Table of Contents

Journal article from library database with doi - one author, journal article from library database with doi - multiple authors, journal article from a website - one author.

Journal Article- No DOI

Note: All citations should be double spaced and have a hanging indent in a Reference List.

A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

This Microsoft support page contains instructions about how to format a hanging indent in a paper.

• APA 7th. ed. Journal Article Reference Checklist

If an item has no author, start the citation with the article title.

When an article has one to twenty authors, all authors' names are cited in the References List entry. When an article has twenty-one or more authors list the first nineteen authors followed by three spaced ellipse points (. . .) , and then the last author's name. Rules are different for in-text citations; please see the examples provided.

Cite author names in the order in which they appear on the source, not in alphabetical order (the first author is usually the person who contributed the most work to the publication).

Italicize titles of journals, magazines and newspapers. Do not italicize or use quotation marks for the titles of articles.

Capitalize only the first letter of the first word of the article title. If there is a colon in the article title, also capitalize the first letter of the first word after the colon.

If an item has no date, use the short form n.d. where you would normally put the date.

Volume and Issue Numbers

Italicize volume numbers but not issue numbers.

Retrieval Dates

Most articles will not need these in the citation. Only use them for online articles from places where content may change often, like a free website or a wiki.

Page Numbers

If an article doesn't appear on continuous pages, list all the page numbers the article is on, separated by commas. For example (4, 6, 12-14)

Library Database

Do not include the name of a database for works obtained from most academic research databases (e.g. APA PsycInfo, CINAHL) because works in these resources are widely available. Exceptions are Cochrane Database of Systematic Reviews, ERIC, ProQuest Dissertations, and UpToDate.

Include the DOI (formatted as a URL: https://doi.org/...) if it is available. If you do not have a DOI, include a URL if the full text of the article is available online (not as part of a library database). If the full text is from a library database, do not include a DOI, URL, or database name.

In the Body of a Paper

Books, Journals, Reports, Webpages, etc.: When you refer to titles of a “stand-alone work,” as the APA calls them on their APA Style website, such as books, journals, reports, and webpages, you should italicize them. Capitalize words as you would for an article title in a reference, e.g., In the book Crying in H Mart: A memoir , author Michelle Zauner (2021) describes her biracial origin and its impact on her identity.

Article or Chapter: When you refer to the title of a part of a work, such as an article or a chapter, put quotation marks around the title and capitalize it as you would for a journal title in a reference, e.g., In the chapter “Where’s the Wine,” Zauner (2021) describes how she decided to become a musician.

The APA Sample Paper below has more information about formatting your paper.

• APA 7th ed. Sample Paper

Author's Last Name, First Initial. Second Initial if Given. (Year of Publication). Title of article: Subtitle if any. Name of Journal, Volume Number (Issue Number), first page number-last page number. https://doi.org/doi number

Smith, K. F. (2022). The public and private dialogue about the American family on television: A second look. Journal of Media Communication, 50 (4), 79-110. https://doi.org/10.1152/j.1460-2466.2000.tb02864.x

Note: The DOI number is formatted as a URL: https://doi.org/10.1152/j.1460-2466.2000.tb02864.xIf. 

In-Text Paraphrase:

(Author's Last Name, Year)

Example: (Smith, 2000)

In-Text Quote:

(Author's Last Name, Year, p. Page Number)

Example: (Smith, 2000, p. 80)

Author's Last Name, First Initial. Second Initial if Given., & Last Name of Second Author, First Initial. Second Initial if Given. (Year of Publication). Title of article: Subtitle if any. Name of Journal, Volume Number (Issue Number), first page number-last page number. https://doi.org/doi number

Note: Separate the authors' names by putting a comma between them. For the final author listed add an ampersand (&) after the comma and before the final author's last name.

Note: In the reference list invert all authors' names; give last names and initials for only up to and including 20 authors. When a source has 21 or more authors, include the first 19 authors’ names, then three ellipses (…), and add the last author’s name. Don't include an ampersand (&) between the ellipsis and final author.

Note : For works with three or more authors, the first in-text citation is shortened to include the first author's surname followed by "et al."

