In-text citations are brief references in the running text that direct readers to the reference entry at the end of the paper. You include them every time you quote or paraphrase someone else’s ideas or words.

An APA in-text citation consists of the author’s last name and the year of publication (also known as the author-date system). If you’re citing a specific part of a source, you should also include a locator such as a page number or timestamp. For example: (Smith, 2020, p. 170) .

Parenthetical vs. narrative citation

The in-text citation can take two forms: parenthetical and narrative. Both types are generated automatically when citing a source with Scribbr’s APA Citation Generator.

• Parenthetical citation: According to new research … (Smith, 2020) .
• Narrative citation: Smith (2020) notes that …

Multiple authors and corporate authors

The in-text citation changes slightly when a source has multiple authors or an organization as an author. Pay attention to punctuation and the use of the ampersand (&) symbol.

Missing information

When the author, publication date or locator is unknown, take the steps outlined below.

Prevent plagiarism, run a free check.

APA references generally include information about the author , publication date , title , and source . Depending on the type of source, you may have to include extra information that helps your reader locate the source.

Reference examples

Citing a source starts with choosing the correct reference format. Use Scribbr’s Citation Example Generator to learn more about the format for the most common source types. Pay close attention to punctuation, capitalization, and italicization.

Generate APA citations for free

It is not uncommon for certain information to be unknown or missing, especially with sources found online. In these cases, the reference is slightly adjusted.

On the first line of the page, write the section label “References” (in bold and centred). On the second line, start listing your references in alphabetical order .

Apply these formatting guidelines to the APA reference page:

• Double spacing (within and between references)
• Hanging indent of ½ inch
• Legible font (e.g. Times New Roman 12 or Arial 11)
• Page number in the top-right header

Which sources to include

On the reference page, you only include sources that you have cited in the text (with an in-text citation ). You should not include references to personal communications that your reader can’t access (e.g. emails, phone conversations or private online material).

What is APA Style?

APA style was created by social and behavioral scientists to standardize scientific writing. APA style is most often used in:

• psychology,
• social sciences (sociology, business), and

If you're taking courses in any of these areas, be prepared to use APA style.

For in-depth guidance on using this citation style, refer to Publication Manual of the American Psychological Association , 7th ed. We have several copies available at the MJC Library at the call number  BF 76.7 .P83 2020 .

APA Style, 7th ed.

In October 2019, the American Psychological Association made radical changes its style, especially with regard to the format and citation rules for students writing academic papers. Use this guide to learn how to format and cite your papers using APA Style, 7th edition.

You can start by viewing the  video tutorial .

For help on all aspects of formatting your paper in APA Style, see   The Essentials  page on the APA Style website.

• sans serif fonts such as 11-point Calibri, 11-point Arial, or 10-point Lucida Sans Unicode, or
• serif fonts such as 12-point Times New Roman, 11-point Georgia, or normal (10-point) Computer Modern (the default font for LaTeX)
• There are exceptions for the  title page ,  tables ,  figures ,  footnotes , and  displayed equations .
• Margins :  Use 1-in. margins on every side of the page.
• Align the text of an APA Style  paper to the left margin . Leave the right margin uneven, or “ragged.”
• Do not use full justification for student papers.
• Do not insert hyphens (manual breaks) in words at the end of line. However, it is acceptable if your word-processing program automatically inserts breaks in long hyperlinks (such as in a DOI or URL in a reference list entry).
• Indent the first line of each paragraph of text 0.5 in . from the left margin. Use the tab key or the automatic paragraph-formatting function of your word-processing program to achieve the indentation (the default setting is likely already 0.5 in.). Do not use the space bar to create indentation. 
• There are exceptions for the  title page ,  section labels ,  abstract ,  block quotations ,  headings ,  tables and figures ,  reference list , and  appendices .

Paper Elements

Student papers generally include, at a minimum: 

• Title Page (2.3)
• Text (2.11)
• References  (2.12)

Student papers may include additional elements such as tables and figures depending on the assignment. So, please check with your teacher!

Student papers generally  DO NOT  include the following unless your teacher specifically requests it:

• Running head
• Author note

For complete information on the  order of pages , see the APA Style website.

