APA In-Text Citations for Research Writing

how to put in text citations in a research paper

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

Using In-text Citation

Include an in-text citation when you refer to, summarize, paraphrase, or quote from another source. For every in-text citation in your paper, there must be a corresponding entry in your reference list.

APA in-text citation style uses the author's last name and the year of publication, for example: (Field, 2005). For direct quotations, include the page number as well, for example: (Field, 2005, p. 14). For sources such as websites and e-books that have no page numbers , use a paragraph number, for example: (Field, 2005, para. 1). More information on direct quotation of sources without pagination is given on the APA Style and Grammar Guidelines web page.

Example paragraph with in-text citation

A few researchers in the linguistics field have developed training programs designed to improve native speakers' ability to understand accented speech (Derwing et al., 2002; Thomas, 2004). Their training techniques are based on the research described above indicating that comprehension improves with exposure to non-native speech.   Derwing et al. (2002) conducted their training with students preparing to be social workers, but note that other professionals who work with non-native speakers could benefit from a similar program.

Derwing, T. M., Rossiter, M. J., & Munro, M. J. (2002). Teaching native speakers to listen to foreign-accented speech.  Journal of Multilingual and Multicultural Development , 23 (4), 245-259.

Thomas, H. K. (2004).  Training strategies for improving listeners' comprehension of foreign-accented speech  (Doctoral dissertation). University of Colorado, Boulder.

Citing Web Pages In Text

Cite web pages in text as you would any other source, using the author and date if known. Keep in mind that the author may be an organization rather than a person. For sources with no author, use the title in place of an author.

For sources with no date use n.d. (for no date) in place of the year: (Smith, n.d.). For more information on citations for sources with no date or other missing information see the page on missing reference information on the APA Style and Grammar Guidelines web page. 

Below are examples of using in-text citation with web pages.

Web page with author:

General Guidelines

In-text references should immediately follow the title, word, or phrase to which they are directly relevant, rather than appearing at the end of long clauses or sentences. In-text references should always precede punctuation marks. Below are examples of using in-text citation.

Author's name in parentheses:

One study found that the most important element in comprehending non-native speech is familiarity with the topic (Gass & Varonis, 1984).

Author's name part of narrative:

Gass and Varonis (1984) found that the most important element in comprehending non-native speech is familiarity with the topic.

Group as author: First citation: (American Psychological Association [APA], 2015) Subsequent citation: (APA, 2015)

Multiple works: (separate each work with semi-colons)

Research shows that listening to a particular accent improves comprehension of accented speech in general (Gass & Varonis, 1984; Krech Thomas, 2004).

Direct quote: (include page number and place quotation marks around the direct quote)

One study found that “the listener's familiarity with the topic of discourse greatly facilitates the interpretation of the entire message” (Gass & Varonis, 1984, p. 85).

Gass and Varonis (1984) found that “the listener’s familiarity with the topic of discourse greatly facilitates the interpretation of the entire message” (p. 85).

Note:  For direct quotations of more than 40 words , display the quote as an indented block of text without quotation marks and include the authors’ names, year, and page number in parentheses at the end of the quote. For example:

This suggests that familiarity with nonnative speech in general, although it is clearly not as important a variable as topic familiarity, may indeed have some effect. That is, prior experience with nonnative speech, such as that gained by listening to the reading, facilitates comprehension. (Gass & Varonis, 1984, p. 77)

Works by Multiple Authors

APA style has specific rules for citing works by multiple authors. Use the following guidelines to determine how to correctly cite works by multiple authors in text. For more information on citing works by multiple authors see the APA Style and Grammar Guidelines page on in-text citation .

Note: When using multiple authors' names as part of your narrative, rather than in parentheses, always spell out the word and. For multiple authors' names within a parenthetic citation, use &.

One author: (Field, 2005)

Two authors: (Gass & Varonis, 1984)

Three or more authors:   (Tremblay et al., 2010)

Why Cite Resources?

Citing sources in the body of a research paper tells the reader that outside source material was used in the sentence where the in-text citation appears.  This lets the reader know it is not their original work or thought. Citing sources:

  • Lets the reader know whose research or ideas or theories influenced the paper's author
  • Provides authority and support for the positions taken in the paper
  • Acknowledges others in the field by giving credit for their original work

In-text citations also serve as finding tools. Because in-text citations are composed of the first two elements of the reference for the resource (author's last name and publication date), it provides the reader with enough information to find the resource in the paper’s References list. In other words, in-text citations and references match!

