How to Cite Page Numbers in APA

Last Updated: July 12, 2024 Fact Checked

Page numbers are a small but important part of many APA citations. Fortunately, page numbers are usually only needed at the end of a sentence when citing a specific source. When writing a reference list, you only need page numbers for book chapters and articles. If you’re uncertain whether you need page numbers or not, you can follow a few basic guidelines. When in doubt, however, include a page number if you have one.

Template and Examples

Using In-Text Citations

• For example, if you found a quote on page 10 of a book, cite page 10.
• If the information was spread over several pages, include all of them. So you might cite pages 10-16.
• Sometimes, page numbers might have letters like "B1" or use Roman numerals like "iv" or "xi." In these cases, always use the type of numbering used by the source.

• If you name the author in the sentence, write the year that the source was published in parentheses next to the author’s name. For example, you might write, “Smith (2010) showed that poor hygiene was correlated with low self-esteem.”

• If you named the author in the sentence, just put the page number at the end of the sentence. For example, “Smith (2010) showed that poor hygiene was correlated with low self-esteem (p. 40).”
• If you did not name the author within the text of the sentence, include the author’s last name and the year of publication before the page number in the parentheses. For example, “One study showed that poor hygiene was correlated with low self-esteem (Smith, 2010, p. 40).”

• A single page number citation might look like (Smith, 2010, p. 40) or (p. 40).
• A citation for multiple, sequential pages might look like (Smith, 2010, pp. 40-45) or (pp. 40-45).

Writing a Reference List

• Newspaper articles may have page numbers that include letters (such as 1A or B3) while prefaces may use roman numerals (like i, ii, iii, etc.). Always use the numbering system used by the source.
• If the article skips pages, write down where the pages begin and end in both sections. Put a comma between these page numbers. For example, 15-20, 25-30.
• Make sure to include reference lists, appendixes, and other supplementary material in your page range. So if the text of the article ends on page 173 but the appendix ends on page 180, then the page range ends on page 180.

• Book chapter: Last name, First Initial. Second Initial (if applicable). (Year of publication). Title of chapter. In A. Editor & B. Editor (Eds.), Title of book (pages of chapter). Location: Publisher.
• Article: Author, A. & Author, B. (Year). Title of article. Title of periodical, volume number (issue number), pages of article.

• Williams, B. and Johnson, A. (1990). Traffic Patterns and Urban Spread. in C. Carr (Ed.), Traffic Engineering Trends (pp. 41-63). New York: ZMN Publishing.

• Roberts, R. (2013). Managing Traffic in the Southwest. Traffic Engineering, 23 (2), 5-23.

• Diaz, C. (2016, June 26). “Traffic in the City,” The Times Morning Gazette , pp. B1, B3-B4.

Knowing When to Use Page Numbers

• For example, you might write, “According to Jones (2006), 5% of people were on social media 5 or more hours a day (p. 207).”

• Jones (2006) stated that “the top 5% of users were on social media for 5 or more hours every day” (p. 207).

• “Jones (2006) indicated that addictive behaviors could be seen in a small population of excessive users (p. 207).”

• You can cite a paragraph the same way as a page number, except you write “para.” instead of “p.” So if you were quoting paragraph 3, it would look like (para. 3) or even (James, 2007, para. 3).
• To find the paragraph number, count from the top paragraph down to the paragraph you are citing. So a quote from the third paragraph would be cited as paragraph 3.

About This Article

To cite page numbers in APA using in-text citations, start by identifying the page number or numbers of your source. Then, write the page number or numbers in parentheses at the end of the corresponding sentence in your paper. Put "p." before the page number if you're citing information from a single page, and use "pp." for multiple consecutive pages. Be sure to separate a range of page numbers with a hyphen! If you didn't name the author within the text of the sentence, you'll also need to include the author’s last name and the publication year before the page numbers in the parentheses. For example, “One study showed that poor hygiene was correlated with low self-esteem (Smith, 2010, p. 40).” A single page number citation might look like (Smith, 2010, p. 40) or (p. 40). A citation for multiple sequential pages might look like (Smith, 2010, pp. 40-45) or (pp. 40-45). To learn how to cite information from 2 or more non-consecutive pages, read on!

• In-Text Citation Checklist Checklist provided by APA to help make sure your in-text citations are correct.

There are two basic ways to cite someone's work in text.

In narrative citations , the authors are part of the sentence - you are referring to them by name. For example:

Becker (2013) defined gamification as giving the mechanics of principles of a game to other activities.

Cho and Castañeda (2019) noted that game-like activities are frequently used in language classes that adopt mobile and computer technologies.

In parenthetical citations , the authors are not mentioned in the sentence, just the content of their work. Place the citation at the end of the sentence or clause where you have used their information. The author's names are placed in the brackets (parentheses) with the rest of the citation details:

Gamification involves giving the mechanics or principles of a game to another activity (Becker, 2013).

Increasingly, game-like activities are frequently used in language classes that adopt mobile and computer technologies (Cho & Castañeda, 2019).

Using references in text

For APA, you use the authors' surnames only and the year in text. If you are using a direct quote, you will also need to use a page number.