Number your pages consecutively starting with page 1. Each section begins on a new page. Put the pages in the following order:

• Page 1: Title page
• Page 2: Abstract (if your teacher requires an abstract)
• Page 3: Text 
• References begin on a new page after the last page of text
• Footnotes begin on a new page after the references (if your teacher requires footnotes)
• Tables begin each on a new page after the footnotes (if your teacher requires tables) 
• Figures begin on a new page after the tables (if your teacher requires figures)
• Appendices begin on a new page after the tables and/or figures (if your teacher requires appendices)

Sample Papers With Built-In Instructions

To see what your paper should look like, check out these sample papers with built-in instructions.

APA Style uses five (5) levels of headings to help you organize your paper and allow your audience to identify its key points easily. Levels of headings establish the hierarchy of your sections just like you did in your paper outline.

APA tells us to use "only the number of headings necessary to differentiate distinct section in your paper." Therefore, the number of heading levels you create depends on the length and complexity of your paper.

See the chart below for instructions on formatting your headings:

Use Word to Format Your Paper:

Use Google Docs to Format Your Paper:

Placement:  The reference list  appears at the end of the paper, on its own page(s). If your research paper ends on page 8, your References begin on page 9.

Heading:  Place the section label References  in bold at the top of the page, centered.

Arrangement:  Alphabetize entries by author's last name. If source has no named author, alphabetize by the title, ignoring A, An, or The. (9.44-9.48)

Spacing:  Like the rest of the APA paper, the reference list is double-spaced throughout. Be sure NOT to add extra spaces between citations.

Indentation:  To make citations easier to scan, add a  hanging indent  of 0.5 in. to any citation that runs more than one line. Use the paragraph-formatting function of your word processing program to create your hanging indent.  

See Sample References Page (from APA Sample Student Paper):

Elements of Reference List Entries: (Chapter 9)

References generally have four elements, each of which has a corresponding question for you to answer:

• Author:   Who is responsible for this work? (9.7-9.12)
• Date:   When was this work published? (9.13-9.17)
• Title:   What is this work called? (9.18-9.22)
• Source:   Where can I retrieve this work? (9.23-9.37)

By using these four elements and answering these four questions, you should be able to create a citation for any type of source.

For complete information on all of these elements, checkout the APA Style website.

This infographic shows the first page of a journal article. The locations of the reference elements are highlighted with different colors and callouts, and the same colors are used in the reference list entry to show how the entry corresponds to the source.

To create your references, you'll simple look for these elements in your source and put them together in your reference list entry.

Sometimes you won't be able to find all the elements required for your reference. In that case, see the  instructions in Table 9.1 of the APA style manual in section 9.4 or the APA Style website below:

• Direct Quotation of Material Without Page Numbers

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:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• 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.
• For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. (See APA Section 9.30 for more information). 
• If the URL is no longer working or no longer provides readers access to the content you intend to cite, try to find an archived version using the Internet Archive , then use the archived URL. If there is no archived URL, do not use that resource.

Format of DOIs and URLs:

Your DOI should look like this: 

https://doi.org/10.1037/a0040251

Follow these guidelines from the APA Style website.

APA Style uses the  author–date citation system , in which a brief in-text citation points your reader to the full reference list entry at the end of your paper. The in-text citation appears within the body of the paper and briefly identifies the cited work by its author and date of publication. This method enables your reader to locate the corresponding entry in the alphabetical reference list at the end of your paper.

Each work you cite  must  appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix) except for the following (See APA, 8.4):

• Personal communications (8.9)
• General mentions of entire websites, whole periodicals (8.22), and common software and apps (10.10) in the text do not require a citation or reference list entry.
• The source of an epigraph does not usually appear in the reference list (8.35)
• Quotations from your research participants do not need citations or reference list entries (8.36)
• References included in a statistical meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis (9.52).

Formatting Your In-Text Citations

Parenthetical and Narrative Citations: ( See APA Section  8.11)

In APA style you use the author-date citation system for citing references within your paper. You incorporate these references using either a  parenthetical   or a  narrative  style.

Parenthetical Citations

• In parenthetical citations, the author name and publication date appear in parentheses, separated by a comma. (Jones, 2018)
• A parenthetical citation can appear within or at the end of a sentence.
• When the parenthetical citation is at the end of the sentence, put the period or other end punctuation after the closing parenthesis.
• If there is no author, use the first few words of the reference list entry, usually the "Title" of the source: ("Autism," 2008) See APA 8.14
• When quoting, always provide the author, year, and specific page citation or paragraph number for nonpaginated materials in the text (Santa Barbara, 2010, p. 243).  See APA 8.13
• For most citations, the parenthetical reference is placed BEFORE the punctuation: Magnesium can be effective in treating PMS (Haggerty, 2012).