             

What Needs to be Cited?

According to the Publication Manual of the American Psychological Association (7th ed.),

" Plagiarism is the act of presenting the words, ideas, or images of another as one's own; it denies authors credit where credit is due" (American Psychological Association, 2020, p. 21).

In other words, using information from source material must be cited in the text and in the Reference list of APA-style papers.  This includes using others:

  • Words  - Quotations
  • Ideas  - Summaries, Paraphrases
  • Data  - Numbers, Data
  • Images   - Pictures, Charts, Graphs

View examples of references and companion in-text citations in the References page s in the APA Guide.

Creating In-Text Citations: Paraphrases and Summaries

(Author, Date)       

APA style uses the Author-Date citation system. In-text citations appear in the text of the paper to let readers know that information in the sentence where the in-text citation appears was taken from source material. They are composed of the first two elements of the corresponding reference (Author, Date)  for the resource and are designed to be short to avoid disrupting the flow of the paper.

There are two types of in-text citation:

  • Parenthetical

Parenthetical In-Text Citation

This is the most common form of in-text citation.  It is composed of the author(s) last name and the year of publication. It is called a parenthetical citation because this information is enclosed in parentheses. The parenthetical citation appears at the end of the sentence where information from the source was used and, because it is a part of the sentence, appears before the period. See the example of a parenthetical citation below:

Students reported they prefer writing on a computer rather than with paper and pen  (Cheung, 2016) .

Narrative In-Text Citation

The narrative citation is used when the author's name is used in a sentence. In this case, the year of publication enclosed in parentheses follows the author's name in the sentence. See the example of a narrative citation below:

In his survey, Cheung  (2016)  found that undergraduate writers produced higher quality writing when composing on a computer rather than with paper and pen.

In-Text Citations and References are Connected and Match!

In-text citations have two functions. First, they alert the reader that information from source material was used in a sentence where the in-text citation appears. It lets the reader know who's work influenced the writer's position or conclusions on the topic. Second, it serves as a finding tool so that the reader can quickly find the full reference in the reference list. The reference and in-text citation need to match. The example below illustrates how these match:

undefined

In-text citations follow the Author-Date pattern. In-text citations can appear at the end of a sentence (parenthetical in-text citation) or in the text of the sentence if the author's name is incorporated (narrative in-text citation). If a work is by three or more authors, list the first author's last name followed by the phrase "et al." and the year of publication.

Examples of in-text citations for works by one author, two authors, three or more authors, and group authors appear below:

Work by One Author

    Parenthetical in-text citation              (Davis, 2019).

    Narrative in-text citation                     According to Davis (2019),...

Work by Two Authors

    Parenthetical in-text citation              (Ryan & Cooper, 2020).

    Narrative in-text citation                     In the study conducted by Ryan and Cooper (2020),...

Work by Three or More Authors

   Parenthetical in-text citation              (Morrison et al., 2018).

    Narrative in-text citation                     In the Morrison et al. (2018) study,...

Work by Group Author

    Parenthetical in-text citation

  • First citation                                 (American Nurses Association [ANA], 2019).
  • Subsequent citation                     (ANA, 2019).

   Narrative in-text citation

  • First citation                                  The Centers for Disease Control and Prevention (CDC, 2020) report...
  • Subsequent citation                     According to the CDC (2020), recommendations include...                      

       

Placing In-Text Citations

In-text citations follow the Author-Date pattern and appear in the sentence where information from source material is used.  Placement of in-text citations vary depending on whether the author(s) name is incorporated into the sentence (narrative citation) or if the author(s) is not named directly in the sentence (parenthetical citation). In-text citations are a part of the sentence and appear before the ending period.

Parenthetical Citations

A parenthetical citation appears when information from source material is used, but the author(s) name is not included in the sentence text. This type of in-text citation is composed of the author(s) last name comma year of publication enclosed in parentheses. It is placed at the end of the sentence before the ending period.  

Narrative Citations

A narrative citation is used when the author(s) name is included in the sentence text. In this case, the year of publication is enclosed in parentheses and appears after the author(s) name.

