text citations for research paper

How To Cite a Research Paper: MLA, APA, and Chicago Style

• Posted on January 25, 2022

When you’re writing a research paper, you’ll use a variety of sources to find information. You might find that you end up using other people’s research papers as sources of information for your own work. You need to know how to cite a research paper properly.

Using text citations tells readers where you got your information, and help build a sense of trust, allowing the reader to feel confident that you haven’t falsified the information. You have to prove that you’ve done the research and found data to back up the claims you’re making.

Writing a paper without giving credit to people whose work you’re using is plagiarism. Unless you’re citing a direct quote you want to change the language enough, by putting the quote in your own words, so it sounds like original content. Quetext’s plagiarism checker  helps you search for similar content across the web so you can turn in a completely original paper.

Whether you’re submitting a research paper to school or for publication in a peer-reviewed journal, you’re required to cite your sources. Editors often reread the work of writers and researchers to ensure the information is factual. A teacher or professor will definitely check that your sources are accurate, so using tools like Quetext will help avoid unintentional plagiarism errors or wrongfully cited information.

Why Text Citations are Important

If you don’t have sources to back up your research, others might accuse you of spreading false information or plagiarism. Any journal publishing papers should verify what they’re printing, but ultimately, as the author, the buck stops with you.

In general, it’s a kindness to cite your sources. The people who created them did a lot of work, so it’s wrong to claim ownership of their ideas and information. But it’s also an ethical issue that can have major repercussions.

There have been cases where researchers  make up information  or falsify their sources and must face the consequences. People depend on factual information and don’t react well when they realize you lied to them or falsely paraphrase information.

That’s why it’s common knowledge to write a well-researched paper with text citations. If anyone claims your information is incorrect, you can point them to the source where you found the data. This doesn’t guarantee that the information you cited is correct, but you’ll be able to provide readers with a source of where you gathered your information.

When you’re citing other people’s research papers, make sure the source is legitimate. You should only use peer-reviewed journals so you know the article has gone through edits and fact-checking. Something identified as a research paper that is only on a blog or message board isn’t always a reliable source.

Many students like to use  Wikipedia  because there’s so much information available from one source. However, Wikipedia allows users to edit the information. What you read in a specific entry might not be true. It’s best to scroll down to the works cited and go to the original source yourself. If you can’t find a reliable, original source for the information, you shouldn’t use it.

Using the Various Citation Styles

The information used in any citation is basically the same across each style guide. The formatting and order of some elements may vary, so it’s important to know the difference between Modern Language Association (MLA), American Psychological Association (APA), and Chicago Styles.

The style you use depends on what type of writing you’re doing. All will use these basic elements in some form or another:

Source name

Volume and edition

Publication date

Page numbers

Publisher name

City and country of the publisher

URL and DOI for web pages and digital sources

The date you accessed the material

In addition to a reference list at the end of your work, you’ll also use in-text citations. Whenever you reference an idea or data that isn’t yours, you cite it. Each style has different types of in-text citations as well. Read on to find out about each citation format.

You’ll likely use the  MLA citation guide  if you’re writing papers in the humanities, such as for language arts, literary criticism, cultural studies, and more. The current edition of the MLA Handbook is the ninth because the style constantly evolves. As new technology creates new potential sources, MLA adds information to help students and researchers cite everything correctly.

The MLA Handbook has instructions on how to cite song lyrics, social media posts, and digital images, along with all of the standard research outlets. The book also gives detailed information on how to cite a research paper.

The MLA Handbook includes information about how to format your reference page. Use a 12-pt standard font like Times New Roman, so the text in italics is clearly different from the regular font. Center the title, Works Cited, at the top of the page. Your last name and page number are in the top right corner, and the reference page always comes at the end of your document.

Alphabetize citations according to the last name of the author. Left-align the citations and double-space them with no extra lines between each entry. When a citation goes beyond a single line, use a hanging indent to format it correctly. This lets the reader know it’s still the same citation continuing on.

Now that you know the basic format for the Works Cited page read on to find out how to cite a research paper for inclusion on this list.

Citing a Research Paper in MLA Style

When you’re citing a research paper in MLA style, you start with the author’s full name, putting the last name of the author first, followed by the title of the research paper in quotation marks. Next comes the the title of the journal that published the paper in italics, followed by the volume number, issue number, and date of publication.

You’ll also include the page number since the paper is in a journal with many pages. If you found the source online, include the digital object identifier or DOI. The DOI is a way to give a document a permanent web address so people reading your work can easily find the source.

MLA format also asks you to include the date you accessed online materials. Doing so gives your reader more information about when you read the research if it changed since that date. Here is an example of a research paper citation in MLA style:

Writer, Maria. “My Research Paper.” Research Journal, vol 3, no. 4, 2020, pp. 7-9. doi:12.34/mfs.12.34. Accessed 13 March 2021.

If the work wasn’t published online, you could stop your citation after the page numbers.

Sometimes you might find research papers that aren’t published in a scholarly journal. You can still use those in your work, but the MLA citation will look different. You’ll still put the last name of the author first, but instead of putting the title of the research paper in quotation marks, you’ll put it in italics.

Here is an example of an unpublished research paper citation in MLA style:

Writer, Maria. My Research Paper. 2020, http://websiteused.com . Accessed 13 March 2021.

These two examples show you how to document the source on your Works Cited page. In-text citations look different.

In-Text Citations for a Research Paper in MLA Style

When you’re working with the MLA format, an in-text reference requires a parenthetical citation.

If you refer to someone else’s research in a sentence, either with a direct quote or by paraphrasing, you need to give that author credit. At the end of the sentence where you use the information, you’ll put the author’s information in parenthesis and then put the sentence’s ending punctuation.

You use the author’s last name and the page number where you found the information for in-text citations. Then anyone reading your work can go to your Works Cited page, find the entry by the author’s last name, and access the document themselves. The page number directs them to where you got the specific information, so they don’t have to read the whole paper to find it. Here is an example of an in-text citation in MLA style:

Over 80% of the city’s garbage ended up in the ocean (Writer, 8).

You might mention the author’s name in your sentence. In that case, the parenthetical citation only needs to have the page numbers for reference. Here is an example:

According to Maria Writer, over 80% of the city’s garbage went into the ocean (8).

Researchers in the social science field, like sociology, anthropology, and psychology, use the  APA style  in their work. Like the MLA Handbook, the Publication Manual of the American Psychological Association has gone through changes over the years. It’s currently on the 7th edition.

In addition to helping you understand how to cite research, the Publication Manual of the American Psychological Association has information about how to format your paper to include tables, figures, and headings that often accompany scientific journal articles.