Narrative citations:

If an in-text citation has the authors' names as part of the sentence (that is, outside of brackets) place the year and page numbers in brackets immediately after the name, and use 'and' between the authors' names:  Jones and Smith (2020, p. 29)

Parenthetical citations:

If an in-text citation has the authors' names in brackets use "&" between the authors' names :  (Jones & Smith, 2020, p. 29).

Note: Some lecturers want page numbers for all citations, while some only want page numbers with direct quotes. Check with your lecturer to see what you need to do for your assignment. If the direct quote starts on one page and finishes on another, include the page range (Jones & Smith, 2020, pp. 29-30).

1 author

Smith (2020) found that "the mice disappeared within minutes" (p. 29).

The author stated "the mice disappeared within minutes" (Smith, 2020, p. 29).

Jones and Smith (2020) found that "the mice disappeared within minutes" (p. 29).

The authors stated "the mice disappeared within minutes" (Jones & Smith, 2020, p. 29).

For 3 or more authors , use the first author and "et al." for all in-text citations

Green et al.'s (2019) findings indicated that the intervention was not based on evidence from clinical trials.

It appears the intervention was not based on evidence from clinical trials (Green et al., 2019).

If you cite more than one work in the same set of brackets in text , your citations will go in the same order in which they will appear in your reference list (i.e. alphabetical order, then oldest to newest for works by the same author) and be separated by a semi-colon. E.g.:

• (Corbin, 2015; James & Waterson, 2017; Smith et al., 2016).
• (Corbin, 2015; 2018)
• (Queensland Health, 2017a; 2017b)
• Use only the   surnames   of your authors   in text   (e.g., Smith & Brown, 2014) - however, if you have two authors with the same surname who have published in the same year, then you will need to use their initials to distinguish between the two of them (e.g., K. Smith, 2014; N. Smith, 2014).   Otherwise, do not use initials in text .

If your author isn't an "author".

Whoever is in the "author" position of the refence in the references list is treated like an author in text. So, for example, if you had an edited book and the editors of the book were in the "author" position at the beginning of the reference, you would treat them exactly the same way as you would an author - do not include any other information. The same applies for works where the "author" is an illustrator, producer, composer, etc.

• Summarising
• Paraphrasing

It is always a good idea to keep direct quotes to a minimum. Quoting doesn't showcase your writing ability - all it shows is that you can read (plus, lecturers hate reading assignments with a lot of quotes).

You should only use direct quotes if the exact wording is important , otherwise it is better to paraphrase.

If you feel a direct quote is appropriate, try to keep only the most important part of the quote and avoid letting it take up the entire sentence - always start or end the sentence with your own words to tie the quote back into your assignment. Long quotes (more than 40 words) are called "block quotes" and are rarely used in most subject areas (they mostly belong in Literature, History or similar subjects). Each referencing style has rules for setting out a block quote. Check with your style guide .

It has been observed that "pink fairy armadillos seem to be extremely susceptible to stress" (Superina, 2011, p. 6).

NB! Most referencing styles will require a page number to tell readers where to find the original quote.

It is a type of paraphrasing, and you will be using this frequently in your assignments, but note that summarising another person's work or argument isn't showing how you make connections or understand implications. This is preferred to quoting, but where possible try to go beyond simply summarising another person's information without "adding value".

And, remember, the words must be your own words . If you use the exact wording from the original at any time, those words must be treated as a direct quote.

All information must be cited, even if it is in your own words.

Superina (2011) observed a captive pink fairy armadillo, and noticed any variation in its environment could cause great stress.

NB! Some lecturers and citation styles want page numbers for everything you cite, others only want page numbers for direct quotes. Check with your lecturer.

Paraphrasing often involves commenting about the information at the same time, and this is where you can really show your understanding of the topic. You should try to do this within every paragraph in the body of your assignment.

When paraphrasing, it is important to remember that using a thesaurus to change every other word isn't really paraphrasing. It's patchwriting , and it's a kind of plagiarism (as you are not creating original work).

Use your own voice! You sound like you when you write - you have a distinctive style that is all your own, and when your "tone" suddenly changes for a section of your assignment, it looks highly suspicious. Your lecturer starts to wonder if you really wrote that part yourself. Make sure you have genuinely thought about how *you* would write this information, and that the paraphrasing really is in your own words.

Always cite your sources! Even if you have drawn from three different papers to write this one sentence, which is completely in your own words, you still have to cite your sources for that sentence (oh, and excellent work, by the way).

Captive pink fairy armadillos do not respond well to changes in their environment and can be easily stressed (Superina, 2011).

NB! Some lecturers and citation styles want page numbers for all citations, others only want them for direct quotes. Check with your lecturer.

Excerpt from "The Big Fake Essay"

You can read the entire Big Fake Essay on the Writing Guide. It includes more details about academic writing and the formatting of essays.

• The Big Fake Essay
• Academic Writing Workshop

When you have multiple authors with the same surname who published in the same year:

If your authors have different initials, then include the initials:

As A. Smith (2016) noted...

...which was confirmed by J.G. Smith's (2016) study.