• Unknown Author
• If a journal article has a DOI, include the DOI in the reference.
• If the journal article does not have a DOI and is from an academic research database, end the reference after the page range (for an explanation of why, see the  database information  page). The reference in this case is the same as for a print journal article.
• Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate (see an example on the official APA Style  database information  page).
• If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a database), include the URL of the article at the end of the reference.

Tips for Multiple Authors

Provide surnames and initials for up to and including 20 authors. When there are two to 20 authors, use an ampersand before the final author's name.

• Example: Author, A. A., Author, B. B., & Author, C. C.

When there are 21 or more authors, include the first 19 authors' names, insert an ellipsis (but not ampersand), and then add the final author's name.

• Example:  Author, A. A., Author, B. B., Author, C. C., Author, D. D., Author, E. E., Author, F. F., Author, G. G., Author, H. H., Author, I. I., Author, J. J., Author, K. K., Author, L. L., Author, M. M., Author, N. N., Author, O. O., Author, P. P., Author, Q. Q., Author, R. R., Author, S. S., . . .  Author, Z. Z.

NOTE:  When a work has three or more authors, include the name of only the first author plus "et al." in every citation,  including the first citation, unless doing so would create ambiguity. For more information, see Sections 8.17 & 8.18 of the APA Style Manual (7th Edition).

• Paraphrase: (Westhues et al., 2001)
• Quotation:   ​(Westhues et al., 2001, p. 40)

Narrative citation:  Westhues et al. (2001)

A work is treated as having no author when its author is unknown or cannot reasonably be determined. In this case, move the title of the work to the author position (followed by a period), before the date of publication.

Generalized anxiety disorder. (2019).

In-Text Citations

• For works with an unknown author, include the title and year of publication in the in-text citation.
• Italicize the title in the in-text citation if the title of the work is italicized in the reference list.
• If the title of the work is not italicized in the reference list, use double quotation marks around the title.
• Capitalize these titles in the text using title case, even though sentence case is used in the reference list entry.
• If the title is long, shorten for in-text citation.

Book with no author: ( Interpersonal Skills , 2019)

Magazine article with no author: ("Understanding Sensory Memory," 2018)

Note : In the rare case the "Anonymous" is used for the author, treat it as the author's name (Anonymous, 2001). In the reference list, use the name Anonymous as the author.

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

• A  DOI  is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
• A  URL  specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

When to Include DOIs and URLs

Follow these guidelines for including DOIs and URLs in references:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• If a print work does not have a DOI, do not include any DOI or URL in the reference.
• If an online work has both a DOI and a URL, include only the DOI.
• For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
• For works without DOIs from most  academic research databases , do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
• Follow the current recommendations of the International DOI Foundation to format DOIs in the reference list, which as of the current  APA Style Manual  is as follows:

https://doi.org/xxxxx

• The string “https://doi.org/” is a way of presenting a DOI as a link, and “xxxxx” refers to the DOI number.
• The preferred format of the DOI has changed over time. Although older works use previous formats (e.g., “http:/dx.doi.org/” or “doi:” or “DOI:” before the DOI number), in your reference list, standardize DOIs into the current preferred format for all entries. For example, use  https://doi.org/10.1037/a0040251  in your reference even though that article, published in 2016, presented the number in an older format.
• Copy and paste the DOI or URL from your web browser directly into your reference list to avoid transcription errors. Do not change the capitalization or punctuation of the DOI or URL. Do not add line breaks manually to the hyperlink; it is acceptable if your word-processing program automatically adds a break or moves the hyperlink to its own line.
• Do not add a period after the DOI or URL because this may interfere with link functionality.
• Free DOI Lookup CrossRef currently provides a number of ways for you to locate a DOI.
• Resolve a DOI Type or paste a DOI name into the text box. Click Go. Your browser will take you to a Web page (URL) associated with that DOI name.

How to Cite a Research Paper in APA

Last Updated: October 19, 2022 Fact Checked

This article was co-authored by wikiHow Staff . Our trained team of editors and researchers validate articles for accuracy and comprehensiveness. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. There are 12 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 159,056 times. Learn more...

