many years, you will be expected to provide proof of those facts when you're writing a paper for school.

Examples of Claims You Should Support

• Hot water can freeze faster than cold water.
• Poodles are friendlier than Dalmatians.
• American Chestnut trees are nearly extinct.
• Eating while driving is more dangerous than talking on the cell phone while driving.
• Thomas Edison invented a vote counter.

When You Don't Need to Cite a Source

So how do you know when you do not need to cite a source? Common knowledge is basically a fact that practically everyone knows, like the fact that George Washington was a U.S. president.

More Examples of Common Knowledge or Well-Known Facts

• Bears hibernate in the winter.
• Fresh water freezes at 32 degrees F.
• Many trees shed their leaves in the fall.
• Some trees do not shed their leaves in the fall.
• Bears hibernate.

A well-known fact is something that many people know, but it is also something that a reader could look up easily if he/she didn't know.

• It's best to plant flowers in the early spring.
• Holland is famous for its tulips.
• Canada has a multilingual population.

If you're not really certain about something being common knowledge, you could give it the little sister test. If you have a younger sibling, ask him or her the subject you're pondering. If you get an answer, it could be common knowledge!

A Good Rule of Thumb

A good rule of thumb for any writer is to go ahead and use a citation when you're not certain whether or not the citation is necessary. The only risk in doing this is littering your paper with unnecessary citations that will drive your teacher crazy. Too many citations will give your teacher the impression that you are attempting to stretch your paper to a certain word count!

Simply trust your own best judgment and be honest with yourself. You'll get the hang of it soon!

Free MLA Citation Generator

Generate accurate citations in MLA format automatically, with MyBib!

😕 What is an MLA Citation Generator?

An MLA citation generator is a software tool designed to automatically create academic citations in the Modern Language Association (MLA) citation format. The generator will take information such as document titles, author, and URLs as in input, and output fully formatted citations that can be inserted into the Works Cited page of an MLA-compliant academic paper.

The citations on a Works Cited page show the external sources that were used to write the main body of the academic paper, either directly as references and quotes, or indirectly as ideas.

👩‍🎓 Who uses an MLA Citation Generator?

MLA style is most often used by middle school and high school students in preparation for transition to college and further education. Ironically, MLA style is not actually used all that often beyond middle and high school, with APA (American Psychological Association) style being the favored style at colleges across the country.

It is also important at this level to learn why it's critical to cite sources, not just how to cite them.

🙌 Why should I use a Citation Generator?

Writing citations manually is time consuming and error prone. Automating this process with a citation generator is easy, straightforward, and gives accurate results. It's also easier to keep citations organized and in the correct order.

The Works Cited page contributes to the overall grade of a paper, so it is important to produce accurately formatted citations that follow the guidelines in the official MLA Handbook .

⚙️ How do I use MyBib's MLA Citation Generator?

It's super easy to create MLA style citations with our MLA Citation Generator. Scroll back up to the generator at the top of the page and select the type of source you're citing. Books, journal articles, and webpages are all examples of the types of sources our generator can cite automatically. Then either search for the source, or enter the details manually in the citation form.

The generator will produce a formatted MLA citation that can be copied and pasted directly into your document, or saved to MyBib as part of your overall Works Cited page (which can be downloaded fully later!).

MyBib supports the following for MLA style:

How to cite ChatGPT

We, the APA Style team, are not robots. We can all pass a CAPTCHA test , and we know our roles in a Turing test . And, like so many nonrobot human beings this year, we’ve spent a fair amount of time reading, learning, and thinking about issues related to large language models, artificial intelligence (AI), AI-generated text, and specifically ChatGPT . We’ve also been gathering opinions and feedback about the use and citation of ChatGPT. Thank you to everyone who has contributed and shared ideas, opinions, research, and feedback.

In this post, I discuss situations where students and researchers use ChatGPT to create text and to facilitate their research, not to write the full text of their paper or manuscript. We know instructors have differing opinions about how or even whether students should use ChatGPT, and we’ll be continuing to collect feedback about instructor and student questions. As always, defer to instructor guidelines when writing student papers. For more about guidelines and policies about student and author use of ChatGPT, see the last section of this post.

Quoting or reproducing the text created by ChatGPT in your paper

If you’ve used ChatGPT or other AI tools in your research, describe how you used the tool in your Method section or in a comparable section of your paper. For literature reviews or other types of essays or response or reaction papers, you might describe how you used the tool in your introduction. In your text, provide the prompt you used and then any portion of the relevant text that was generated in response.