(A. Smith, 2016; J. G. Smith, 2016).

If your authors have the same initials, then include the name:

As Adam Smith noted...

...which was confirmed by Amy Smith's (2016) study.

(Adam Smith, 2016; Amy Smith, 2016).

Note: In your reference list, you would include the author's first name in [square brackets] after their initials:

Smith, A. [Adam]. (2016)...

Smith, A. [Amy]. (2016)...

When you have multiple works by the same author in the same year:

In your reference list, you will have arranged the works alphabetically by title (see the page on Reference Lists for more information). This decides which reference is "a", "b", "c", and so on. You cite them in text accordingly:

Asthma is the most common disease affecting the Queensland population (Queensland Health, 2017b). However, many people do not know how to manage their asthma symptoms (Queensland Health, 2017a).

When you have multiple works by the same author in different years:

Asthma is the most common disease affecting the Queensland population (Queensland Health, 2017, 2018). 

When you do not have an author, and your reference list entry begins with the title:

Use the title in place of the author's name, and place it in "quotation marks" if it is the title of an article or book chapter, or in italics if the title would go in italics in your reference list:

During the 2017 presidential inauguration, there were some moments of awkwardness ("Mrs. Obama Says ‘Lovely Frame’", 2018).

Note: You do not need to use the entire title, but a reasonable portion so that it does not end too abruptly - "Mrs. Obama Says" would be too abrupt, but the full title "Mrs. Obama Says 'Lovely Frame' in Box During Awkward Handoff" is unecessarily long. You should also use title case for titles when referring to them in the text of your work.

If there are no page numbers, you can include any of the following in the in-text citation:

• "On Australia Day 1938 William Cooper ... joined forces with Jack Patten and William Ferguson ... to hold a Day of Mourning to draw attention to the losses suffered by Aboriginal people at the hands of the whiteman" (National Museum of Australia, n.d., para. 4).
• "in 1957 news of a report by the Western Australian government provided the catalyst for a reform movement" (National Museum of Australia, n.d., The catalyst for change section, para. 1)
• "By the end of this year of intense activity over 100,000 signatures had been collected" (National Museum of Australia, n.d., "petition gathering", para. 1).

When you are citing a classical work, like the Bible or the Quran:

References to works of scripture or other classical works are treated differently to regular citations. See the APA Blog's entry for more details:

Happy Holiday Citing: Citation of Classical Works . (Please note, this document is from the 6th edition of APA).

In text citation:

If the name of the organisation first appears in a narrative citation, include the abbreviation before the year in brackets, separated with a comma. Use the official acronym/abreviation if you can find it. Otherwise check with your lecturer for permission to create your own acronyms.

Australian Bureau of Statistics (ABS, 2013) shows that...

The Queensland Department of Education (DoE, 2020) encourages students to... (please note, Queensland isn't part of the department's name, it is used in the sentence to provide clarity)

If the name of the organisation first appears in a citation in brackets, include the abbreviation in square brackets.

(Australian Bureau of Statistics [ABS], 2013)

(Department of Education [DoE], 2020)

In the second and subsequent citations, only include the abbreviation or acronym

ABS  (2013) found that ...

DoE (2020) instructs teachers to...

This is disputed ( ABS , 2013).

Resources are designed to support "emotional learning pedagogy" (DoE, 2020)

In the reference list:

Use the full name of the organisation in the reference list.

Australian Institute of Health and Welfare. (2017).  Australia's welfare 2017 . https://www.aihw.gov.au/reports/australias-welfare/australias-welfare-2017/contents/table-of-contents

Department of Education. (2020, April 22). Respectful relationships education program . Queensland Government. https://education.qld.gov.au/curriculum/stages-of-schooling/respectful-relationships

Academically, it is better to find the original source and reference that.

If you do have to quote a secondary source:

• In the text you must cite the original author of the quote and the year the original quote was written as well as the source you read it in. If you do not know the year the original citation was written, omit the year.
• In the reference list you only list the source that you actually read.

Wembley (1997, as cited in Olsen, 1999) argues that impending fuel shortages ...

Wembley claimed that "fuel shortages are likely" (1997, as cited in Olsen, 1999, pp. 10-12).

Some have noted that fuel shortages are probable in the future (Wembley, 1997, as cited in Olsen, 1999).

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.

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)

How to Cite a Page Number in an Essay

Depending on the teacher and the level of research required to complete an essay, you may be required to cite your references within the article. To aid your citation later, write down the title of the book and the page number of any information you glean while taking notes. High school or college-level essays may draw on one of two different formatting styles. The Modern Language Association (MLA) formatting requires the writer to cite page numbers for all referenced material; however, the American Psychological Association (APA) only requires a page number within the citation when the material is a direct quote.

MLA Format for Page Number Citation

Locate the information you need to cite within the body of the essay. If all of the information in a paragraph came from the same page of the same source or contiguous pages of the same source, you only need to cite the last sentence in that paragraph. However, if you combined several sources or the information came from different or noncontiguous pages of the same source, you will need to provide a citation for each sentence or group of sentences.

Locate the last name of the author and page number(s) for the information.