The Publication Manual of the American Psychological Association also tells you how to format your reference page. In MLA style, this is the Works Cited page. For APA style, it’s either the Reference List or Reference Page.

This page uses the same font style as the rest of the paper but starts on its own page with a number in the top right corner. The title of the page is bold and centered at the top and should simply read “References.”

List citations in alphabetical order by author’s last name regardless of the type of source. Each citation is double-spaced and has a hanging indent if it goes beyond one line.

Now that you understand how to properly format your APA reference page, learn how to cite a research paper to include on the list.

Citing a Research Paper in APA Style

When you use a research paper in your work, you need to include it on your APA references page at the end of your document.

An APA citation includes the same information as the MLA format but in a different order. The citation starts with the author’s last name but only uses their first initial. Then comes the year of publication in parenthesis.

The paper’s title follows, then the title of the journal in italics. You also include the journal volume, issue number, and page numbers. As with MLA citations, include a DOI if you found the research paper online. Here is an example of a published research paper cited in APA format:

Writer, M. (2020). My Research Paper. Research Journal, 3(4), 7-9. doi:12.34/mfs.12.34

If the paper isn’t published in a journal, you can still use it in your work with a proper citation. Here is an example:

Writer, M. (2020). My Research Paper [PDF]. Retrieved from http://websiteused.com

In-Text Citations for a Research Paper in APA Style

In-text citations in the APA format differ from MLA style. You still put it in parenthesis, but you include different information. For APA parentheticals, include the author’s last name and the paper’s year of publication. This method applies when you’re summarizing or paraphrasing the author’s idea. Here is an example of an in-text citation for a research paper in APA style:

Over 80% of the city’s garbage went into the ocean (Writer, 2020).

If you’re using a direct quote from the work you need to include the page number so the reader can find the quotation. Here is an example:

Maria Writer said, “Over 80% of the city’s garbage is going into the ocean” (2020, p. 8).

Chicago Style

Chicago Style  got its name from the University of Chicago, where the style originated. Writers use this format for works in the field of history, but you can also use it for the sciences, social sciences, and humanities.

MLA style has a Works Cited page, APA has References, and Chicago Style differs because it includes a Bibliography. The page comes at the end of your work with a page number in the top right corner. The title, “Bibliography,” is bold and centered at the top.

You will single-space your citations, but you’ll add an extra line between each entry. As with the other reference pages, you’ll left-align the work and use a hanging indent when a citation continues onto a second line.

Having an overview of how to format the bibliography will help you understand the citation styles for a research paper.

Citing a Research Paper in Chicago Style

Citations in Chicago Style are a mix of MLA and APA formats. It’s easiest to follow this template:

Writer, Maria. 2020. “My Research Paper.” Research Journal 3 (4): 7-9. doi:12.34/mfs.12.34.

As with other styles, you can reference an unpublished research paper as a document. Here is an example:

Writer, Maria. 2020. My Research Paper. PDF. http://websiteused.com .

In both instances, if there are multiple authors for a paper, list the rest of the authors in normal format. For example:

Author, Alan, Stanley Sample, and Maria Writer. 2020. “My Research Paper.” Research Journal 3 (4): 7-9. doi:12.34/mfs.12.34.

In-Text Citations for a Research Paper in Chicago Style

An in-text citation in Chicago Style is much simpler than both MLA and APA formats. You only need to include the last name of the author and year of publication in parenthesis with no comma in between them. For example:

Almost 80% of the city’s garbage goes into the ocean (Writer 2020).

You’ll include the page number for specificity if you’re quoting the author. Here’s an example:

Maria Writer said, “Over 80% of the city’s garbage is going into the ocean” (2020, 8).

You can also use endnotes in Chicago Style. A citation refers the reader to your source, but an endnote includes a bit of an explanation of why you used it. The information included in an endnote would disrupt the flow of your paper, but it’s still something you want the reader to know.

Make Text Citations Easy

Knowing when you need to cite a source helps you manage your research. Anytime you find information that you’re going to paraphrase, summarize, or quote in your work, you need to cite the source. The full citation will go on your reference page, but you’ll need an in-text citation where you use the information in your paper.

When you’re stating something that is  common knowledge , there’s no need to make a citation. Common knowledge is something that your reader would believe without needing proof. You can check if something is common knowledge by searching for it and finding it mentioned, without a citation, in at least five sources.

Once you learn the basics about citing a research paper in MLA, APA, and Chicago Styles, you’ll feel more confident in your work. The important thing is to pay attention to small details, like capitalization, italics and the use of abbreviations. But there’s no need to do it all on your own—Quetext has a  citation assistant  waiting to help. Give Quetext citation generator a try on your next project.

APA In-Text Citations for Research Writing

Why Use In-Text Citations?

When writing a journal article, literature review, convention paper, or any other academic document, authors must include in-text citations whenever they refer to, summarize, paraphrase, or quote from another source. In addition, every time a work is cited within a paper (in APA style, a parenthetical citation), a corresponding entry must be included in the reference list.

How to Cite a Research Paper Using In-Text Citations

The rationale behind citing other people’s publications in your own manuscript is that you want to avoid intellectual dishonesty by giving credit to whoever reported a finding first or invented a specific technique. This is not only an ethical question, as being “sloppy” with your sources can easily be considered plagiarism (and even self-plagiarism , if you fail to refer to your own work), which can have legal consequences and damage your reputation.

General rules for what information should be provided when citing sources in a research paper vary across fields and depend on the type of source (e.g., books, journal articles, patents, conference proceedings, websites, etc.). We are not going into such differences here but will focus on the correct way of referencing other people’s research in your own paper according to one of the most common styles used to cite sources within the social sciences and in several other academic disciplines , that is, APA (American Psychological Association) style .

In research papers, in-text citations are most commonly used in the Introduction and Discussion Results sections. The following guidelines and examples are taken from the APA Publication Manual, 6th edition, 2nd printing , which details rules and application of APA style in research papers, including in-text citations, endnotes/footnotes, and references. For more information, consult the APA Style Manual website .

This resource provides detailed guidelines for citing sources in your paper and includes examples of in-text citations for reference by research authors. Before submitting your manuscript to a journal or publisher, be sure to use our free APA citation generator for your references and in-text citations.

APA Citation Rules: The Basics

Order and structure of in-text citation content.

When using APA format, follow the “author-date” method of in-text citation. Write the author’s last name and publication year for the source in parentheses and separate these pieces of information with a comma.

When referring to external work or referencing an entire work but not directly quoting the material, you only need to make a reference to the author and year of publication and not the page number in your citation.

The results of the first enzyme study (Chen et al., 2014) revealed several relationships.