In his survey,  Cheung  (2016)   found that undergraduate writers produced higher quality writing when composing on a computer rather than with paper and pen.

Creating In-Text Citations: Quotations

Author-Date-#   pattern:

When you copy a portion of the text directly from a source, it is called a  direct quotation . You will enclose the quote in quotation marks, and your citation will contain the last name of the author(s), the year of publication, and page number of where the quote can be found in the source:

If you are using a source that has  pages , then you will use an abbreviated p.:

(Smith, 2018, p. 4).

If you are using a source that does not have pages (a website), then you will use a  paragraph number . You will count down to the paragraph where your quote is located. You will use an abbreviated para.: 

(Wilson & Miller, 2019, para. 2).

Parenthetical In-Text Citation:

If the author’s name is not incorporated in your sentence include the author’s last name, year of publication, and page or paragraph number separated with commas and enclosed in parentheses at the end of the quotation: 

Many writers appreciate the “ability to edit instantaneously”  (Smith, 2008, p. 72)  when writing in pencil or on a computer.

If you incorporate the author’s name into your sentence follow the author's name with the year of publication in parentheses and include the location in parentheses directly following the quote:

In his survey,  Miller (2006)  found that some writers like the sound “of graphite turning ideas into reality”  (p. 72)  when writing in pencil. 

Quotations of 40 or More Words Require Block Format

Quotations of 40 or more words included in a paper are presented in block format. The quotation begins on a new line and the whole quotation is indented 1/2 inch from the left margin. No quotation marks are used and the citation appears at the end of the quotation after the final punctuation mark. In fact, this is the only situation where a parenthetical reference appears outside of a period!

Writing Tip:    Block quotations should be used sparingly.   Remember that your voice is important -- after all it is your paper! Instead of using a block quotation, consider taking pieces of the larger quote and either paraphrase them (put their ideas into your own words and provide an in-text citation) or include precise, shorter quotations from the larger quote, integrated into your own sentences. Either approach will help to ensure that you (the writer) have engaged with information in the quote and directly applied it to the topic of the paper.

Here is an example of a block quotation. Note: Normally the passage would be double spaced but, due to space restrictions, this example is single spaced.

Place direct quotations longer than 40 words 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 reference should come after the closing punctuation mark. (Angeli, et al., 2018, para. 27)

To create a block quotation, use the block indent button:

how to put in text citations in a research paper

Although paraphrasing information is preferable, there are specific situations when a quotation can be an effective choice.  For example:

  • Including a famous or familiar quotation can be effective when introducing a topic or in setting the tone of a paper.
  • Providing the words of an expert can bolster your position or argument.
  • In rare instances, it may be difficult to paraphrase a short passage without changing the meaning; including a precise quotation may be preferable.
  • Sources of facts and statistics--including those presented in tables or charts -- must be documented in your paper using in-text citations and references.
  • Including a quotation that opposes your position can be an effective method to prove why your position on the issue is preferable.

Paraphrases and Summaries

Author-Date  pattern:

When you  summarize ,  paraphrase , or otherwise refer to an idea, concept, or fact gained through your research, your citation will contain the last name of the author(s) and the year of publication:

(Smith, 2018)

(Wilson & Miller, 2019)

Qualities of a "Good" Paraphrase

Academic writing often requires students to integrate information found in source material.  There are various ways to do this; quotations, summaries, or paraphrases.  A  paraphrase  is a detailed restatement in your own words of main ideas from the portion of the source that is paraphrased.

Creating a well-written paraphrase can be a challenging skill to learn.  Understanding the qualities of a "good" paraphrase can help. A well-written paraphrase includes the following qualities:

  • All of the main details in the original appear in the paraphrase
  • The paraphrase does not change the original author's meaning.
  • ​The paraphrase is roughly the same length or shorter than the original. 
  • ​ The paraphrase is written using language, tone, and style that is your own.
  • ​ Paraphrased material must include both an in-text citation and a reference in the References list.

Example of a well-written paraphrase:

Original Passage:

University of Tulsa psychologist Judy Berry studied seventy-three Oklahoma eighth graders who had taken a parenting course.  For ten days, each student had to care for a ten-pound sack of flour as if it were a baby.  Berry's research on her young subjects suggests the course worked.  The teenagers in the study had a sounder sense of parental responsibility than they did before they took the course.