If you’re citing a research article or paper in APA style, you’ll need to use a specific citation format that varies depending on the source. Assess whether your source is an article or report published in an academic journal or book, or whether it is an unpublished research paper, such as a print-only thesis or dissertation. Either way, your in-text citations will need to include information about the author (if available) and the date when your source was published or written.

Sample Citations

Writing an In-Text Citation

• For example, you may write, “Gardener (2008) notes, ‘There are several factors to consider about lobsters’ (p. 199).”

• For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (Meek & Hill, 2015, p.13-14).”
• For articles with 3-5 authors, write out the names of all the authors the first time you cite the source. For example: (Hammett, Wooster, Smith, & Charles, 1928). In subsequent citations, write only the first author’s name, followed by et al.: (Hammett et al., 1928).
• If there are 6 or more authors for the paper, include the last name of the first author listed and then write "et al." to indicate that there are more than 5 authors.
• For example, you may write, "'This is a quote' (Minaj et al., 1997, p. 45)."

• For example, you may write, “‘The risk of cervical cancer in women is rising’ (American Cancer Society, 2012, p. 2).”

• For example, you may write, “‘Shakespeare may have been a woman’ (“Radical English Literature,” 2004, p. 45).” Or, “The paper notes, ‘There is a boom in Virgin Mary imagery’ (“Art History in Italy,” 2011, p. 32).”

• For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (“Iconography in Italian Frescos,” 2015, p.13-14).”

• For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (“Iconography in Italian Frescos,” 2015, p.145-146).”

• For example, you may write, “‘The effects of food deprivation are long-term’ (Mett, 2005, para. 18).”

Creating a Reference List Citation for a Published Source

• Material on websites is also considered “published,” even if it’s not peer-reviewed or associated with a formal publishing company.
• While academic dissertations or theses that are print-only are considered unpublished, these types of documents are considered published if they’re included in an online database (such as ProQuest) or incorporated into an institutional repository.

• For example, you may write, “Gardner, L. M.” Or, “Meek, P. Q., Kendrick, L. H., & Hill, R. W.”
• If there is no author, you can list the name of the organization that published the research paper. For example, you may write, “American Cancer Society” or “The Reading Room.”
• Formally published documents that don’t list an author or that have a corporate author are typically reports or white papers .

• For example, you may write, “Gardner, L. M. (2008).” Or, “American Cancer Society. (2015).”

• For example, you may write, “Gardner, L. M. (2008). Crustaceans: Research and data.” Or, “American Cancer Society. (2015). Cervical cancer rates in women ages 20-45.”

• For example, for a journal article, you may write, “Gardner, L. M. (2008). Crustaceans: Research and data. Modern Journal of Malacostracan Research, 25, 150-305.”
• For a book chapter, you could write: “Wooster, B. W. (1937). A comparative study of modern Dutch cow creamers. In T. E. Travers (Ed.), A Detailed History of Tea Serviceware (pp. 127-155). London: Wimble Press."

• For example, you may write, “Kotb, M. A., Kamal, A. M., Aldossary, N. M., & Bedewi, M. A. (2019). Effect of vitamin D replacement on depression in multiple sclerosis patients. Multiple Sclerosis and Related Disorders, 29, 111-117. Retrieved from PubMed, https://www.ncbi.nlm.nih.gov/pubmed/30708308.
• If you’re citing a paper or article that was published online but did not come from an academic journal or database, provide information about the author (if known), the date of publication (if available), and the website where you found the article. For example: “Hill, M. (n.d.). Egypt in the Ptolemaic Period. Retrieved from https://www.metmuseum.org/toah/hd/ptol/hd_ptol.htm”

Citing Unpublished Sources in Your Reference List

• Print-only dissertations or theses.
• Articles or book chapters that are in press or have been recently prepared or submitted for publication.
• Papers that have been rejected for publication or were never intended for publication (such as student research papers or unpublished conference papers).