If you mention the name of the author of the work in the sentence or earlier in the paragraph, you only need to include the year of publication in the citation.

Chen (2014) discusses several relationships revealed in this study.

Verb tense used in referring to other works

APA style requires authors to use past tense or present perfect tense (NOT present tense) when using signal phrases to refer to or discuss previous research (have a look at this article for more details on the correct tenses for different parts of a research paper ).

Radnitz (1995) found… / Radnitz (1995) has found…

Placement of in-text citations in the sentence (no quotation)

When referring to a specific work or works, place the citation (publication date only) directly after the author of the study referenced.

Klinge and Rogers (2010) found that mirroring is instrumental in developments of performative gender roles.

When giving information that reflects the results or implications of previous work, place the citation (author and publication date) at the end of the sentence.

Mirroring has been found to be instrumental in the development of performative gender roles (Klinge and Rogers, 2010).

Capitalization

Always capitalize author names and initials in in-text citations.

(r. kazinsky, 2014)    (R. Kazinsky, 2014)

In-Text Citation Rules for Short Quotations

When quoting directly from a work, include the author, publication year, and page number of the reference (preceded by “p.”).

Method 1 : Introduce the quotation with a signal phrase that includes the author’s last name; the publication year will follow in parentheses. Include the page number in parentheses at the end of the quoted text. Note that the quotation marks surround the text only, and not the parenthetical citation.

According to Khan (1976), “Graduate students tend to apply more diverse methods during their first two years of research” (p. 45). Khan (1976) noted that “graduate students tend to apply more diverse methods during their first two years of research” (p. 45), a fact that has profound implications for research departments.

Method 2 : If the author is absent in the signal phrase, include the author’s last name, the publication year, and the page number together in parentheses after the quoted text.

Researchers noted that “graduate students tend to apply more diverse methods during their first two years of research” (Khan, 1976, p. 45), but they did not offer a suggestion as to the cause.

In-text Citation Rules for Long Quotations

Long direct quotations are those with at least 40 words of quoted text in a row. Long quotes should be placed in a separate block of lines without quotation marks, similar to creating a new paragraph. Begin the quotation on a new line and indent 0.5in/1.27cm from the left margin. Type the entire quotation within these new margins using double-spacing. Include the parenthetical citation after the final punctuation mark.

Khan’s (1976) study found the following: Graduate students tend to apply more diverse methods during their first two years of research, especially when conducting research in teams of three or fewer with no senior researchers    present. This tendency could be attributed to either a misunderstanding of correct methodology or to a feeling of freedom to explore different approaches that the researchers have yet to employ. (p. 45)

Summarizing and Paraphrasing Other Works

When  paraphrasing another work , you only need to cite the author and year of publication in your in-text citation. It may be a good idea to include the page number as well if the paraphrased information is located on a specific page of the original text. APA guidelines encourage this inclusion but do not require it.

According to Khan (1976), new researchers tend to use more diverse methodologies. New researchers tend to use more diverse methodologies (Khan, 1976, p. 45).

Common Signal Phrases for Introducing External Works

• According to Johnson (publication year)…
• As Johnson (publication year) has noted…
• Johnson and Smith (publication year) contend that…
• As Johnson’s (2011) study revealed…

Citing Works by Multiple Authors/Editors

When making an in-text citation of works by multiple authors, there are specific rules to follow depending on the number of authors of a publication and the number of times you cite the same works.

Citing Multiple Works in One In-text Citation

When citing more than one source in the same in-text citation, list all sources in the standard way and separate them with a semi-colon. List the sources alphabetically (by author’s last name or by title if no author is given) in the order they appear in the reference list.

(Marsh, 1997; Johnson, 2002). (Kazinsky, 2017; “Three Different Roads,”  2013).

Citing Works by the Same Author with the Same Publication Year

When citing two or more sources with the same author and year of publication, assign lowercase letters directly after the year of publication (a, b, c) according to the alphabetical order of titles. You will use the same alphabetical designations in your in-text citations that you do in your reference list.

The incidence of West Nile virus in Florida increased between 2002 and 2004 (Dickens, 2014a). According to Dickens (2014b), “these viral infections were precipitated by record levels of rainfall around the peninsula” (p. 150).

Citing a Work Quoted in another Source

Work quoted or paraphrased in another text is called a “secondary source.” While in your reference list you must cite the primary source as well, in your in-text citation you will add the words “as cited in” followed by the secondary source. For example, if a review article by Franklin you are citing includes a useful quote by Adams that supports your paper, your in-text citation would look like this:

According to a study by Adams (as cited in Franklin, 2016), 25% of all US federal prisoners have been diagnosed with some form of social disorder. Adams (as cited in Franklin) contends that this statistic “reflects the dehumanizing conditions of most federal institutions” (p. 76).

Citing Web Pages

Entire website.

When citing an entire website (with no specific webpage or article given), simply provide the title and web address within the text of your paper. No citation is needed in the References.

The American Psychological Association includes detailed information on how to apply APA citation (http://www.apa.org).

Webpage with author(s)

A webpage with an individual author or authors should be cited in the same way as other texts, with the name or names written first, followed by the publication year.

There were 523 new cases reported in 2011 alone (Kristoff, 2012).

Webpage with a group author

Treat group authors as individual authors in in-text citations, but instead of the author’s last name, include the name of the group.

Claustrophobia afflicts one in five Britons (The Surrey Group, 2003).

Webpage with missing information

Even when some central information is missing from a website (e.g., no author, date, or webpage title), you may still cite it as a source if you use the correct formatting. For information on how to cite a website with missing information, visit the APA Style Blog post on  Missing Pieces .

Citing social media sources

How to Cite a Research Paper in Each Research Paper Format

Dissertations, thesis, and all kinds of academic papers will need to be cited using citation styles, such as APA, MLA, or Chicago. Citing academic papers properly are done to counteract plagiarism. These citing formats are used to recognize related literary pieces and to mention references used. You should study various citing styles and research paper well before producing essays or any other pieces of academic writing. In this article, our term paper writers have prepared information on how to format research papers as well as how to properly reference academic papers.

APA Research Paper Format

APA (American Psychological Association) research paper format is often used in papers related to psychology and social sciences. In this citation, there is a general format in referencing through endnotes/footnotes, in-text, and reference pages. Academic papers in APA citation has general writing guidelines.

Papers should be typed, double-spaced on standard-sized paper (8.5" x 11") with 1" margins on all sides. You should use a clear font that is highly readable. APA recommends using 12 pt. Times New Roman font. Include a page header at the top of every page. To create a page header, insert page numbers flush right. Then type the title of your paper in the header flush left using all capital letters. The page header is a shortened version of your paper's title and cannot exceed 50 characters including spacing and punctuation.