Harper, K. S. (1996). 'Flour babies' surrogacy teaches eight-graders parenting skills.  Journal of Child and Family Studies, 25 (4), 25-28.

Example of a Good Paraphrase:

Extended parental role-playing can actually increase an adolescent's awareness of parental responsibilities as shown by psychologist Judy Berry's study involving eighth grade students (Harper, 1996).

Avoid Patch Writing!

Students learning how to paraphrase may inadvertently "patch write."  Patch writing occurs when a writer uses a passage from source material and changes a few words and phrases before including the passage in a paper or assignment.  Not only is this  "bad" paraphrasing but it is also a form of plagiarism.  View the example below to gain a better understanding of patch writing:

University of Tulsa psychologist Judy Berry studied seventy-three Oklahoma eighth graders who had taken a parenting course.  For ten days, each student had to care for a ten-pound sack of flour as if it were a baby.  Berry's research on her young subjects suggests the course worked.  The teenagers in the study had a sounder sense of parental responsibility than they did before they took the course.

Patchwriting Example:

University of Tulsa psychologist Judy Berry  studied  eighth graders who had taken a parenting course.  Students had to treat  a ten-pound sack of flour as if it were a baby.   The results of Berry's study suggested  that teenagers in the study had a  better understanding  of parental responsibility than they did before they took the course  (Harper, 1996).

TIP:   Notice how the bolded phrases are identical to the original.  Even though there is an in-text citation, patchwriting is still a form of plagiarism.

A parenthetical citation includes the last name(s) of the author(s) followed by a comma and the page number(s). The parenthetical citation can be at the end of a sentence or may be in the middle of a sentence if needed to be clear on what is being cited.

A company should always do what is right regardless of the consequences, but doing the right thing tends to result in the best outcomes (Dunn, 2016).

Because doing the right thing is always the best choice (Dunn, 2016), corporate leaders must carefully develop a strong ethical compass.

A narrative citation is used when the author’s name is part of the text. In these cases, the author’s name does not need to be repeated in the parenthetical reference.

Dunn (2016) asserts the view that though a company should do what is right regardless of the potential consequences, ethical actions often produce the best possible outcomes for all (p. 22).

When quoting a source directly, page numbers are used to indicate the location of the quoted text. Though page numbers are not required for a paraphrase, it may be helpful to include page numbers to indicate the location of the paraphrased text. If the source has no page numbers, other location indicators, such as paragraph or section numbers may be used.

“Fundraising is an art and a science” (Garry, 2017, p. 99).

It is hard to predict how donors will respond to an appeal, but in time fundraisers learn to trust their intuition regarding the best approach (Garry, 2017, p. 99).

Personal communications are sources that can not be recovered or accessed by the reader because they are not published. This includes emails, texts, conversations (in person, by phone or video conference, etc.), online chats, interviews, classroom lectures, memos, letters, etc. If the information is not available from any recoverable (published) source, it can be cited as a personal communication. Because the reader can not access the information in personal communications, they will not be included in the reference list, but cited in the text only.

Quick guide to Harvard referencing (Cite Them Right)

  • Site Accessibility: Library Services

how to put in text citations in a research paper

Print this page

There are different versions of the Harvard referencing style. This guide is a quick introduction to the commonly-used Cite Them Right version. You will find further guidance available through the OU Library on the Cite Them Right Database .

For help and support with referencing and the full Cite Them Right guide, have a look at the Library’s page on referencing and plagiarism . If you need guidance referencing OU module material you can check out which sections of Cite Them Right are recommended when referencing physical and online module material .

This guide does not apply to OU Law undergraduate students . If you are studying a module beginning with W1xx, W2xx or W3xx, you should refer to the Quick guide to Cite Them Right referencing for Law modules .

Table of contents

In-text citations and full references.

  • Secondary referencing
  • Page numbers
  • Citing multiple sources published in the same year by the same author

Full reference examples

Referencing consists of two elements:

  • in-text citations, which are inserted in the body of your text and are included in the word count. An in-text citation gives the author(s) and publication date of a source you are referring to. If the publication date is not given, the phrase 'no date' is used instead of a date. If using direct quotations or you refer to a specific section in the source you also need the page number/s if available, or paragraph number for web pages.
  • full references, which are given in alphabetical order in reference list at the end of your work and are not included in the word count. Full references give full bibliographical information for all the sources you have referred to in the body of your text.