• If the paper is currently being prepared for publication, include the author’s name, the year when the current draft was completed, and the title of the article in italics, followed by “Manuscript in preparation.” For example: Wooster, B. W. (1932). What the well-dressed man is wearing. Manuscript in preparation.
• If the paper has been submitted for publication, format the citation the same way as if it were in preparation, but instead follow the title with “Manuscript submitted for publication.” For example: Wooster, B. W. (1932). What the well-dressed man is wearing. Manuscript submitted for publication.
• If the paper has been accepted for publication but is not yet published, replace the date with “in press.” Do not italicize the paper title, but do include the title of the periodical or book in which it will be published and italicize that. For example: Wooster, B. W. (in press). What the well-dressed man is wearing. Milady’s Boudoir.

• If the paper was written for a conference but never published, your citation should look like this: Riker, W. T. (2019, March). Traditional methods for the preparation of spiny lobe-fish. Paper presented at the 325th Annual Intergalactic Culinary Conference, San Francisco, CA.
• For an unpublished paper written by a student for a class, include details about the institution where the paper was written. For example: Crusher, B. H. (2019). A typology of Cardassian skin diseases. Unpublished manuscript, Department of External Medicine, Starfleet Academy, San Francisco, CA.

• For example, you may write, “Pendlebottom, R. H. (2011). Iconography in Italian Frescos (Unpublished doctoral dissertation). New York University, New York, United States.”

About This Article

To cite a research paper in-text in APA, name the author in the text to introduce the quote and put the publication date for the text in parentheses. At the end of your quote, put the page number in parentheses. If you don’t mention the author in your prose, include them in the citation. Start the citation, which should come at the end of the quote, by listing the author’s last name, the year of publication, and the page number. Make sure to put all of this information in parentheses. If there’s no author, use the name of the organization that published the paper or the first few words from the title. To learn how to cite published and unpublished sources in your reference list, keep reading! Did this summary help you? Yes No

Origination of APA Style

• Where did APA Style come from?

Commonly Used APA Related Terms

Abstract : Abstract is a brief synopses of article. It provides a brief but comprehensive summary of the article. 

Citing : In the context of academic writing, citing is the act of acknowledging the sources of information you have used when writing your work.

Citation:  A citation gives credit to a source, and contains publication information such as author(s), title and date.

DOI (digital object identifier): It is a unique alphanumeric string assigned to a digital object, mainly a scholarly article, to provide a persistent link to its location on the internet. 

In-Text Citation : It is a brief note that appears within the body of the paper and briefly identifies the cited work by its author and date of publication. An in-text citation should always match the corresponding entry in the reference list at the end of paper.

Paraphrasing : A paraphrase restates another’s idea (or your own previously published idea) in your own words. 

Plagiarism : It is the act of presenting the words, ideas, or images of another as your own; it denies creators of content the credit they are due. 

Quoting : It is the act of reproducing the exact wording used by the original author. Direct quotations appear within quotation marks and end with a citation.

Reference : It contains details about one cited work, generally including four elements:  author, date, title, and source.  

Reference List : It identifies all the sources you cited in the text of your paper. It generally is at the end of the paper and definitely on a new page after the text of your paper. 

APA Style is the most common writing style used in college and career. Its purpose is to promote excellence in communication by helping writers create clear, precise, and inclusive sentences with a straightforward scholarly tone. It addresses areas of writing such as how to

• format a paper so it looks professional;
• credit other people’s words and ideas via citations and references to avoid plagiarism; and
• describe other people with dignity and respect using inclusive, bias-free language.

APA Style is primarily used in the behavioral sciences, which are subjects related to people, such as psychology, education, and nursing. It is also used by students in business, engineering, communications, and other classes. Students use it to write academic essays and research papers in college, and professionals use it to conduct, report, and publish scientific research.

In addition, APA Style provides you with a powerful tool that will hep you avoid deliberate or unintentional plagiarism. Please review the Avoiding Plagiarism Guide created by the APA experts to understand what two common types of plagiarism are and how to avoid them. 

Why is learning citations important? Citations help readers understand where the information used in your paper comes from, enabling them to trace the path of that information. When readers wish to explore a specific point or reference cited in the text, citations make it easier by providing information about your sources in a standardized format.