Talking about how to write a research paper in APA format, your APA paper should have four major sections :

Be sure to read about how to write an essay format . In article, we talked about the differences between formats.

How to Cite a Research Paper in APA

There are specific rules to follow when citing a research paper in APA. The following are the specific formats to follow:

• Book: Author, A.A.. (Year of Publication). The Title of work. Publisher City, State: Publisher.
• Example : Finney, J. (1970). Time and again. New York, NY: Simon and Schuster.
• Magazine: Author, A.A.. (Year, a month of Publication). Article title. Magazine Title, Volume(Issue), pp.-pp.
• Example : Tumulty, K. (2006, April). Should they stay or should they go? Time, 167(15), 3-40.
• Newspaper: Author, A.A.. (Year, Month Date of Publication). Article title. Magazine Title, pp. xx-xx. Rosenberg, G. (1997, March 31). An electronic discovery proves an effective legal weapon.The New York Times, p. D5.
• Website: Author, A.A.. (Year, Month Date of Publication). Article title. Retrieved from URL
• Example : Simmons, B. (2015, January 9). The tale of two Flaccos. Retrieved from {link}

These citing formats are used to recognize related literary pieces and to mention references used. You don't need to cite information about yourself or your own thoughts. For example, when listing education on resume you don't need any citations. However, you should study various citing styles and research well before producing any other piece of academic writing.

MLA Research Paper Format

MLA (Modern Language Association) format format is commonly used in liberal arts and humanities. Let’s talk a bit about how to write a research paper in MLA format. This format has principles rather than a set of specific rules to be followed. Papers in MLA format provides a process of documentation.

MLA recommends using Times New Roman font in size 12. The entire paper should be double spaced with 1-inch margins on all sides. Tab once to indent paragraphs (½ inch). Your last name and a page number should be inserted on the upper right-hand corner of the first page.

How to Cite a Research Paper in MLA Format

The following are formats to follow in citing research paper in MLA format:

• Book: Last Name, First Name. Book Title. Publisher City: Publisher Name, Year Published. Medium.
• Example : Smith, John. The Sample Book. Pittsburgh: BibMe, 2008. Print.
• Magazine: Last Name, First Name. “Article Title.” Magazine Name Publication Date: Page Numbers. Medium.
• Example : Smith, John. “Obama inaugurated as President.” Time 21 Jan. 2009: 21-23. Print.
• Newspaper: Last Name, First Name. “Article Title.” Newspaper Name Publication Date: Page Numbers. Medium.
• Example : Smith, John. “Steelers win Super Bowl XLIII.” Pittsburgh Post-Gazette 2 Feb. 2009: 4-6. Print.
• Website: Last Name, First Name. “Page Title.” Website Title.Sponsoring Institution/Publisher. Publication Date: Page Numbers. Medium.
• Example : Smith, John. “Obama inaugurated as President.” CNN.com. Cable News Network, 21 Jan. 2009. Web. 1 Feb. 2009.

Research Paper in Chicago Style

The Chicago style of citing is commonly used in humanities. It requires writers to cite sources in endnotes or footnotes. This citation provides the author with an avenue to express accountability and credibility to related literature or references used in written material. It helps an academic writer provide quotations in a research paper, as well as being commonly used for book bibliographies.

Look at our movie review example and try to determine what format it is written in.

How to Cite a Research Paper in Chicago Style

What Is Cite This For Me's Citation Generator?

Cite This For Me’s open-access generator is an automated citation machine that turns any of your sources into citations in just a click. Using a citation generator helps students to integrate referencing into their research and writing routine; turning a time-consuming ordeal into a simple task.

A citation machine is essentially a works cited generator that accesses information from across the web, drawing the relevant information into a fully-formatted bibliography that clearly presents all of the sources that have contributed to your work.

If you don’t know how to cite correctly, or have a fast-approaching deadline, Cite This For Me’s accurate and intuitive citation machine will lend you the confidence to realise your full academic potential. In order to get a grade that reflects all your hard work, your citations must be accurate and complete. Using a citation maker to create your references not only saves you time but also ensures that you don’t lose valuable marks on your assignment.

Not sure how to format your citations, what citations are, or just want to find out more about Cite This For Me’s citation machine? This guide outlines everything you need to know to equip yourself with the know-how and confidence to research and cite a wide range of diverse sources in your work.

Why Do I Need To Cite?

Simply put, referencing is the citing of sources used in essays, articles, research, conferences etc. When another source contributes to your work, you have to give the original owner the appropriate credit. After all, you wouldn’t steal someone else’s possessions so why would you steal their ideas?

Any factual material or ideas you take from another source must be acknowledged in a reference, unless it is common knowledge (e.g. President Kennedy was killed in 1963). Failing to credit all of your sources, even when you’ve paraphrased or completely reworded the information, is plagiarism. Plagiarizing will result in disciplinary action, which can range from losing precious points on your assignment to expulsion from your university.

What’s more, attributing your research infuses credibility and authority into your work, both by supporting your own ideas and by demonstrating the breadth of your research. For many students, crediting sources can be a confusing and tedious process, but it’s a surefire way to improve the quality of your work so it’s essential to get it right. Luckily for you, using Cite This For Me’s citation machine makes creating accurate references easier than ever, leaving more time for you to excel in your studies.

In summary, the referencing process serves three main functions:

• To validate the statements and conclusions in your work by providing directions to other sound sources that support and verify them.
• To help your readers locate, read and check your sources, as well as establishing their contribution to your work.
• To give credit to the original author and hence avoid committing intellectual property theft (known as ‘plagiarism’ in academia).

How Do I Cite My Sources With The Cite This For Me's Citation Machine?

Cite This For Me’s citation generator is the most accurate citation machine available, so whether you’re not sure how to format in-text citations or are looking for a foolproof solution to automate a fully-formatted works cited list, this citation machine will solve all of your referencing needs.

Referencing your source material doesn’t just prevent you from losing valuable marks for plagiarism, it also provides all of the information to help your reader find for themselves the book, article, or other item you are citing. The accessible interface of this citation builder makes it easy for you to identify the source you have used – simply enter its unique identifier into the citation machine search bar. If this information is not available you can search for the title or author instead, and then select from the search results that appear below the citation generator.

The good news is that by using tools such as Cite This For Me, which help you work smarter, you don’t need to limit your research to sources that are traditional to cite. In fact, there are no limits to what you can reference, whether it be a YouTube video, website or a tweet.