Narrative Citations 

In narrative citations, the author name or title of your source appears within your text and the publication date appears in parentheses immediately after the author name. 

• Santa Barbara (2010) noted a decline in the approval of disciplinary spanking of 26 percentage points from 1968 to 1994.

About this Page

This page contains information on the style and format of papers according to APA 7th edition using the Concise Guide to APA Style: The Official APA Style for Students .

• APA Style and Grammar Guidelines

APA Style papers should have the same style and size of font throughout the text of the paper (title page to reference page). APA considers the following fonts acceptable: 11- point Calibri, 11-point Arial, 10-point Lucida Sans Unicode, 12-point Times New Roman, 11-point Georgia, or 10-point Computer Modern. It is recommended that you check with your instructor to see if they have a preferred font style.

(See section 1.18 of the Concise Guide to APA Style )

The first line of every paragraph in the text of your paper and every reference on your reference page is indented (hit the tab key once). The remaining lines are left flush with the left-hand margin of the paper (this is known as a "hanging indent").

Other Format Guidelines

Page numbers : Title page through reference pages are numbered using Arabic numerals;  place each number in the top right corner of the page.

Running heads: Are NOT required in student papers, but you should still check with your instructor to see if they wish them to be used.

Dashes: APA uses em dashes (long dash) and en dashes (short dash). See section 4.6 of the Concise Guide to APA Style for more information.

Lines and Margins

APA Style papers should have double-spaced text throughout the entire paper (including quotations and references). To make your paper double-spaced in Microsoft Word, highlight the text you want double-spaced, and then click Layout . Next, click on the arrow to the right of the word Paragraph (a pop-up appears). From the drop-down menu under Line Spacing , select Double (default choice is Multiple ) and click OK .

APA Style papers use 1 inch margins all around (top to bottom and left to right). Margins in Microsoft Word are set to 1 inch by default. If you are unsure, you can check your margins by clicking Layout, and clicking Margins. Once the drop-down menu appears, make sure Normal is selected to ensure you have 1 inch margins all around your paper.

(See sections 1.20 and 1.21 of the Concise Guide to APA Style )

APA Style recommends ONE space after a period when the period ends a sentence, separates parts of a reference list entry, or follows initials in names (J.B. Jones).

Do NOT put a space after a period when the period is part of an internal abbreviations (U.S. or a.m.)

Do NOT use periods for the abbreviation of state, province, or territory names (AZ; KS; BC); capital letter abbreviations and acronyms (APA, AMA, EPA); for abbreviations of academic degrees (PhD, MD, DO); or for abbreviations of metric and nonmetric measurements (cm, hr, kg,). Note: Use a period when abbreviating "inch" or "inches" (in.) or else it could be misread.

(See sections 4.1 and 4.2 of the Concise Guide to APA Style )

Sentence Case vs. Title Case

Sentence case is where most words in a sentence are going to be lower case.

The EXCEPTIONS are the first word in a title, heading, or sub-title ; proper nouns ; the first word after an em dash, semi-colon, or end punctuation; and any noun followed by a letter or number.

Title case is where major words are capitalized while minor words are lower case.

In APA style, major words are nouns, verbs, adjectives, pronouns, adverbs, or any word that is four letters or longer.

Minor words are articles, short prepositions, and conjunctions that are three letters or less.

(See section 5.7 of the Concise Guide to APA Style )

Paraphrasing

Refers to restating someone else's ideas or findings into your own words. Paraphrasing allows you to summarize information from one or more sources, compare and contrast information from multiple sources, and focus on the most important information from each source.

It is BEST to paraphrase information whenever possible rather than using direct quotations.

Paraphrased information must be cited in-text with either a parenthetical or narrative citation.

(See sections 8.23 and 8.24 of the Concise Guide to APA Style)

Reproduce words EXACTLY as written from another work (including your own). Quotations are best used in papers for when you want to reproduce an exact definition, when an author of a work has said something memorable, or when you want to respond to the exact wording (something someone said) from an author in your paper.