Place the citation within parenthesis before the period of the last sentence of the information you wish to cite. If you are citing a direct quotation enclosed in quotation marks, place the citation outside the final quotation marks.

Format the citation as (last name, page number).

For example, information on page 36 from a book written by William Smith would be written as (Smith, 36).

APA Format of Direct Quote Citations

Locate the information you need to cite within the body of the essay.

Locate the author, date of publication and page number(s) for the information.

Enclose direct quotations within quotation marks.

Place the citation outside the final quotation mark. Enclose the citation within parenthesis and include the last name of the author, publication date of the source and page number according to the template (last name, date, p. page number).

For example, a quote taken from page 214 of a book written by Jane Phillips published in 2003 would be written as (Phillips, 2003, p. 214). APA style uses the "p." symbol before the page number, whereas MLA does not.

Place a period after the enclosed citation.

• For either MLA or APA format, if you state relevant citation information within the sentence you are referencing or before the quotation, you do not need to repeat the information within the citation.

APA In-Text Citations and Sample Essay 7th Edition

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

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

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

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

Citation Rules

Direct quotation with the author named in the text.

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

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

Direct Quotation without the Author Named in the Text

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

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

Paraphrase with 1-2 Authors

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

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

Paraphrase with 3 or More Authors

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

Direct Quotation without an Author

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

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

Secondary Sources

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

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

Long (Block) Quotations

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

At Meramec, an English department policy states:

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

Website Citations

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

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

MLA In-Text Citations: The Basics

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.

Guidelines for referring to the works of others in your text using MLA style are covered throughout the  MLA Handbook  and in chapter 7 of the  MLA Style Manual . Both books provide extensive examples, so it's a good idea to consult them if you want to become even more familiar with MLA guidelines or if you have a particular reference question.

Basic in-text citation rules

In MLA Style, referring to the works of others in your text is done using parenthetical citations . This method involves providing relevant source information in parentheses whenever a sentence uses a quotation or paraphrase. Usually, the simplest way to do this is to put all of the source information in parentheses at the end of the sentence (i.e., just before the period). However, as the examples below will illustrate, there are situations where it makes sense to put the parenthetical elsewhere in the sentence, or even to leave information out.

General Guidelines

• The source information required in a parenthetical citation depends (1) upon the source medium (e.g. print, web, DVD) and (2) upon the source’s entry on the Works Cited page.
• Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text must be the first thing that appears on the left-hand margin of the corresponding entry on the Works Cited page.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads . Oxford UP, 1967.

In-text citations for print sources with known author

For print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry on the Works Cited page:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method . University of California Press, 1966.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for sources with non-standard labeling systems

If a source uses a labeling or numbering system other than page numbers, such as a script or poetry, precede the citation with said label. When citing a poem, for instance, the parenthetical would begin with the word “line”, and then the line number or range. For example, the examination of William Blake’s poem “The Tyger” would be cited as such:

The speaker makes an ardent call for the exploration of the connection between the violence of nature and the divinity of creation. “In what distant deeps or skies. / Burnt the fire of thine eyes," they ask in reference to the tiger as they attempt to reconcile their intimidation with their relationship to creationism (lines 5-6).

Longer labels, such as chapters (ch.) and scenes (sc.), should be abbreviated.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name, following these guidelines.

Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number if it is available.

Titles longer than a standard noun phrase should be shortened into a noun phrase by excluding articles. For example, To the Lighthouse would be shortened to Lighthouse .

If the title cannot be easily shortened into a noun phrase, the title should be cut after the first clause, phrase, or punctuation:

In this example, since the reader does not know the author of the article, an abbreviated title appears in the parenthetical citation, and the full title of the article appears first at the left-hand margin of its respective entry on the Works Cited page. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs . 1999. www.climatehotmap.org/. Accessed 23 Mar. 2009.

If the title of the work begins with a quotation mark, such as a title that refers to another work, that quote or quoted title can be used as the shortened title. The single quotation marks must be included in the parenthetical, rather than the double quotation.

Parenthetical citations and Works Cited pages, used in conjunction, allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work, like Marx and Engels's  The Communist Manifesto . In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Author-page citation for works in an anthology, periodical, or collection

When you cite a work that appears inside a larger source (for instance, an article in a periodical or an essay in a collection), cite the author of the  internal source (i.e., the article or essay). For example, to cite Albert Einstein's article "A Brief Outline of the Theory of Relativity," which was published in  Nature  in 1921, you might write something like this:

See also our page on documenting periodicals in the Works Cited .

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Citing a work by multiple authors

For a source with two authors, list the authors’ last names in the text or in the parenthetical citation:

Corresponding Works Cited entry:

Best, David, and Sharon Marcus. “Surface Reading: An Introduction.” Representations , vol. 108, no. 1, Fall 2009, pp. 1-21. JSTOR, doi:10.1525/rep.2009.108.1.1

For a source with three or more authors, list only the first author’s last name, and replace the additional names with et al.

Franck, Caroline, et al. “Agricultural Subsidies and the American Obesity Epidemic.” American Journal of Preventative Medicine , vol. 45, no. 3, Sept. 2013, pp. 327-333.