Unfortunately, the results of a ChatGPT “chat” are not retrievable by other readers, and although nonretrievable data or quotations in APA Style papers are usually cited as personal communications , with ChatGPT-generated text there is no person communicating. Quoting ChatGPT’s text from a chat session is therefore more like sharing an algorithm’s output; thus, credit the author of the algorithm with a reference list entry and the corresponding in-text citation.

When prompted with “Is the left brain right brain divide real or a metaphor?” the ChatGPT-generated text indicated that although the two brain hemispheres are somewhat specialized, “the notation that people can be characterized as ‘left-brained’ or ‘right-brained’ is considered to be an oversimplification and a popular myth” (OpenAI, 2023).

OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

You may also put the full text of long responses from ChatGPT in an appendix of your paper or in online supplemental materials, so readers have access to the exact text that was generated. It is particularly important to document the exact text created because ChatGPT will generate a unique response in each chat session, even if given the same prompt. If you create appendices or supplemental materials, remember that each should be called out at least once in the body of your APA Style paper.

When given a follow-up prompt of “What is a more accurate representation?” the ChatGPT-generated text indicated that “different brain regions work together to support various cognitive processes” and “the functional specialization of different regions can change in response to experience and environmental factors” (OpenAI, 2023; see Appendix A for the full transcript).

Creating a reference to ChatGPT or other AI models and software

The in-text citations and references above are adapted from the reference template for software in Section 10.10 of the Publication Manual (American Psychological Association, 2020, Chapter 10). Although here we focus on ChatGPT, because these guidelines are based on the software template, they can be adapted to note the use of other large language models (e.g., Bard), algorithms, and similar software.

The reference and in-text citations for ChatGPT are formatted as follows:

• Parenthetical citation: (OpenAI, 2023)
• Narrative citation: OpenAI (2023)

Let’s break that reference down and look at the four elements (author, date, title, and source):

Author: The author of the model is OpenAI.

Date: The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title: The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).

Other questions about citing ChatGPT

You may have noticed the confidence with which ChatGPT described the ideas of brain lateralization and how the brain operates, without citing any sources. I asked for a list of sources to support those claims and ChatGPT provided five references—four of which I was able to find online. The fifth does not seem to be a real article; the digital object identifier given for that reference belongs to a different article, and I was not able to find any article with the authors, date, title, and source details that ChatGPT provided. Authors using ChatGPT or similar AI tools for research should consider making this scrutiny of the primary sources a standard process. If the sources are real, accurate, and relevant, it may be better to read those original sources to learn from that research and paraphrase or quote from those articles, as applicable, than to use the model’s interpretation of them.

We’ve also received a number of other questions about ChatGPT. Should students be allowed to use it? What guidelines should instructors create for students using AI? Does using AI-generated text constitute plagiarism? Should authors who use ChatGPT credit ChatGPT or OpenAI in their byline? What are the copyright implications ?

On these questions, researchers, editors, instructors, and others are actively debating and creating parameters and guidelines. Many of you have sent us feedback, and we encourage you to continue to do so in the comments below. We will also study the policies and procedures being established by instructors, publishers, and academic institutions, with a goal of creating guidelines that reflect the many real-world applications of AI-generated text.

For questions about manuscript byline credit, plagiarism, and related ChatGPT and AI topics, the APA Style team is seeking the recommendations of APA Journals editors. APA Style guidelines based on those recommendations will be posted on this blog and on the APA Style site later this year.

Update: APA Journals has published policies on the use of generative AI in scholarly materials .

We, the APA Style team humans, appreciate your patience as we navigate these unique challenges and new ways of thinking about how authors, researchers, and students learn, write, and work with new technologies.

How to Write an Argumentative Essay- Steps with Examples

Being a student and writing essays is not something everybody enjoys, but in my personal opinion as a writer, anyone can find contentment and pleasure in writing, especially when it comes to argumentative essays. While they may seem tricky to navigate, they offer this unique opportunity to express your opinions and make your voice heard. Consider this a growing process—once you overcome the challenges of writing argumentative essays, you will learn the art of agreeing or disagreeing with popular opinions and defending your stance. As far as the essay is concerned, I will show you how to master this process on how to write an argumentative essay.