Besides showing readers where you obtained information, using citations also has a strong ethical purpose. In academic writing, it is important to credit ideas that are not your own. Citations allow you to integrate the ideas of others with your own thoughts in a fair and honest way.

The reference formats for APA Style manuals are as follows:

APA Style provides a foundation for effective scholarly communication because it helps authors present their ideas in a clear and concise, and organized manner.  Uniformity and consistency enable readers to (a) focus on the ideas being presented rather than formatting and (b) scan works quickly for key points, findings, and sources. When style works best, ideas flow logically, sources are credited appropriately, and papers are organized predictably and consistently. 

Students are encouraged to first learn about APA Style by reading works written in APA Style. A couple of guides created by APA experts from the American Psychological Association can help you with that:

Anatomy of a Journal Article   https://apastyle.apa.org/instructional-aids/anatomy-journal-article.pdf

Scholarly journal articles share a common anatomy or structure. Each part of an article serves a specific purpose. The handout of  Anatomy of a Journal Article explains how journal articles are structured and how to become more efficient at reading and understanding them. Understanding the structure of a scholarly article and the purpose of each part helps you grasp a strategy called targeted reading. Targeted reading means to read specific sections of research articles first to determine if the article seems useful for your research topic. This way you will save time, find useful article faster, and choose which articles to read in full.

Reading and Understanding Abstracts https://apastyle.apa.org/instructional-aids/reading-abstracts.pdf

Abstracts are short summaries of scientific research articles. The handout of Reading & Understanding Abstracts explains the definition and purpose of abstracts and the benefits of reading them, including analysis of a sample abstract. The skill of reading and understanding abstracts of scholarly articles not only saves time but also helps you conduct better research and write more effectively.

APA Style Writing Principles https://apastyle.apa.org/instructional-aids/writing-principles.pdf

The poster created by APA experts shows the three main principles of APA Style: clarity, precision, and inclusion and lists steps on how to achieve them. As a student writer, you always should write your academic paper with clarity, precision, and inclusion. 

Research Article Activity https://apastyle.apa.org/instructional-aids/apa-style-research-activity.pdf

Reading research articles is not an easy task for you as a student. The Research Article Activity designed by APA Style experts aims to make it easy to read and understand a scholarly article. This activity worksheet helps you find, cite, analyze, and summarize a research article. Completing this activity breaks down a lengthy research article into easily understandable chunks. This way helps you better understand the study in the article before you write about it.

APA Formatting and Citation (7th Ed.) | Generator, Template, Examples

Published on November 6, 2020 by Raimo Streefkerk . Revised on January 17, 2024.

The 7th edition of the APA Publication Manual provides guidelines for clear communication , citing sources , and formatting documents. This article focuses on paper formatting.

Generate accurate APA citations with Scribbr

Throughout your paper, you need to apply the following APA format guidelines:

• Set page margins to 1 inch on all sides.
• Double-space all text, including headings.
• Indent the first line of every paragraph 0.5 inches.
• Use an accessible font (e.g., Times New Roman 12pt., Arial 11pt., or Georgia 11pt.).
• Include a page number on every page.

Let an expert format your paper

Our APA formatting experts can help you to format your paper according to APA guidelines. They can help you with:

• Margins, line spacing, and indentation
• Font and headings
• Running head and page numbering

Table of contents

How to set up apa format (with template), apa alphabetization guidelines, apa format template [free download], page header, headings and subheadings, reference page, tables and figures, frequently asked questions about apa format.

Prevent plagiarism. Run a free check.

References are ordered alphabetically by the first author’s last name. If the author is unknown, order the reference entry by the first meaningful word of the title (ignoring articles: “the”, “a”, or “an”).

Why set up APA format from scratch if you can download Scribbr’s template for free?

Student papers and professional papers have slightly different guidelines regarding the title page, abstract, and running head. Our template is available in Word and Google Docs format for both versions.

• Student paper: Word | Google Docs
• Professional paper: Word | Google Docs

In an APA Style paper, every page has a page header. For student papers, the page header usually consists of just a page number in the page’s top-right corner. For professional papers intended for publication, it also includes a running head .