To use the works cited generator, simply:

• Select from APA, MLA, Chicago, ASA, IEEE and AMA * styles.
• Choose the type of source you would like to cite (e.g. website, book, journal, video).
• Enter the URL , DOI , ISBN , title, or other unique source information into the citation generator to find your source.
• Click the ‘Cite’ button on the citation machine.
• Copy your new reference from the citation generator into your bibliography or works cited list.
• Repeat for each source that has contributed to your work.

*If you require another referencing style for your paper, essay or other academic work, you can select from over 7,500 styles.

Once you have created your Cite This For Me account you will be able to use the citation machine to generate multiple references and save them into a project. Use the highly-rated iOS or Android apps to create references in a flash with your smartphone camera, export your complete bibliography in one go, and much more.

What Will The Citation Machine Create For Me?

Cite This For Me’s citation maker will generate your reference in two parts; an in-text citation and a full reference to be copied straight into your work.

The citation machine will auto-generate the correct formatting for your works cited list or bibliography depending on your chosen style. For instance, if you select a parenthetical style on the citation machine it will generate an in-text citation in parentheses, along with a full reference to slot into your bibliography. Likewise, if the citation generator is set to a footnote style then it will create a fully-formatted reference for your reference page and bibliography, as well as a corresponding footnote to insert at the bottom of the page containing the relevant source.

Parenthetical referencing examples:

In-text example: A nation has been defined as an imagined community (Anderson, 2006).* Alternative format: Anderson (2006) defined a nation as an imagined community.

*The citation machine will create your references in the first style, but this should be edited if the author’s name already appears in the text.

Bibliography / Works Cited list example: Anderson, B. (2006). Imagined Communities. London: Verso.

What Are Citation Styles?

A citation style is a set of rules that you, as an academic writer, must follow to ensure the quality and relevance of your work. There are thousands of styles that are used in different academic institutions around the world, but in the US the most common are APA, MLA and Chicago.

The style you need to use will depend on the preference of your professor, discipline or academic institution – so if you’re unsure which style you should be using, consult your department and follow their guidelines exactly, as this is what you’ll be evaluated on when it comes to grading.

Referencing isn’t just there to guard against plagiarism – presenting your research in a clear and consistent way eases the reader’s comprehension. Each style has a different set of rules for both page formatting and referencing. Be sure to adhere to formatting rules such as font type, font size and line spacing to ensure that your work is easily legible. Furthermore, if your work is published as part of an anthology or collected works, each entry will need to be presented in the same style to maintain uniformity throughout. It is important to make sure that you don’t jump from one style to another, so follow the rules carefully to ensure your reference page and bibliography are both accurate and complete.

If you need a hand with your referencing then why not try Cite This For Me’s citation builder? It’s the quickest and easiest way to reference any source, in any style. The citation generator above will create your references in MLA format style as standard, but this powerful citation machine can generate fully-formatted references in thousands of the widely used global college styles – including individual university variations of each style. So, whether your subject requires you to use the APA citation , or your professor has asked you to adopt the Chicago style citation so that your work includes numbered footnotes, we’re sure to have the style you need. Cite This For Me also offers a citation machine and helpful formatting guide for styles such as ASA , IEEE or AMA . To access all of them, simply create your free account and search for your specific style.

How Do I Format A Works Cited List Or Bibliography?

Drawing on a wide range of sources greatly enhances the quality of your work, and reading above and beyond your recommended reading list – and then using these sources to support your own thesis – is an excellent way to impress your reader. A clearly presented works cited list or bibliography demonstrates the lengths you have gone to in researching your chosen topic.

Typically, a works cited list starts on a new page at the end of the main body of text and includes a complete list of the sources you have actually cited in your paper. This list should contain all the information needed for the reader to locate the original source of the information, quote or statistic that directly contributed to your work. On the other hand, a bibliography is a comprehensive list of all the material you may have consulted throughout your research and writing process. Both provide the necessary information for readers to retrieve and check the sources cited in your work.

Each style’s guidelines will define the terminology of ‘ works cited ’ and ‘ bibliography ’, as well as providing formatting guidelines for font, line spacing and page indentations. In addition, it will instruct you on how to order your works cited list or bibliography – this will usually be either alphabetical or chronological (meaning the order that these sources appear in your work). Before submitting your work, be sure to check that you have formatted your whole paper – including your reference page and bibliography – according to your style’s formatting guidelines.

Sounds complicated? Referencing has never been so easy; Cite This For Me’s citation machine will automatically generate fully-formatted references for your works cited page or bibliography in your chosen style. Sign in to your Cite This For Me account to save and export your bibliography straight into Microsoft Word, Evernote, EndNote and more. If that sounds like too much work.

How Do Citations Actually Work?

Although the citation generator will create your bibliography and works cited list for you in record time, it is still useful to understand how this system works behind the scenes. Understanding how a citation machine actually generates references will greatly increase the quality of your work.

As well as saving you time with its citation maker, Cite This For Me provides the learning resources to help you fully understand the citing process and the benefits of adopting great referencing standards.

The referencing process:

• Find a book, journal, website or other source that will contribute to your work.
• Save the quote, image, data or other information that you will use in your work.
• Save the source information that enables you to find it again (i.e. URL, ISBN, DOI etc.).
• Format the source information into a reference.
• Copy and paste the reference into the body of the text.
• Repeat for each source that contributes to your work.
• Export or copy and paste the fully-formatted reference into your bibliography.

How to Do In-Text Citations in a Research Paper

How to Check a Paper Citation

Proper in-text citations within a research or term paper can make the difference between a passing and failing grade, as failure to provide proper in-text citations can lead to a charge of plagiarism. Using in-text citations helps tell the reader where the information you are discussing originated. In other words, it gives credit where credit is due for the origination of ideas that you are coordinating within the text of your paper. Even if you are taking all of your information from a single source, in-text citations are still a very important element of your paper and should not be overlooked.

Use an in-text citation whenever you are discussing an idea that is not your own. Any information, including images, statistics, data, ideas, quotes or paraphrases, that you use from another source must be cited within the text of your paper.

Place the in-text citation within the text of your paper after the information that the citation refers to. In most cases the citation will go at the end of the sentence, but in some cases where you are discussing a concept in more than one sentence, you will put the citation after a set of sentences that are all discussing the same idea or concept. Additionally, sometimes you will have more than one idea within a sentence, and each idea will come from a separate source. When this is the case, you will have multiple in-text citations within the sentence.

Review the guidelines of the particular type of writing style that you have been requested to use in writing your paper to determine the proper format for your in-text citations. Some of the most common citation methods include APA, MLA and Chicago. An example of an APA in-text citation would look like this: Jones and Jones (2007) discovered the principle of excitation. Alternatively, it may look like this: Researchers have recently discovered the principle of excitation (Jones & Jones, 2007).