Citing multiple works by the same author

If you cite more than one work by an author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author :

Citing two books by the same author :

Additionally, if the author's name is not mentioned in the sentence, format your citation with the author's name followed by a comma, followed by a shortened title of the work, and, when appropriate, the page number(s):

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter, and verse. For example:

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation:

John of Patmos echoes this passage when describing his vision (Rev. 4.6-8).

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited within another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing transcripts, plays, or screenplays

Sources that take the form of a dialogue involving two or more participants have special guidelines for their quotation and citation. Each line of dialogue should begin with the speaker's name written in all capitals and indented half an inch. A period follows the name (e.g., JAMES.) . After the period, write the dialogue. Each successive line after the first should receive an additional indentation. When another person begins speaking, start a new line with that person's name indented only half an inch. Repeat this pattern each time the speaker changes. You can include stage directions in the quote if they appear in the original source.

Conclude with a parenthetical that explains where to find the excerpt in the source. Usually, the author and title of the source can be given in a signal phrase before quoting the excerpt, so the concluding parenthetical will often just contain location information like page numbers or act/scene indicators.

Here is an example from O'Neill's  The Iceman Cometh.

WILLIE. (Pleadingly) Give me a drink, Rocky. Harry said it was all right. God, I need a drink.

ROCKY. Den grab it. It's right under your nose.

WILLIE. (Avidly) Thanks. (He takes the bottle with both twitching hands and tilts it to his lips and gulps down the whiskey in big swallows.) (1.1)

Citing non-print or sources from the Internet

With more and more scholarly work published on the Internet, you may have to cite sources you found in digital environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's  Evaluating Sources of Information  resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source on your Works Cited page.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers. However, these sorts of entries often do not require a page number in the parenthetical citation. For electronic and Internet sources, follow the following guidelines:

• Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
• Do not provide paragraph numbers or page numbers based on your Web browser’s print preview function.
• Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like  CNN.com  or  Forbes.com,  as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Two types of non-print sources you may encounter are films and lectures/presentations:

In the two examples above “Herzog” (a film’s director) and “Yates” (a presentor) lead the reader to the first item in each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo . Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002. Address.

Electronic sources

Electronic sources may include web pages and online news or magazine articles:

In the first example (an online magazine article), the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below).

In the second example (a web page), a parenthetical citation is not necessary because the page does not list an author, and the title of the article, “MLA Formatting and Style Guide,” is used as a signal phrase within the sentence. If the title of the article was not named in the sentence, an abbreviated version would appear in a parenthetical citation at the end of the sentence. Both corresponding Works Cited entries are as follows:

Taylor, Rumsey. "Fitzcarraldo." Slant , 13 Jun. 2003, www.slantmagazine.com/film/review/fitzcarraldo/. Accessed 29 Sep. 2009. 

"MLA Formatting and Style Guide." The Purdue OWL , 2 Aug. 2016, owl.english.purdue.edu/owl/resource/747/01/. Accessed 2 April 2018.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference. For example: (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations, or common knowledge (For example, it is expected that U.S. citizens know that George Washington was the first President.). Remember that citing sources is a rhetorical task, and, as such, can vary based on your audience. If you’re writing for an expert audience of a scholarly journal, for example, you may need to deal with expectations of what constitutes “common knowledge” that differ from common norms.

Other Sources

The MLA Handbook describes how to cite many different kinds of authors and content creators. However, you may occasionally encounter a source or author category that the handbook does not describe, making the best way to proceed can be unclear.

In these cases, it's typically acceptable to apply the general principles of MLA citation to the new kind of source in a way that's consistent and sensible. A good way to do this is to simply use the standard MLA directions for a type of source that resembles the source you want to cite.

You may also want to investigate whether a third-party organization has provided directions for how to cite this kind of source. For example, Norquest College provides guidelines for citing Indigenous Elders and Knowledge Keepers⁠ —an author category that does not appear in the MLA Handbook . In cases like this, however, it's a good idea to ask your instructor or supervisor whether using third-party citation guidelines might present problems.

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 a  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.

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 .

Example with one author:

Almeroth-Williams, T. (2019) City of Beasts: How Animals Shaped Georgian London . Manchester: Manchester University Press.

RSPCA (2024) Caring for cats and kittens . Available at: https://www.rspca.org.uk/adviceandwelfare/pets/cats (Accessed: 1 August 2024).

A Quick Guide to Page Numbers in Chicago Referencing

4-minute read

• 14th November 2020

Chicago referencing is widely used in academic writing . It has various rules for how and when to use page numbers. And it’s worth knowing these rules if you’re been asked to use Chicago style in your work. In this post, then, we’ll look at how to write page numbers in Chicago referencing.

Arabic vs. Roman Numerals

Generally, Chicago referencing requires you to use Arabic numerals (e.g., 1, 2, 3) instead of Roman numerals (e.g., i, ii, iii) for page numbers.

Roman numerals should only be used in Chicago referencing for the front matter of books, and only then if the source itself uses Roman numerals.

When to Use “P.” and “Pp.”