When is an Argumentative Essay Written?

You will likely be required to write argumentative essays throughout your academic life, from high school to university. These assignments will present opportunities to develop and showcase your critical thinking and persuasive writing skills. Here are some scenarios where you might encounter the need to write argumentative essays:

Academic Assignments

Often assigned in school or college courses to help students develop critical thinking and persuasive writing skills. These assignments encourage students to research thoroughly, form coherent arguments, and present their viewpoints convincingly.

Debates and Discussions

Serve as the basis for presenting and defending viewpoints in academic or competitive settings. Argumentative essays provide a structured way to organize thoughts and evidence, helping participants articulate their arguments effectively during debates.

Opinion Pieces

Commonly used in newspapers, magazines, and online publications to influence public opinion on current issues. These essays allow writers to present their stance on controversial topics, backed by evidence and reasoning, to sway readers' views.

Policy Proposals

Utilized in government and policy-related fields to propose and defend specific policy changes or solutions to societal problems. Argumentative essays in this context present well-researched arguments to persuade policymakers and stakeholders of the necessity and viability of the proposed changes.

Persuasive Speeches

Prepared as a foundation for delivering persuasive speeches. Writing an argumentative essay helps speakers organize their thoughts and evidence logically, providing a solid framework for their oral presentations.

What is the Structure of an Argumentative Essay?

An argumentative essay uses factual evidence and logical support to convince the reader of a particular point of view. Here's a breakdown of the structure and what goes into each part of an argumentative essay:

Basic Argumentative Essay Structure

1.Introduction

Purpose: Introduce the topic, present the thesis, and set up the argument.

Hook: A sentence to grab the reader’s attention.

Background Information: Brief context about the topic.

Thesis Statement: The main argument or claim.

2.Body Paragraphs

Purpose: Present arguments and evidence to support the thesis and refute opposing arguments.

Topic Sentence: Introduces the main idea of the paragraph.

Evidence and Analysis: Present facts, statistics, quotes, or examples to support the argument.

Counterarguments and Rebuttals: Address opposing views and explain why they are invalid or less significant.

3.Conclusion

Purpose: Summarize the arguments, restate the thesis in light of the evidence presented, and offer final thoughts.

Restate Thesis: Reiterate the main argument.

Summarize Key Points: Highlight the main points made in the body paragraphs.

Final Thought: A closing statement that underscores the importance of the topic

How to Write an Argumentative Essay [4 Steps with Examples]

As an experienced writer, I've come to understand the structure of argumentative essays quite well. But what I found truly challenging when I first started was nailing the right approach. Many beginners, myself included at one point, fall into traps like letting personal biases creep in or thinking that being argumentative means being aggressive. Trust me, that's not the case at all!

In this section, I'm going to lay out an effective approach on how to write an argumentative essay step by step for beginners. I'll break it down in a way that I wish someone had done for me when I was starting out. Plus, I'll share some insider tips on tools like WPS Office that I've come to rely on to streamline my writing process. So let's learn how to write an argumentative essay with a few examples.

1.Brainstorming

When I sit down to craft an argumentative essay, my first step is to engage in a comprehensive brainstorming session. This is your opportunity to let your creativity run wild and explore every angle of your topic. Write down every idea that comes to you, whether it supports or opposes your topic. Remember, at this stage, there are no bad ideas.

Now, while there's nothing wrong with the classic pen and paper approach, I've found that using WPS Office takes my brainstorming to a whole new level. It's not just about having a digital notepad; the AI features often toss out ideas that I might never have thought of on my own. It's like having a creative partner who never gets tired! Let me show you how I use it:

Let's say our topic is "Are Electric Cars Better for the Environment?"

Step 1: Open WPS Office and type "@AI" on a blank document to activate WPS AI.

Step 2: Click on the "Brainstorm" option and enter your prompt. Make sure it's detailed and clearly explains what you want. Here's an example of an effective prompt:

"Generate a list of arguments both for and against the idea that electric cars are better for the environment. Consider factors like emissions, manufacturing processes, battery disposal, and energy sources"

Step 3: WPS AI will generate several arguments on both sides. If you want more, simply click "Rewrite”.

Jot down any valuable arguments before hitting "Rewrite", as you might not see the same ones again.