Ensure that each in-text citation matches up with a full citation placed in your reference list, which may be termed a bibliography or works cited list. This allows a reader to look at a citation within the text of your paper and then refer to the reference list to find the full details of the citation so that she can investigate the topic further on her own.

• Ask your professor what style of citations he would prefer you to use when writing your paper.
• In general, the punctuation for your sentence will go after the in-text citation.
• Computer programs are available to handle your in-text citations and reference lists for you. These programs will ensure that your citations are always formatted properly and will allow you to select the proper citation style.
• Without proper citation, you can inadvertently plagiarize another person's work.

Question   What are the temporal trends in gender-affirming surgery (GAS) in the US?

Findings   In this cohort study of 48 019 patients, GAS increased significantly, nearly tripling from 2016 to 2019. Breast and chest surgery was the most common class of procedures performed overall; genital reconstructive procedures were more common among older individuals.

Meaning   These findings suggest that there will be a greater need for clinicians knowledgeable in the care of transgender individuals with the requisite expertise to perform gender-affirming procedures.

Importance   While changes in federal and state laws mandating coverage of gender-affirming surgery (GAS) may have led to an increase in the number of annual cases, comprehensive data describing trends in both inpatient and outpatient procedures are limited.

Objective   To examine trends in inpatient and outpatient GAS procedures in the US and to explore the temporal trends in the types of GAS performed across age groups.

Design, Setting, and Participants   This cohort study includes data from 2016 to 2020 in the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample. Patients with diagnosis codes for gender identity disorder, transsexualism, or a personal history of sex reassignment were identified, and the performance of GAS, including breast and chest procedures, genital reconstructive procedures, and other facial and cosmetic surgical procedures, were identified.

Main Outcome Measures   Weighted estimates of the annual number of inpatient and outpatient procedures performed and the distribution of each class of procedure overall and by age were analyzed.

Results   A total of 48 019 patients who underwent GAS were identified, including 25 099 (52.3%) who were aged 19 to 30 years. The most common procedures were breast and chest procedures, which occurred in 27 187 patients (56.6%), followed by genital reconstruction (16 872 [35.1%]) and other facial and cosmetic procedures (6669 [13.9%]). The absolute number of GAS procedures rose from 4552 in 2016 to a peak of 13 011 in 2019 and then declined slightly to 12 818 in 2020. Overall, 25 099 patients (52.3%) were aged 19 to 30 years, 10 476 (21.8%) were aged 31 to 40, and 3678 (7.7%) were aged12 to 18 years. When stratified by the type of procedure performed, breast and chest procedures made up a greater percentage of the surgical interventions in younger patients, while genital surgical procedures were greater in older patients.

Conclusions and Relevance   Performance of GAS has increased substantially in the US. Breast and chest surgery was the most common group of procedures performed. The number of genital surgical procedures performed increased with increasing age.

Gender dysphoria is characterized as an incongruence between an individual’s experienced or expressed gender and the gender that was assigned at birth. 1 Transgender individuals may pursue multiple treatments, including behavioral therapy, hormonal therapy, and gender-affirming surgery (GAS). 2 GAS encompasses a variety of procedures that align an individual patient’s gender identity with their physical appearance. 2 - 4

While numerous surgical interventions can be considered GAS, the procedures have been broadly classified as breast and chest surgical procedures, facial and cosmetic interventions, and genital reconstructive surgery. 2 , 4 Prior studies 2 - 7 have shown that GAS is associated with improved quality of life, high rates of satisfaction, and a reduction in gender dysphoria. Furthermore, some studies have reported that GAS is associated with decreased depression and anxiety. 8 Lastly, the procedures appear to be associated with acceptable morbidity and reasonable rates of perioperative complications. 2 , 4

Given the benefits of GAS, the performance of GAS in the US has increased over time. 9 The increase in GAS is likely due in part to federal and state laws requiring coverage of transition-related care, although actual insurance coverage of specific procedures is variable. 10 , 11 While prior work has shown that the use of inpatient GAS has increased, national estimates of inpatient and outpatient GAS are lacking. 9 This is important as many GAS procedures occur in ambulatory settings. We performed a population-based analysis to examine trends in GAS in the US and explored the temporal trends in the types of GAS performed across age groups.

To capture both inpatient and outpatient surgical procedures, we used data from the Nationwide Ambulatory Surgery Sample (NASS) and the National Inpatient Sample (NIS). NASS is an ambulatory surgery database and captures major ambulatory surgical procedures at nearly 2800 hospital-owned facilities from up to 35 states, approximating a 63% to 67% stratified sample of hospital-owned facilities. NIS comprehensively captures approximately 20% of inpatient hospital encounters from all community hospitals across 48 states participating in the Healthcare Cost and Utilization Project (HCUP), covering more than 97% of the US population. Both NIS and NASS contain weights that can be used to produce US population estimates. 12 , 13 Informed consent was waived because data sources contain deidentified data, and the study was deemed exempt by the Columbia University institutional review board. This cohort study followed the Strengthening the Reporting of Observational Studies in Epidemiology ( STROBE ) reporting guideline.

We selected patients of all ages with an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision ( ICD-10 ) diagnosis codes for gender identity disorder or transsexualism ( ICD-10 F64) or a personal history of sex reassignment ( ICD-10 Z87.890) from 2016 to 2020 (eTable in Supplement 1 ). We first examined all hospital (NIS) and ambulatory surgical (NASS) encounters for patients with these codes and then analyzed encounters for GAS within this cohort. GAS was identified using ICD-10 procedure codes and Common Procedural Terminology codes and classified as breast and chest procedures, genital reconstructive procedures, and other facial and cosmetic surgical procedures. 2 , 4 Breast and chest surgical procedures encompassed breast reconstruction, mammoplasty and mastopexy, or nipple reconstruction. Genital reconstructive procedures included any surgical intervention of the male or female genital tract. Other facial and cosmetic procedures included cosmetic facial procedures and other cosmetic procedures including hair removal or transplantation, liposuction, and collagen injections (eTable in Supplement 1 ). Patients might have undergone procedures from multiple different surgical groups. We measured the total number of procedures and the distribution of procedures within each procedural group.