When not using a quotation for one of the above reasons, it is best to paraphrase information. Additionally, you should check with your instructor to see if they limit the number of quotations you are allowed to use.

Quotations must be cited in-text with either a parenthetical or narrative citation.

Short quotations consist of 40 words or less and should be incorporated into the text of your paper with quotation marks.

Long quotations consists of 40 words or more and do not use quotations marks. Instead, they should be incorporated into your paper as a block quotation. Block quotations begin on a new line, are double-spaced, and are indented 0.5 inches from the left hand margin of your paper.

(See sections 8.25 - 8.33 of the Concise Guide to APA Style)

Heading Levels

Heading Levels or "headings" are a way to organize information in APA papers and convey it clearly ( think of headings as "sections" and "subsections"). There are five levels of headings in APA Style, although for undergraduates it is rare to need to go past a Level 2 headings. If you are unsure if you need to use headings, check with your instructor.

Note: Do NOT label an introduction as "Introduction" in APA papers. The title of your paper acts as a de facto Level 1 Heading.

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).

Common Citations and References in APA Style (7th Ed.)

APA Common Citations & References (7th Ed.) PDF

The American Psychological Association (APA) established writing and documentation guidelines in 1929, so readers could easily understand the major points and findings in scientific research. Today, APA Style is used across the disciplines as a standard style for academic and professional writing. APA Style helps writers think critically, communicate clearly and precisely, and document sources ethically. This tutorial on APA citations and references follows the guidelines of the Publication Manual of the American Psychological Association seventh edition .

Citations and references are forms of documentation. We must document the ideas, theories, definitions, data, images, and other information in our writing that originated with other authors, researchers, and artists. For example, our work must include documentation when we quote, paraphrase, or summarize another’s ideas or when using data from others’ research. Documentation means including select information about a source “in text” and including additional bibliographic information about that source in a “reference list entry.” In APA Style, for every retrievable source cited in text, there is a corresponding reference list entry with that retrieval information.

Documentation is how we establish our credibility as researchers and writers. It is how we write ethically and with integrity. Writing often involves using the ideas, theories, definitions, data, and images of others in order to support or refute our theses. Documentation is how we give credit to others for their contributions to our work. Documenting sources also differentiates our original ideas from the source contributions and enables readers to locate the original source to learn more about it. Documenting sources with in-text citations and reference list entries also prevents plagiarism, which “is the act of presenting the words, ideas, or images of another as your own” (APA, 2020, p. 254).

APA Style in-text citations use the author-date system. In this APA Style in-text citations use the author-date system. In this system, the citation identifies a source used in the “text” (the body of a piece of writing) by providing the source’s author and the date of publication. Additional rules apply for in-text citations for varying source types and paraphrasing, but there are two primary types of in-text citations: narrative and parenthetical .

In narrative citations, the author’s name is part of a sentence and usually appears in a signal phrase that introduces the quoted, paraphrased, or summarized information. The second part of the citation, the publication year, then appears in parentheses immediately following the author’s name. Here is an example:

• Smith (2010) recognized that more online learning opportunities are needed to reach marginalized high school students and decrease the dropout rate.

When citing a quotation using a narrative citation, the author’s name is used in the sentence, the date is given in parentheses after the author’s name, and the specific part of the source where the quote appears such the page, paragraph, time stamp on a video, or bar on a graph goes in parentheses after the quote and before any punctuation. Here are two examples:

• Smith (2010) stressed, “The importance of dedicated study time for online courses is crucial for student success” (p. 3).
• In his TEDX Talk video, Mulvey (2013) said, “Time is too long. Space is too large” (6:18).

In parenthetical citations, the author-date information goes after the paraphrase in parentheses as in the following example:

• Online learning opportunities are needed to reach marginalized high school students and decrease the dropout rate (Smith, 2010) .

For a quotation, the parenthetical citation contains the author and date, and it also contains the specific part of the source such as the page or paragraph number or the timestamp of a video as in this example:

• Many researchers have agreed: “Online education is a viable way to help working adults earn a college degree, but it is not for everyone” (Smith, 2010, p. 4) .

An author may be an individual, multiple people, or a group such as an organization, company, or governmental agency. In an in-text citation, the format is to use the author or authors’ last names or the group author name. See No Author if a source does not specify an author.