With these arguments in hand, you'll likely find yourself leaning towards one side of the debate. Armed with a variety of points and counterpoints, you'll be well-equipped to write an effective argumentative essay. Remember, a strong argumentative essay is built on a foundation of thorough preparation and diverse ideas.

2.Preparing

Now that we've generated our initial arguments and counterarguments, it's time to dive deeper into research to strengthen our position. Let's continue with our example topic: "Are Electric Cars Better for the Environment?"

Let's continue with our example topic: "Are Electric Cars Better for the Environment?" Our next step is to select the most impactful supporting arguments and conduct in-depth research to substantiate them with solid evidence. Simultaneously, we'll identify the strongest counterarguments and explore ways to address or neutralize them through our research.

All of this might seem a little overwhelming, but with the help of WPS AI, the research phase becomes significantly more manageable. As we gather research papers, we can upload them to WPS Office and quickly gain insights using the AI features.

Here's how to leverage WPS AI for efficient research:

Step 1: Open your research paper PDFs in WPS Office, then click on the WPS AI widget in the top right corner.

Step 2: In the WPS AI panel that appears on the right side of your screen, click "Upload" to add your PDF.

Step 3: Once processed, WPS AI will provide you with key insights from the PDF at a glance.

Step 4: For more specific information, click on the "Inquiry" tab and use the WPS AI chatbot to ask further questions about the PDF contents.

As you conduct your research, begin organizing your findings into an outline. Remember to structure your outline according to the elements we discussed in previous sections. This will ensure your outline contains all the necessary components for an effective argumentative essay.

3.First Drafting

Now that we have our research and outline ready, it's time to start writing our first draft. This is where your essay really starts to take shape. Don't worry about perfection at this stage—the goal is to get your ideas down coherently.

Using the outline we prepared during our research, you'll find it easier to organize your thoughts for your essay. To make things simpler, use WPS Office editing tools. When I write my essay, I always ensure it is properly formatted, giving it a cleaner look and helping me focus better.

Now, simply start your draft on WPS Office with an introduction, followed by a body paragraph, and conclude with a strong summary that reviews your main points and leaves the reader with something to think about.

Once you have your draft ready, make use of WPS Office's AI features, which can help you improve writing, shorten or elongate your paragraphs, and much more. Let's say you've written your first body paragraph, and it's a bit too long. So, let's shorten it with WPS AI:

Step 1: Select the paragraph you want to shorten, then click on the WPS AI icon in the hover menu.

Step 2: From the list of options, simply click on "Make shorter" to shorten your paragraph.

Step 3: WPS AI will display the shorter version on a small screen. Click on "Replace" to replace the original text with the shorter version.

4.Revising & Proofreading

Congratulations on completing your first draft! However, there is one crucial step remaining: revising and proofreading.  Revising and proofreading are where good essays become great essays.

A method I find most effective for revising my essay is reading it aloud. This technique helps in identifying awkward phrasing and run-on sentences that may go unnoticed when reading silently. As you read, ask yourself:

Does my introduction effectively grab the reader's attention and clearly state my thesis?

Do my body paragraphs each focus on a single main idea that supports my thesis?

Have I provided enough evidence to support each of my arguments?

Have I addressed potential counterarguments?

Does my conclusion effectively summarize my main points and leave a lasting impression?

You might find that you need to make some structural changes. For instance, you might realize that your second body paragraph would be more effective if it came first. Don't be afraid to move things around!

Once you have made the necessary changes to your essay, the next step is to ensure it does not have any grammatical errors. For this, I use WPS AI's spell check feature. With just a single click, WPS AI spell check ensures that my essay is complete and ready to be submitted!

FAQs about Writing an Argumentative Essay

1. what’s the difference between an expository essay and an argumentative essay.

An argumentative essay is typically more extensive and requires independent research to establish a unique claim regarding a specific topic. It includes a thesis statement that presents a debatable assertion, which must be supported by objective evidence. In contrast, an expository essay strives for objectivity but does not propose an original argument. Instead, it aims to clarify and explain a topic straightforwardly, such as a process or concept. Generally, expository essays are shorter and do not rely as heavily on research.

2. When do I need to cite sources?

In a college environment, accurately citing sources is vital for essays, research papers, and other academic assignments, but this requirement does not extend to exams or in-class tasks. Proper citations are needed for direct quotes, paraphrased material, and summaries, and it is necessary to provide complete source information in a bibliography or reference list. Following the specified citation style, such as APA or MLA, is essential for maintaining academic integrity. Whenever you utilize information or ideas from another work in college-level writing, proper citation is required to acknowledge the original source.