Within the data sets, sex was based on patient self-report. The sex of patients in NIS who underwent inpatient surgery was classified as either male, female, missing, or inconsistent. The inconsistent classification denoted patients who underwent a procedure that was not consistent with the sex recorded on their medical record. Similar to prior analyses, patients in NIS with a sex variable not compatible with the procedure performed were classified as having undergone genital reconstructive surgery (GAS not otherwise specified). 9

Clinical variables in the analysis included patient clinical and demographic factors and hospital characteristics. Demographic characteristics included age at the time of surgery (12 to 18 years, 19 to 30 years, 31 to 40 years, 41 to 50 years, 51 to 60 years, 61 to 70 years, and older than 70 years), year of the procedure (2016-2020), and primary insurance coverage (private, Medicare, Medicaid, self-pay, and other). Race and ethnicity were only reported in NIS and were classified as White, Black, Hispanic and other. Race and ethnicity were considered in this study because prior studies have shown an association between race and GAS. The income status captured national quartiles of median household income based of a patient’s zip code and was recorded as less than 25% (low), 26% to 50% (medium-low), 51% to 75% (medium-high), and 76% or more (high). The Elixhauser Comorbidity Index was estimated for each patient based on the codes for common medical comorbidities and weighted for a final score. 14 Patients were classified as 0, 1, 2, or 3 or more. We separately reported coding for HIV and AIDS; substance abuse, including alcohol and drug abuse; and recorded mental health diagnoses, including depression and psychoses. Hospital characteristics included a composite of teaching status and location (rural, urban teaching, and urban nonteaching) and hospital region (Northeast, Midwest, South, and West). Hospital bed sizes were classified as small, medium, and large. The cutoffs were less than 100 (small), 100 to 299 (medium), and 300 or more (large) short-term acute care beds of the facilities from NASS and were varied based on region, urban-rural designation, and teaching status of the hospital from NIS. 8 Patients with missing data were classified as the unknown group and were included in the analysis.

National estimates of the number of GAS procedures among all hospital encounters for patients with gender identity disorder were derived using discharge or encounter weight provided by the databases. 15 The clinical and demographic characteristics of the patients undergoing GAS were reported descriptively. The number of encounters for gender identity disorder, the percentage of GAS procedures among those encounters, and the absolute number of each procedure performed over time were estimated. The difference by age group was examined and tested using Rao-Scott χ 2 test. All hypothesis tests were 2-sided, and P  < .05 was considered statistically significant. All analyses were conducted using SAS version 9.4 (SAS Institute Inc).

A total of 48 019 patients who underwent GAS were identified ( Table 1 ). Overall, 25 099 patients (52.3%) were aged 19 to 30 years, 10 476 (21.8%) were aged 31 to 40, and 3678 (7.7%) were aged 12 to 18 years. Private insurance coverage was most common in 29 064 patients (60.5%), while 12 127 (25.3%) were Medicaid recipients. Depression was reported in 7192 patients (15.0%). Most patients (42 467 [88.4%]) were treated at urban, teaching hospitals, and there was a disproportionate number of patients in the West (22 037 [45.9%]) and Northeast (12 396 [25.8%]). Within the cohort, 31 668 patients (65.9%) underwent 1 procedure while 13 415 (27.9%) underwent 2 procedures, and the remainder underwent multiple procedures concurrently ( Table 1 ).

The overall number of health system encounters for gender identity disorder rose from 13 855 in 2016 to 38 470 in 2020. Among encounters with a billing code for gender identity disorder, there was a consistent rise in the percentage that were for GAS from 4552 (32.9%) in 2016 to 13 011 (37.1%) in 2019, followed by a decline to 12 818 (33.3%) in 2020 ( Figure 1 and eFigure in Supplement 1 ). Among patients undergoing ambulatory surgical procedures, 37 394 (80.3%) of the surgical procedures included gender-affirming surgical procedures. For those with hospital admissions with gender identity disorder, 10 625 (11.8%) of admissions were for GAS.

Breast and chest procedures were most common and were performed for 27 187 patients (56.6%). Genital reconstruction was performed for 16 872 patients (35.1%), and other facial and cosmetic procedures for 6669 patients (13.9%) ( Table 2 ). The most common individual procedure was breast reconstruction in 21 244 (44.2%), while the most common genital reconstructive procedure was hysterectomy (4489 [9.3%]), followed by orchiectomy (3425 [7.1%]), and vaginoplasty (3381 [7.0%]). Among patients who underwent other facial and cosmetic procedures, liposuction (2945 [6.1%]) was most common, followed by rhinoplasty (2446 [5.1%]) and facial feminizing surgery and chin augmentation (1874 [3.9%]).

The absolute number of GAS procedures rose from 4552 in 2016 to a peak of 13 011 in 2019 and then declined slightly to 12 818 in 2020 ( Figure 1 ). Similar trends were noted for breast and chest surgical procedures as well as genital surgery, while the rate of other facial and cosmetic procedures increased consistently from 2016 to 2020. The distribution of the individual procedures performed in each class were largely similar across the years of analysis ( Table 3 ).

When stratified by age, patients 19 to 30 years had the greatest number of procedures, 25 099 ( Figure 2 ). There were 10 476 procedures performed in those aged 31 to 40 years and 4359 in those aged 41 to 50 years. Among patients younger than 19 years, 3678 GAS procedures were performed. GAS was less common in those cohorts older than 50 years. Overall, the greatest number of breast and chest surgical procedures, genital surgical procedures, and facial and other cosmetic surgical procedures were performed in patients aged 19 to 30 years.

When stratified by the type of procedure performed, breast and chest procedures made up the greatest percentage of the surgical interventions in younger patients while genital surgical procedures were greater in older patients ( Figure 2 ). Additionally, 3215 patients (87.4%) aged 12 to 18 years underwent GAS and had breast or chest procedures. This decreased to 16 067 patients (64.0%) in those aged 19 to 30 years, 4918 (46.9%) in those aged 31 to 40 years, and 1650 (37.9%) in patients aged 41 to 50 years ( P  < .001). In contrast, 405 patients (11.0%) aged 12 to 18 years underwent genital surgery. The percentage of patients who underwent genital surgery rose sequentially to 4423 (42.2%) in those aged 31 to 40 years, 1546 (52.3%) in those aged 51 to 60 years, and 742 (58.4%) in those aged 61 to 70 years ( P  < .001). The percentage of patients who underwent facial and other cosmetic surgical procedures rose with age from 9.5% in those aged 12 to 18 years to 20.6% in those aged 51 to 60 years, then gradually declined ( P  < .001). Figure 2 displays the absolute number of procedure classes performed by year stratified by age. The greatest magnitude of the decline in 2020 was in younger patients and for breast and chest procedures.

These findings suggest that the number of GAS procedures performed in the US has increased dramatically, nearly tripling from 2016 to 2019. Breast and chest surgery is the most common class of procedure performed while patients are most likely to undergo surgery between the ages of 19 and 30 years. The number of genital surgical procedures performed increased with increasing age.