You should give page numbers in Chicago author–date and footnote references when you quote a print source directly. Page numbers are also required in a Chicago bibliography for a source within a container, such as a journal article or a chapter from an edited book.

In most cases, you can give page numbers by themselves. For instance:

1. W.B. Yeats , Collected Poems (New York: Scribner, 1996) , 123.

Here, we’re citing page 123 from a book. We know it is a page number because it comes at the end of a citation for a book and it is the only locator (i.e., something to pinpoint the part of the source cited) included.

However, the Chicago Manual of Style suggests using abbreviations for page (p.) and pages (pp.) when needed for clarity. Thus, if you give another number in a citation or footnote, such as a line number, you should add “p.” or “pp.” before the page number(s). For example:

2. W.B. Yeats , Collected Poems (New York: Scribner, 1996) , p. 123, lines 12–14.

Here, labelling the page number with “p.” and the line numbers with “lines” helps to prevent confusion. But you only need to use “p.” and “pp.” when giving page numbers alone could be ambiguous.

Page Ranges in Chicago Referencing

If you are referring to more than one page in a source, Chicago referencing has rules on how to present them. The rules for formatting an inclusive range of pages are outlined in the table below:

The exception to these rules is if you are using an inclusive range of Roman numerals, when you should always give them in full (e.g., “cxi–cxviii”).

For non-consecutive pages, meanwhile, separate numbers with commas:

We see this in more than one poem (Yeats, 1996, 24, 27).

Here, we’re citing pages 24 and 27, but not the intervening ones.

Sources Without Page Numbers

Some electronic sources, such as websites, don’t have page numbers. And for others, such as ebooks, the page numbering may depend on the format. Consequently, Chicago referencing doesn’t necessarily require you to give a pinpoint citation for sources without page numbers.

However, for longer or more complex documents where it could be hard to find an exact quote without a pinpoint citation, it is worth using an alternative locator if you can, such as a paragraph or chapter number.

Here are examples of how this could look in footnote references:

3. “William Butler Yeats,” Poetry Foundation, para. 4, accessed October 13, 2020, https://www.poetryfoundation.org/poets/william-butler-yeats. 4. W.B. Yeats, Fairy Tales of Ireland (New York: Harper Collins, 2019) , chap. 7, Kindle.

These locators will help readers to find the part of the source you’ve cited.

In-text citations: General notes

The MLA system uses in-text citations rather than footnotes or endnotes. The citations in-text are very brief, usually just the author's last name and a relevant page number, in parenthesis at a natural pause in your text.

The in-text citation should unambiguously direct the reader to the entry in your works-cited list at the end of your document.

Use of the author's name in an in-text citation

There is no need to repeat the author's name if it is already used in your sentence. This is called an 'author prominent' citation, and it will look something like this:

• "It was the best of times, it was the worst of times," wrote Charles Dickens of the eighteenth century (5) .

If you wish to emphasise the information you have paraphrased or quoted from an author, then your citation becomes 'information prominent', and you should include both the author's last name, and the relevant page number in parentheses.  The citation will look something like this:

• ... as demonstrated in the opening line, "it was the best of times, it was the worst of times"  (Dickens 5) .

Examples for in-text citations

Single author, less than three lines long.

More than three lines long (a "block quotation")

Poetry, more than three lines long (a "block quotation")

Indirect quotation from a source within a source

Two authors (coauthored)

Three or more authors

Corporate author

Descriptive phrase instead of title (e.g. introduction, preface)

Authors with the same last name

More than one work by the same author

Anonymous or no author

Paragraph numbers instead of page numbers

U.S. birth certificate data for 2023 show continued declines in the number (2%) and rate (3%) of births from 2022 to 2023. Since the most recent high in 2007, the number of births has declined 17%, and the general fertility rate has declined 21% ( 1 ). The teen birth rate also continued to decline in 2023 and has declined two-thirds since 2007 ( 1 ). The percentage of women beginning care in the first trimester of pregnancy declined in 2023 and was down 3% from the most recent high in 2021; first trimester care had been on the rise from 2016 to 2021. At the same time, the percentage of women with late care or with no care rose from 2021 to 2023; late and no-care levels have risen steadily since 2016 ( 1 ). The preterm birth rate was essentially unchanged from 2022 to 2023, but early-term births rose 2%, and full-term and late- and post-term births declined 1% and 3%, respectively. Since the most recent low in 2014, preterm birth rates have risen 9% and early-term births by 21%, while full-term and late- and post-term births have declined ( 1 ).

General fertility rate : Number of births per 1,000 females ages 15–44.

Gestational age : Preterm is births delivered before 37 completed weeks of gestation, early term is 37–38 weeks, full term is 39–40 weeks, and late and post term is 41 or later weeks. Gestational age is based on the obstetric estimate of gestation in completed weeks.

Teenage birth rates : Births per 1,000 females in the specified age groups 15–19, 15–17, and 18–19.

Trimester prenatal care began : The timing of care based on the date a physician or other health care provider examined or counseled the pregnant woman for the pregnancy and the obstetric estimate of gestational age.