3. What is an Argumentative essay?

An argumentative essay is a type of writing that asserts a specific stance on a debatable issue, backing it up with reasoning and evidence. The main objective is to convince the reader to accept or seriously consider the author's viewpoint. This essay usually contains a clear thesis statement and develops arguments while addressing opposing views to reinforce its position. Ultimately, it seeks to encourage critical engagement with the topic at hand.

How to Quote | Citing Quotes in APA, MLA & Chicago

Published on April 15, 2022 by Shona McCombes and Jack Caulfield. Revised on May 31, 2023.

Quoting means copying a passage of someone else’s words and crediting the source. To quote a source, you must ensure:

• The quoted text is enclosed in quotation marks or formatted as a block quote
• The original author is correctly cited
• The text is identical to the original

The exact format of a quote depends on its length and on which citation style you are using. Quoting and citing correctly is essential to avoid plagiarism which is easy to detect with a good plagiarism checker .

How to cite a quote in apa, mla and chicago, introducing quotes, quotes within quotes, shortening or altering a quote, block quotes, when should i use quotes, other interesting articles, frequently asked questions about quoting sources.

Every time you quote, you must cite the source correctly . This looks slightly different depending on the citation style you’re using. Three of the most common styles are APA , MLA , and Chicago .

Citing a quote in APA Style

To cite a direct quote in APA , you must include the author’s last name, the year, and a page number, all separated by commas . If the quote appears on a single page, use “p.”; if it spans a page range, use “pp.”

An APA in-text citation can be parenthetical or narrative. In a parenthetical citation , you place all the information in parentheses after the quote. In a narrative citation , you name the author in your sentence (followed by the year), and place the page number after the quote.

Punctuation marks such as periods and commas are placed after the citation, not within the quotation marks .

• Evolution is a gradual process that “can act only by very short and slow steps” (Darwin, 1859, p. 510) .
• Darwin (1859) explains that evolution “can act only by very short and slow steps” (p. 510) .

Complete guide to APA

Citing a quote in mla style.

An MLA in-text citation includes only the author’s last name and a page number. As in APA, it can be parenthetical or narrative, and a period (or other punctuation mark) appears after the citation.

• Evolution is a gradual process that “can act only by very short and slow steps” (Darwin 510) .
• Darwin explains that evolution “can act only by very short and slow steps” (510) .

Complete guide to MLA

Citing a quote in chicago style.

Chicago style uses Chicago footnotes to cite sources. A note, indicated by a superscript number placed directly after the quote, specifies the author, title, and page number—or sometimes fuller information .

Unlike with parenthetical citations, in this style, the period or other punctuation mark should appear within the quotation marks, followed by the footnote number.

Make sure you integrate quotes properly into your text by introducing them in your own words, showing the reader why you’re including the quote and providing any context necessary to understand it.  Don’t  present quotations as stand-alone sentences.

There are three main strategies you can use to introduce quotes in a grammatically correct way:

• Add an introductory sentence
• Use an introductory signal phrase
• Integrate the quote into your own sentence

The following examples use APA Style citations, but these strategies can be used in all styles.

Introductory sentence

Introduce the quote with a full sentence ending in a colon . Don’t use a colon if the text before the quote isn’t a full sentence.

If you name the author in your sentence, you may use present-tense verbs , such as “states,” “argues,” “explains,” “writes,” or “reports,” to describe the content of the quote.

• In Denmark, a recent poll shows that: “A membership referendum held today would be backed by 55 percent of Danish voters” (Levring, 2018, p. 3).
• In Denmark, a recent poll shows that support for the EU has grown since the Brexit vote: “A membership referendum held today would be backed by 55 percent of Danish voters” (Levring, 2018, p. 3).
• Levring (2018) reports that support for the EU has grown since the Brexit vote: “A membership referendum held today would be backed by 55 percent of Danish voters” (p. 3).

Introductory signal phrase

You can also use a signal phrase that mentions the author or source, but doesn’t form a full sentence. In this case, you follow the phrase with a comma instead of a colon.

• According to a recent poll, “A membership referendum held today would be backed by 55 percent of Danish voters” (Levring, 2018, p. 3).
• As Levring (2018) explains, “A membership referendum held today would be backed by 55 percent of Danish voters” (p. 3).