A running head is simply the paper’s title in all capital letters. It is left-aligned and can be up to 50 characters in length. Longer titles are abbreviated .

APA headings have five possible levels. Heading level 1 is used for main sections such as “ Methods ” or “ Results ”. Heading levels 2 to 5 are used for subheadings. Each heading level is formatted differently.

Want to know how many heading levels you should use, when to use which heading level, and how to set up heading styles in Word or Google Docs? Then check out our in-depth article on APA headings .

The title page is the first page of an APA Style paper. There are different guidelines for student and professional papers.

Both versions include the paper title and author’s name and affiliation. The student version includes the course number and name, instructor name, and due date of the assignment. The professional version includes an author note and running head .

For more information on writing a striking title, crediting multiple authors (with different affiliations), and writing the author note, check out our in-depth article on the APA title page .

The abstract is a 150–250 word summary of your paper. An abstract is usually required in professional papers, but it’s rare to include one in student papers (except for longer texts like theses and dissertations).

The abstract is placed on a separate page after the title page . At the top of the page, write the section label “Abstract” (bold and centered). The contents of the abstract appear directly under the label. Unlike regular paragraphs, the first line is not indented. Abstracts are usually written as a single paragraph without headings or blank lines.

Directly below the abstract, you may list three to five relevant keywords . On a new line, write the label “Keywords:” (italicized and indented), followed by the keywords in lowercase letters, separated by commas.

APA Style does not provide guidelines for formatting the table of contents . It’s also not a required paper element in either professional or student papers. If your instructor wants you to include a table of contents, it’s best to follow the general guidelines.

Place the table of contents on a separate page between the abstract and introduction. Write the section label “Contents” at the top (bold and centered), press “Enter” once, and list the important headings with corresponding page numbers.

The APA reference page is placed after the main body of your paper but before any appendices . Here you list all sources that you’ve cited in your paper (through APA in-text citations ). APA provides guidelines for formatting the references as well as the page itself.

Creating APA Style references

Play around with the Scribbr Citation Example Generator below to learn about the APA reference format of the most common source types or generate APA citations for free with Scribbr’s APA Citation Generator .

Formatting the reference page

Write the section label “References” at the top of a new page (bold and centered). Place the reference entries directly under the label in alphabetical order.

Finally, apply a hanging indent , meaning the first line of each reference is left-aligned, and all subsequent lines are indented 0.5 inches.

Tables and figures are presented in a similar format. They’re preceded by a number and title and followed by explanatory notes (if necessary).

Use bold styling for the word “Table” or “Figure” and the number, and place the title on a separate line directly below it (in italics and title case). Try to keep tables clean; don’t use any vertical lines, use as few horizontal lines as possible, and keep row and column labels concise.

Keep the design of figures as simple as possible. Include labels and a legend if needed, and only use color when necessary (not to make it look more appealing).

Check out our in-depth article about table and figure notes to learn when to use notes and how to format them.

The easiest way to set up APA format in Word is to download Scribbr’s free APA format template for student papers or professional papers.

Alternatively, you can watch Scribbr’s 5-minute step-by-step tutorial or check out our APA format guide with examples.

APA Style papers should be written in a font that is legible and widely accessible. For example:

• Times New Roman (12pt.)
• Arial (11pt.)
• Calibri (11pt.)
• Georgia (11pt.)

The same font and font size is used throughout the document, including the running head , page numbers, headings , and the reference page . Text in footnotes and figure images may be smaller and use single line spacing.

You need an APA in-text citation and reference entry . Each source type has its own format; for example, a webpage citation is different from a book citation .

Use Scribbr’s free APA Citation Generator to generate flawless citations in seconds or take a look at our APA citation examples .

Yes, page numbers are included on all pages, including the title page , table of contents , and reference page . Page numbers should be right-aligned in the page header.

To insert page numbers in Microsoft Word or Google Docs, click ‘Insert’ and then ‘Page number’.

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

Reference List: Basic Rules

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.