To see a reference list and intext citations check out this example assignment on Cite Them Right .

Difference between reference list and bibliography

a reference list only includes sources you have referred to in the body of your text

a bibliography includes sources you have referred to in the body of your text AND sources that were part of your background reading that you did not use in your assignment

Back to top

Examples of in-text citations

You need to include an in-text citation wherever you quote or paraphrase from a source. An in-text citation consists of the last name of the author(s), the year of publication, and a page number if relevant. There are a number of ways of incorporating in-text citations into your work - some examples are provided below. Alternatively you can see examples of setting out in-text citations in Cite Them Right .

Note: When referencing a chapter of an edited book, your in-text citation should give the author(s) of the chapter.

Cite your sources

  • is the right thing to do  to give credit to those who had the idea
  • shows that you have read and understand  what experts have had to say about your topic
  • helps people find the sources  that you used in case they want to read more about the topic
  • provides   evidence  for your arguments
  • is professional and  standard practice   for students and scholars

What is a Citation?

A citation identifies for the reader the original source for an idea, information, or image that is referred to in a work.

  • In the body of a paper, the  in-text citation  acknowledges the source of information used.
  • At the end of a paper, the citations are compiled on a  References  or  Works Cited  list. A basic citation includes the author, title, and publication information of the source. 

Citation basics

From:  Lemieux  Library,  University  of Seattle 

Why Should You Cite?

Quoting Are you quoting two or more consecutive words from a source? Then the original source should be cited and the words or phrase placed in quotes. 

Paraphrasing If an idea or information comes from another source,  even if you put it in your own words , you still need to credit the source.  General vs. Unfamiliar Knowledge You do not need to cite material which is accepted common knowledge. If in doubt whether your information is common knowledge or not, cite it. Formats We usually think of books and articles. However, if you use material from web sites, films, music, graphs, tables, etc. you'll also need to cite these as well.

Plagiarism is presenting the words or ideas of someone else as your own without proper acknowledgment of the source. When you work on a research paper and use supporting material from works by others, it's okay to quote people and use their ideas, but you do need to correctly credit them. Even when you summarize or paraphrase information found in books, articles, or Web pages, you must acknowledge the original author.

OWL logo

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.

A Quick Guide to Harvard Referencing | Citation Examples

Published on 14 February 2020 by Jack Caulfield . Revised on 15 September 2023.

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list .

Harvard in-text citation, creating a harvard reference list, harvard referencing examples, referencing sources with no author or date, frequently asked questions about harvard referencing.

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘ et al. ’:

Sources with no page numbers

Some sources, such as websites , often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

Prevent plagiarism, run a free check.

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Harvard reference list example

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘ et al. ’:

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

  • Entire book
  • Book chapter
  • Translated book
  • Edition of a book

Journal articles

  • Print journal
  • Online-only journal with DOI
  • Online-only journal with no DOI
  • General web page
  • Online article or blog
  • Social media post

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

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.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

Though the terms are sometimes used interchangeably, there is a difference in meaning:

  • A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
  • A bibliography also includes other sources which were consulted during the research but not cited.

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 Quote

Table of contents

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.

how to put in text citations in a research paper

Try for free

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.

how to put in text citations in a research paper

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.

Why are citations important?

Apa citations.

Good research projects combine data from a variety of sources and carefully document the sources of information and ideas. Research documentation usually appears in two parts: short in-text citations occurring within the actual paper and a longer, complete list of works at the end of the paper called a bibliography, reference list, or works cited page. 

Besides giving credit to the source of information or ideas, there are other great reasons to cite in your research project:

  • Persuasiveness - Your writing will be more persuasive if you cite the research on which you based your own conclusions and arguments.
  • Sharing - Citations make it possible for your professor and other readers to examine interesting sources that you found.
  • Communication -  Correct citations helps you communicate effectively with potential peers within a discipline.
  • Skills -  Correct citation demonstrates your research and documentation abilities to your professor.
  • Avoid Plagiarism -  Correct citation use helps protect you from plagiarizing.

Note: a hyperlink or URL included in the text is not the same as a citation. Ex: "Higher gas prices are on the way (cnn.com/specialreport)." URLs in the text, while common on the internet, are not considered a correct form of scholarly citation.