Integrated into your own sentence

To quote a phrase that doesn’t form a full sentence, you can also integrate it as part of your sentence, without any extra punctuation .

• A recent poll suggests that EU membership “would be backed by 55 percent of Danish voters” in a referendum (Levring, 2018, p. 3).
• Levring (2018) reports that EU membership “would be backed by 55 percent of Danish voters” in a referendum (p. 3).

When you quote text that itself contains another quote, this is called a nested quotation or a quote within a quote. It may occur, for example, when quoting dialogue from a novel.

To distinguish this quote from the surrounding quote, you enclose it in single (instead of double) quotation marks (even if this involves changing the punctuation from the original text). Make sure to close both sets of quotation marks at the appropriate moments.

Note that if you only quote the nested quotation itself, and not the surrounding text, you can just use double quotation marks.

• Carraway introduces his narrative by quoting his father: “ “ Whenever you feel like criticizing anyone, ” he told me, “ just remember that all the people in this world haven’t had the advantages that you’ve had ” ” (Fitzgerald 1).
• Carraway introduces his narrative by quoting his father: “‘Whenever you feel like criticizing anyone,’ he told me, ‘just remember that all the people in this world haven’t had the advantages that you’ve had ” (Fitzgerald 1).
• Carraway introduces his narrative by quoting his father: “‘Whenever you feel like criticizing anyone,’ he told me, ‘just remember that all the people in this world haven’t had the advantages that you’ve had’” (Fitzgerald 1).
• Carraway begins by quoting his father’s invocation to “remember that all the people in this world haven’t had the advantages that you’ve had” (Fitzgerald 1).

Note:  When the quoted text in the source comes from another source, it’s best to just find that original source in order to quote it directly. If you can’t find the original source, you can instead cite it indirectly .

Often, incorporating a quote smoothly into your text requires you to make some changes to the original text. It’s fine to do this, as long as you clearly mark the changes you’ve made to the quote.

Shortening a quote

If some parts of a passage are redundant or irrelevant, you can shorten the quote by removing words, phrases, or sentences and replacing them with an ellipsis (…). Put a space before and after the ellipsis.

Be careful that removing the words doesn’t change the meaning. The ellipsis indicates that some text has been removed, but the shortened quote should still accurately represent the author’s point.

Altering a quote

You can add or replace words in a quote when necessary. This might be because the original text doesn’t fit grammatically with your sentence (e.g., it’s in a different verb tense), or because extra information is needed to clarify the quote’s meaning.

Use brackets to distinguish words that you have added from words that were present in the original text.

The Latin term “ sic ” is used to indicate a (factual or grammatical) mistake in a quotation. It shows the reader that the mistake is from the quoted material, not a typo of your own.

In some cases, it can be useful to italicize part of a quotation to add emphasis, showing the reader that this is the key part to pay attention to. Use the phrase “emphasis added” to show that the italics were not part of the original text.

You usually don’t need to use brackets to indicate minor changes to punctuation or capitalization made to ensure the quote fits the style of your text.

If you quote more than a few lines from a source, you must format it as a block quote . Instead of using quotation marks, you set the quote on a new line and indent it so that it forms a separate block of text.

Block quotes are cited just like regular quotes, except that if the quote ends with a period, the citation appears after the period.

To the end of his days Bilbo could never remember how he found himself outside, without a hat, a walking-stick or any money, or anything that he usually took when he went out; leaving his second breakfast half-finished and quite unwashed-up, pushing his keys into Gandalf’s hands, and running as fast as his furry feet could carry him down the lane, past the great Mill, across The Water, and then on for a mile or more. (16)

Avoid relying too heavily on quotes in academic writing . To integrate a source , it’s often best to paraphrase , which means putting the passage in your own words. This helps you integrate information smoothly and keeps your own voice dominant.

However, there are some situations in which quoting is more appropriate.

When focusing on language

If you want to comment on how the author uses language (for example, in literary analysis ), it’s necessary to quote so that the reader can see the exact passage you are referring to.

When giving evidence

To convince the reader of your argument, interpretation or position on a topic, it’s often helpful to include quotes that support your point. Quotes from primary sources (for example, interview transcripts or historical documents) are especially credible as evidence.

When presenting an author’s position or definition

When you’re referring to secondary sources such as scholarly books and journal articles, try to put others’ ideas in your own words when possible.