This resourse, revised according to the 7 th  edition APA Publication Manual, offers basic guidelines for formatting the reference list at the end of a standard APA research paper. Most sources follow fairly straightforward rules. However, because sources obtained from academic journals  carry special weight in research writing, these sources are subject to special rules . Thus, this page presents basic guidelines for citing academic journals separate from its "ordinary" basic guidelines. This distinction is made clear below.

Note:  Because the information on this page pertains to virtually all citations, we've highlighted one important difference between APA 6 and APA 7 with an underlined note written in red.  For more information, please consult the   Publication Manual of the American Psychological Association , (7 th  ed.).

Formatting a Reference List

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.

Your references should begin on a new page separate from the text of the essay; label this page "References" in bold, centered at the top of the page (do NOT underline or use quotation marks for the title). All text should be double-spaced just like the rest of your essay.

Basic Rules for Most Sources

• All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.
• All authors' names should be inverted (i.e., last names should be provided first).
• For example, the reference entry for a source written by Jane Marie Smith would begin with "Smith, J. M."
• If a middle name isn't available, just initialize the author's first name: "Smith, J."
• Give the last name and first/middle initials for all authors of a particular work up to and including 20 authors ( this is a new rule, as APA 6 only required the first six authors ). Separate each author’s initials from the next author in the list with a comma. Use an ampersand (&) before the last author’s name. If there are 21 or more authors, use an ellipsis (but no ampersand) after the 19th author, and then add the final author’s name.
• Reference list entries should be alphabetized by the last name of the first author of each work.
• For multiple articles by the same author, or authors listed in the same order, list the entries in chronological order, from earliest to most recent.
• Note again that the titles of academic journals are subject to special rules. See section below.
• Italicize titles of longer works (e.g., books, edited collections, names of newspapers, and so on).
• Do not italicize, underline, or put quotes around the titles of shorter works such as chapters in books or essays in edited collections.

Basic Rules for Articles in Academic Journals

• Present journal titles in full.
• Italicize journal titles.
• For example, you should use  PhiloSOPHIA  instead of  Philosophia,  or  Past & Present   instead of  Past and Present.
• This distinction is based on the type of source being cited. Academic journal titles have all major words capitalized, while other sources' titles do not.
• Capitalize   the first word of the titles and subtitles of   journal articles , as well as the   first word after a colon or a dash in the title, and   any proper nouns .
• Do not italicize or underline the article title.
• Deep blue: The mysteries of the Marianas Trench.
• Oceanographic Study: A Peer-Reviewed Publication

Please note:  While the APA manual provides examples of how to cite common types of sources, it does not cover all conceivable sources. If you must cite a source that APA does not address, the APA suggests finding an example that is similar to your source and using that format. For more information, see page 282 of the   Publication Manual of the American Psychological Association , 7 th  ed.

Unraveling the cellular and molecular mechanisms underlying tumoral processes is fundamental for the diagnosis and treatment of cancer. In this regard, three-dimensional (3D) cancer cell models more realistically mimic tumors compared to conventional 2D cell cultures and are more attractive for performing such studies. Nonetheless, the analysis of such architectures is challenging because most available techniques are destructive, resulting in the loss of biochemical information. On the contrary, surface-enhanced Raman spectroscopy (SERS) is a non-invasive analytical tool that can record the structural fingerprint of molecules present in complex biological environments. The implementation of SERS in 3D cancer models can be leveraged to track therapeutics, the production of cancer-related metabolites, different signaling and communication pathways, and to image the different cellular components and structural features. In this review, we highlight recent progress in the use of SERS for the evaluation of cancer diagnosis and therapy in 3D tumoral models. We outline strategies for the delivery and design of SERS tags and shed light on the possibilities this technique offers for studying different cellular processes, through either biosensing or bioimaging modalities. Finally, we address current challenges and future directions, such as overcoming the limitations of SERS and the need for the development of user-friendly and robust data analysis methods. Continued development of SERS 3D bioimaging and biosensing systems, techniques, and analytical strategies, can provide significant contributions for early disease detection, novel cancer therapies, and the realization of patient-tailored medicine.