Consistent with prior studies, we identified a remarkable increase in the number of GAS procedures performed over time. 9 , 16 A prior study examining national estimates of inpatient GAS procedures noted that the absolute number of procedures performed nearly doubled between 2000 to 2005 and from 2006 to 2011. In our analysis, the number of GAS procedures nearly tripled from 2016 to 2020. 9 , 17 Not unexpectedly, a large number of the procedures we captured were performed in the ambulatory setting, highlighting the need to capture both inpatient and outpatient procedures when analyzing data on trends. Like many prior studies, we noted a decrease in the number of procedures performed in 2020, likely reflective of the COVID-19 pandemic. 18 However, the decline in the number of procedures performed between 2019 and 2020 was relatively modest, particularly as these procedures are largely elective.

Analysis of procedure-specific trends by age revealed a number of important findings. First, GAS procedures were most common in patients aged 19 to 30 years. This is in line with prior work that demonstrated that most patients first experience gender dysphoria at a young age, with approximately three-quarters of patients reporting gender dysphoria by age 7 years. These patients subsequently lived for a mean of 23 years for transgender men and 27 years for transgender women before beginning gender transition treatments. 19 Our findings were also notable that GAS procedures were relatively uncommon in patients aged 18 years or younger. In our cohort, fewer than 1200 patients in this age group underwent GAS, even in the highest volume years. GAS in adolescents has been the focus of intense debate and led to legislative initiatives to limit access to these procedures in adolescents in several states. 20 , 21

Second, there was a marked difference in the distribution of procedures in the different age groups. Breast and chest procedures were more common in younger patients, while genital surgery was more frequent in older individuals. In our cohort of individuals aged 19 to 30 years, breast and chest procedures were twice as common as genital procedures. Genital surgery gradually increased with advancing age, and these procedures became the most common in patients older than 40 years. A prior study of patients with commercial insurance who underwent GAS noted that the mean age for mastectomy was 28 years, significantly lower than for hysterectomy at age 31 years, vaginoplasty at age 40 years, and orchiectomy at age 37 years. 16 These trends likely reflect the increased complexity of genital surgery compared with breast and chest surgery as well as the definitive nature of removal of the reproductive organs.

This study has limitations. First, there may be under-capture of both transgender individuals and GAS procedures. In both data sets analyzed, gender is based on self-report. NIS specifically makes notation of procedures that are considered inconsistent with a patient’s reported gender (eg, a male patient who underwent oophorectomy). Similar to prior work, we assumed that patients with a code for gender identity disorder or transsexualism along with a surgical procedure classified as inconsistent underwent GAS. 9 Second, we captured procedures commonly reported as GAS procedures; however, it is possible that some of these procedures were performed for other underlying indications or diseases rather than solely for gender affirmation. Third, our trends showed a significant increase in procedures through 2019, with a decline in 2020. The decline in services in 2020 is likely related to COVID-19 service alterations. Additionally, while we comprehensively captured inpatient and ambulatory surgical procedures in large, nationwide data sets, undoubtedly, a small number of procedures were performed in other settings; thus, our estimates may underrepresent the actual number of procedures performed each year in the US.

These data have important implications in providing an understanding of the use of services that can help inform care for transgender populations. The rapid rise in the performance of GAS suggests that there will be a greater need for clinicians knowledgeable in the care of transgender individuals and with the requisite expertise to perform GAS procedures. However, numerous reports have described the political considerations and challenges in the delivery of transgender care. 22 Despite many medical societies recognizing the necessity of gender-affirming care, several states have enacted legislation or policies that restrict gender-affirming care and services, particularly in adolescence. 20 , 21 These regulations are barriers for patients who seek gender-affirming care and provide legal and ethical challenges for clinicians. As the use of GAS increases, delivering equitable gender-affirming care in this complex landscape will remain a public health challenge.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6 th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association , (6 th ed., 2 nd printing).

Note:  This page reflects APA 6, which is now out of date. It will remain online until 2021, but will not be updated. The equivalent APA 7 page can be found here .

Reference citations in text are covered on pages 169-179 of the Publication Manual. What follows are some general guidelines for referring to the works of others in your essay.

Note:  On pages 65-66, the Publication Manual suggests that authors of research papers should use the past tense or present perfect tense for signal phrases that occur in the literature review and procedure descriptions (for example, Jones (1998) found or Jones (1998) has found ...). Contexts other than traditionally-structured research writing may permit the simple present tense (for example, Jones (1998)  finds ).

APA citation basics

When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, for example, (Jones, 1998), and a complete reference should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but NOT directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication and not the page number in your in-text reference. All sources that are cited in the text must appear in the reference list at the end of the paper.

In-text citation capitalization, quotes, and italics/underlining

• Always capitalize proper nouns, including author names and initials: D. Jones.

( Note: in your References list, only the first word of a title will be capitalized: Writing new media .)

• When capitalizing titles, capitalize both words in a hyphenated compound word: Natural-Born Cyborgs .
• Capitalize the first word after a dash or colon: "Defining Film Rhetoric: The Case of Hitchcock's Vertigo ."
• Italicize the titles of longer works such as books, edited collections, movies, television series, documentaries, or albums: The Closing of the American Mind ; The Wizard of Oz ; Friends .
• Put quotation marks around the titles of shorter works such as journal articles, articles from edited collections, television series episodes, and song titles: "Multimedia Narration: Constructing Possible Worlds;" "The One Where Chandler Can't Cry."

Short quotations

If you are directly quoting from a work, you will need to include the author, year of publication, and page number for the reference (preceded by "p."). Introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

According to Jones (1998), "Students often had difficulty using APA style, especially when it was their first time" (p. 199).

Jones (1998) found "students often had difficulty using APA style" (p. 199); what implications does this have for teachers?

If the author is not named in a signal phrase, place the author's last name, the year of publication, and the page number in parentheses after the quotation.

She stated, "Students often had difficulty using APA style" (Jones, 1998, p. 199), but she did not offer an explanation as to why.

Long quotations

Place direct quotations that are 40 words or longer in a free-standing block of typewritten lines and omit quotation marks. Start the quotation on a new line, indented 1/2 inch from the left margin, i.e., in the same place you would begin a new paragraph. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation 1/2 inch from the new margin. Maintain double-spacing throughout. The parenthetical citation should come after the closing punctuation mark.

Students often had difficulty using APA style, especially when it was their first time citing sources. This difficulty could be attributed to the fact that many students failed to purchase a style manual or to ask their teacher for help. (p. 199)

Summary or paraphrase

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference, but APA guidelines encourage you to also provide the page number (although it is not required).

According to Jones (1998), APA style is a difficult citation format for first-time learners.

APA style is a difficult citation format for first-time learners (Jones, 1998, p. 199).