But if a passage does a great job at expressing, explaining, or defining something, and it would be very difficult to paraphrase without changing the meaning or losing the weakening the idea’s impact, it’s worth quoting directly.

A quote is an exact copy of someone else’s words, usually enclosed in quotation marks and credited to the original author or speaker.

In academic writing , there are three main situations where quoting is the best choice:

• To analyze the author’s language (e.g., in a literary analysis essay )
• To give evidence from primary sources
• To accurately present a precise definition or argument

Don’t overuse quotes; your own voice should be dominant. If you just want to provide information from a source, it’s usually better to paraphrase or summarize .

Every time you quote a source , you must include a correctly formatted in-text citation . This looks slightly different depending on the citation style .

For example, a direct quote in APA is cited like this: “This is a quote” (Streefkerk, 2020, p. 5).

Every in-text citation should also correspond to a full reference at the end of your paper.

A block quote is a long quote formatted as a separate “block” of text. Instead of using quotation marks , you place the quote on a new line, and indent the entire quote to mark it apart from your own words.

The rules for when to apply block quote formatting depend on the citation style:

• APA block quotes are 40 words or longer.
• MLA block quotes are more than 4 lines of prose or 3 lines of poetry.
• Chicago block quotes are longer than 100 words.

If you’re quoting from a text that paraphrases or summarizes other sources and cites them in parentheses , APA and Chicago both recommend retaining the citations as part of the quote. However, MLA recommends omitting citations within a quote:

• APA: Smith states that “the literature on this topic (Jones, 2015; Sill, 2019; Paulson, 2020) shows no clear consensus” (Smith, 2019, p. 4).
• MLA: Smith states that “the literature on this topic shows no clear consensus” (Smith, 2019, p. 4).

Footnote or endnote numbers that appear within quoted text should be omitted in all styles.

If you want to cite an indirect source (one you’ve only seen quoted in another source), either locate the original source or use the phrase “as cited in” in your citation.

In scientific subjects, the information itself is more important than how it was expressed, so quoting should generally be kept to a minimum. In the arts and humanities, however, well-chosen quotes are often essential to a good paper.

In social sciences, it varies. If your research is mainly quantitative , you won’t include many quotes, but if it’s more qualitative , you may need to quote from the data you collected .

As a general guideline, quotes should take up no more than 5–10% of your paper. If in doubt, check with your instructor or supervisor how much quoting is appropriate in your field.

Trump Escalates Anti-Immigrant Rhetoric With ‘Poisoning the Blood’ Comment

When asked about immigration in a recent interview, the former president used language with echoes of white supremacy and Hitler.

Former President Donald J. Trump said undocumented immigrants were “poisoning the blood of our country” in a recent interview, language with echoes of white supremacy and the racial hatreds of Adolf Hitler.

Mr. Trump made the remark in a 37-minute video interview with The National Pulse, a right-leaning website, that was posted last week. It drew broader scrutiny on Wednesday after the liberal MSNBC host Mehdi Hasan surfaced the quote in a post on X.

Other commentators went on to point out that Mr. Trump’s attack invoked a theme of Hitler’s autobiographical manifesto “Mein Kampf,” in which the Nazi Party leader railed about what he claimed was the impurity of immigrants, Jews and interracial couples.

In the interview , Mr. Trump was asked about immigration and the Southern border.

He replied: “Nobody has any idea where these people are coming from, and we know they come from prisons. We know they come from mental institutions and insane asylums. We know they’re terrorists. Nobody has ever seen anything like we’re witnessing right now. It is a very sad thing for our country. It’s poisoning the blood of our country. It’s so bad, and people are coming in with disease. People are coming in with every possible thing that you could have.”

At campaign rallies, Mr. Trump has repeated that leaders of unspecified South American countries were releasing patients from mental hospitals to send as migrants to the United States, but fact checkers have found no evidence for the claim .

Jonathan Greenblatt, the chief executive of the Anti-Defamation League, called Mr. Trump’s comments racist and xenophobic. “Insinuating that immigrants are ‘poisoning the blood of our country’ echoes nativist talking points and has the potential to cause real danger and violence,’’ Mr. Greenblatt said in a statement. “We have seen this kind of toxic rhetoric inspire real-world violence before in places like Pittsburgh and El Paso. It should have no place in our politics, period.”