This report uses data from the natality data file from the National Vital Statistics System. The vital statistics natality file is based on information from birth certificates and includes information for all births occurring in the United States. This Data Brief accompanies the release of the 2023 natality public-use file ( 2 ). More detailed analyses of the topics presented in this report and other topics such as births by age of mother, tobacco use during pregnancy, pregnancy risk factors, prenatal care timing and utilization, receipt of WIC food, maternal body mass index, and breastfeeding are possible by using the annual natality files ( 2 ). Additional information from the 2023 final birth data file is available via the CDC WONDER platform and will be included in the final 2023 National Vital Statistics Births Report.

References to increases or decreases in rates or percentages indicate differences are statistically significant at the 0.05 level based on a two-tailed z test. References to decreases in the number of births indicate differences are statistically significant at the 0.05 level based on a two-tailed chi-squared test. Computations exclude records for which information is unknown.

Rates shown in this report are based on population estimates calculated from a base that incorporates the 2020 census, vintage 2020 estimates for April 1, 2020, and 2020 demographic analysis estimates. Rates are calculated based on population estimates as of July 1, 2022, (vintage 2022) and July 1, 2023 (vintage 2023) ( 1 , 3 ). The vintage 2023 population estimates include methodological changes made after the release of the vintage 2022 population estimates and projection ( 4 , 5 ). Changes in rates from 2022 to 2023 reflect changes in births and changes in population estimates.

Paraphrases

A paraphrase restates another’s idea (or your own previously published idea) in your own words. Paraphrasing allows you to summarize and synthesize information from one or more sources, focus on significant information, and compare and contrast relevant details.

Published authors paraphrase their sources most of the time, rather than directly quoting the sources; student authors should emulate this practice by paraphrasing more than directly quoting.

When you paraphrase, cite the original work using either the narrative or parenthetical citation format .

Although it is not required to provide a page or paragraph number in the citation, you may include one (in addition to the author and year) when it would help interested readers locate the relevant passage within a long or complex work (e.g., a book).

Webster-Stratton (2016) described a case example of a 4-year-old girl who showed an insecure attachment to her mother; in working with the family dyad, the therapist focused on increasing the mother’s empathy for her child (pp. 152–153).

These guidelines pertain to when you read a primary source and paraphrase it yourself. If you read a paraphrase of a primary source in a published work and want to cite that source, it is best to read and cite the primary source directly if possible; if not, use a secondary source citation .

Paraphrases are covered in the seventh edition APA Style manuals in the Publication Manual Sections 8.23 and 8.24 and the Concise Guide Sections 8.23 and 8.24

Long paraphrases

A paraphrase may continue for several sentences. In such cases, cite the work being paraphrased on first mention. Once the work has been cited, it is not necessary to repeat the citation as long as the context of the writing makes it clear that the same work continues to be paraphrased.

Velez et al. (2018) found that for women of color, sexism and racism in the workplace were associated with poor work and mental health outcomes, including job-related burnout, turnover intentions, and psychological distress. However, self-esteem, person–organization fit, and perceived organizational support mediated these effects. Additionally, stronger womanist attitudes—which acknowledge the unique challenges faced by women of color in a sexist and racist society—weakened the association of workplace discrimination with psychological distress. These findings underscore the importance of considering multiple forms of workplace discrimination in clinical practice and research with women of color, along with efforts to challenge and reduce such discrimination.

If the paraphrase continues into a new paragraph, reintroduce the citation. If the paraphrase incorporates multiple sources or switches among sources, repeat the citation so the source is clear. Read your sentences carefully to ensure you have cited sources appropriately.

Play therapists can experience many symptoms of impaired wellness, including emotional exhaustion or reduced ability to empathize with others (Elwood et al., 2011; Figley, 2002), disruption in personal relationships (Elwood et al., 2011; Robinson-Keilig, 2014), decreased satisfaction with work (Elwood et al., 2011), avoidance of particular situations (Figley, 2002; O’Halloran & Linton, 2000), and feelings or thoughts of helplessness (Elwood et al., 2011; Figley, 2002; O’Halloran & Linton, 2000).

How to Cite a Website | MLA, APA & Chicago Examples

Published on March 5, 2021 by Jack Caulfield . Revised on January 17, 2024.

To cite a page from a website, you need a short in-text citation and a corresponding reference stating the author’s name, the date of publication, the title of the page, the website name, and the URL.

This information is presented differently in different citation styles. APA , MLA , and Chicago are the most commonly used styles.

Use the interactive example generator below to explore APA and MLA website citations.

Citing a website in mla style, citing a website in apa style, citing a website in chicago style, frequently asked questions about citations.

An MLA Works Cited entry for a webpage lists the author’s name , the title of the page (in quotation marks), the name of the site (in italics), the date of publication, and the URL.

The in-text citation usually just lists the author’s name. For a long page, you may specify a (shortened) section heading to locate the specific passage. Don’t use paragraph numbers unless they’re specifically numbered on the page.

The same format is used for blog posts and online articles from newspapers and magazines.

You can also use our free MLA Citation Generator to generate your website citations.

Citing a whole website.

When you cite an entire website rather than a specific page, include the author if one can be identified for the whole site (e.g. for a single-authored blog). Otherwise, just start with the site name.

List the copyright date displayed on the site; if there isn’t one, provide an access date after the URL.

Webpages with no author or date

When no author is listed, cite the organization as author only if it differs from the website name.

If the organization name is also the website name, start the Works Cited entry with the title instead, and use a shortened version of the title in the in-text citation.

When no publication date is listed, leave it out and include an access date at the end instead.

An APA reference for a webpage lists the author’s last name and initials, the full date of publication, the title of the page (in italics), the website name (in plain text), and the URL.

The in-text citation lists the author’s last name and the year. If it’s a long page, you may include a locator to identify the quote or paraphrase (e.g. a paragraph number and/or section title).

Note that a general reference to an entire website doesn’t require a citation in APA Style; just include the URL in parentheses after you mention the site.

You can also use our free APA Citation Generator to create your webpage citations. Search for a URL to retrieve the details.

Generate accurate APA citations with Scribbr

Blog posts and online articles.

Blog posts follow a slightly different format: the title of the post is not italicized, and the name of the blog is.

The same format is used for online newspaper and magazine articles—but not for articles from news sites like Reuters and BBC News (see the previous example).

When a page has no author specified, list the name of the organization that created it instead (and omit it later if it’s the same as the website name).

When it doesn’t list a date of publication, use “n.d.” in place of the date. You can also include an access date if the page seems likely to change over time.

In Chicago notes and bibliography style, footnotes are used to cite sources. They refer to a bibliography at the end that lists all your sources in full.

A Chicago bibliography entry for a website lists the author’s name, the page title (in quotation marks), the website name, the publication date, and the URL.

Chicago also has an alternative author-date citation style . Examples of website citations in this style can be found here .

For blog posts and online articles from newspapers, the name of the publication is italicized. For a blog post, you should also add the word “blog” in parentheses, unless it’s already part of the blog’s name.

When a web source doesn’t list an author , you can usually begin your bibliography entry and short note with the name of the organization responsible. Don’t repeat it later if it’s also the name of the website. A full note should begin with the title instead.

When no publication or revision date is shown, include an access date instead in your bibliography entry.

The main elements included in website citations across APA , MLA , and Chicago style are the author, the date of publication, the page title, the website name, and the URL. The information is presented differently in each style.

In APA , MLA , and Chicago style citations for sources that don’t list a specific author (e.g. many websites ), you can usually list the organization responsible for the source as the author.

If the organization is the same as the website or publisher, you shouldn’t repeat it twice in your reference:

• In APA and Chicago, omit the website or publisher name later in the reference.
• In MLA, omit the author element at the start of the reference, and cite the source title instead.

If there’s no appropriate organization to list as author, you will usually have to begin the citation and reference entry with the title of the source instead.

When you want to cite a specific passage in a source without page numbers (e.g. an e-book or website ), all the main citation styles recommend using an alternate locator in your in-text citation . You might use a heading or chapter number, e.g. (Smith, 2016, ch. 1)

In APA Style , you can count the paragraph numbers in a text to identify a location by paragraph number. MLA and Chicago recommend that you only use paragraph numbers if they’re explicitly marked in the text.

For audiovisual sources (e.g. videos ), all styles recommend using a timestamp to show a specific point in the video when relevant.

Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.

• APA Style is the most popular citation style, widely used in the social and behavioral sciences.
• MLA style is the second most popular, used mainly in the humanities.
• Chicago notes and bibliography style is also popular in the humanities, especially history.
• Chicago author-date style tends to be used in the sciences.

Other more specialized styles exist for certain fields, such as Bluebook and OSCOLA for law.

The most important thing is to choose one style and use it consistently throughout your text.

Abstract: One of the grand challenges of artificial general intelligence is developing agents capable of conducting scientific research and discovering new knowledge. While frontier models have already been used as aides to human scientists, e.g. for brainstorming ideas, writing code, or prediction tasks, they still conduct only a small part of the scientific process. This paper presents the first comprehensive framework for fully automatic scientific discovery, enabling frontier large language models to perform research independently and communicate their findings. We introduce The AI Scientist, which generates novel research ideas, writes code, executes experiments, visualizes results, describes its findings by writing a full scientific paper, and then runs a simulated review process for evaluation. In principle, this process can be repeated to iteratively develop ideas in an open-ended fashion, acting like the human scientific community. We demonstrate its versatility by applying it to three distinct subfields of machine learning: diffusion modeling, transformer-based language modeling, and learning dynamics. Each idea is implemented and developed into a full paper at a cost of less than $15 per paper. To evaluate the generated papers, we design and validate an automated reviewer, which we show achieves near-human performance in evaluating paper scores. The AI Scientist can produce papers that exceed the acceptance threshold at a top machine learning conference as judged by our automated reviewer. This approach signifies the beginning of a new era in scientific discovery in machine learning: bringing the transformative benefits of AI agents to the entire research process of AI itself, and taking us closer to a world where endless affordable creativity and innovation can be unleashed on the world's most challenging problems.