• Individual Author: (Hannah, 2010)
• Multiple Authors: (Hannah & Lay, 2015); (Hannah, Lay, & Sleder, 2010)
• Group Author: (Hannah and Lay Company, 2020)

The URL, which stands for Uniform Resource Locator and is the web address for a source is not part of an in-text citation except in the rare cases that the URL is also the author’s name such as Drugs.com: (Drugs.com, n.d.).

The in-text citation for a quotation includes the part of the source where the information is found. Page numbers are common in printed books and articles; however, for electronic sources without page numbers, you will need to provide another way for a reader to locate the original passage being quoted. The following options are acceptable:

• Paragraph number: (Mackenzie, 2018, para. 1)
• Heading or section name: (Mackenzie, 2018, Highlands section). In this example, the information being cited can be found on the source website or page under a section named “Highlands.”
• Both section and paragraph: (Mackenzie, 2018, Highlands section, para. 1)
• For audiovisual works, provide the time stamp of when the quoted words begin: (Mulvey, 2013, 6:18).

A reference list entry should be provided for each source cited in text. Reference list entries have four elements: author, date, title, and source. The “source” here is the publication where the information was published such as a website, book, or periodical. Each element of the reference answers a question:

• Author: Who is responsible for this work?
• Date: When was this work published?
• Title: What is this work called?
• Source: Where can I retrieve this work?

Reference entries and in-text citations correspond: The author or title given in the in-text citation is the first element of the reference entry. Example reference entries are provided in the Common Citations and References section of this resource. The following formatting requirements apply to the reference list:

• Label the reference list References in bold font, centered at the top of the page.
• Double-space all reference list entries. Also use double spacing within entries. Do not use additional spacing between entries.
• Reference entries are not numbered or bulleted.
• Use a hanging indent for all references, so the first line of the entry is against the left margin and subsequent lines of the entry are indented 0.5 in.
• Alphabetize the entries according to the author’s last name. If the entry does not include an author, begin the entry with the title followed by the year in parentheses, and alphabetize according to the first significant word of the title. If the title begins with the words “A,” “An,” or “The,” alphabetize using the next word in the title. Example: The title The Whales in the Ocean would be alphabetized using the letter “W” because “Whales” is the first significant word.

Resources available online have URLs, which are web links, or DOIs, which are unique strings of numbers that provide persistent and reliable links to resources. Here are some basic guidelines for URLs and DOIs in reference entries:

• If a source has a DOI, include it in the reference entry. Some print texts also have DOIs. The DOI is often given near the copyright information at the beginning of a text.
• Present DOIs and URLs as hyperlinks in the reference entry. Hyperlinks begin http:// or https:// . DOIs will begin https://doi.org/ . It is acceptable to use the shortDOI® Service to shorten long DOIs and an URL shortening service such as https://bitly.com/ to shorten URLs.
• All hyperlinks should be live and may appear using the automatic formatting of the word processing program (for example in blue font and underlined), or they may appear in standard black font without an underline, but papers read online should have clickable, live links.
• Do not include additional words before the hyperlink such as “Retrieved from” or “DOI.” Exception : If a characteristics of the source is that it is updated regularly, such a reference book with a group author (dictionary, encyclopedia, thesaurus) or a Facebook page, a retrieval date would provide valuable information to a reader who tries to locate your source and sees different content. In the reference, include the date you accessed the source in the following format for the URL element of the reference: Retrieved Month day, Year, from URL.

Note . When using two or more sources with the same author and year, add lowercase letters after the year (2015a, 2015b, etc.). First alphabetize the references by author name and then by title to determine which is “a” and which is “b.” Then also add the letters to the corresponding in-text citations. If the site name is the same as the author, omit the site name element from the reference.

Reference for a webpage with no individual or group author

Title of page . (Year, Month XX or n.d. if a date isn’t available). Site Name. URL or Retrieved Month XX, Year from URL if citing a page that is regularly updated.

Sometimes there is missing information when formatting in-text citations and references. The following serves as guidance on how to handle those situations.

Missing month and/or day; missing volume and/or issue number; other missing information from template of reference citation : If a reference entry template shows to include information that is not available, omit the missing elements from the entry.

If a work does not specify an author, use the title in place of the author.

In-Text-Citation

• For a paraphrase from an article with no author: (“Whales in the Ocean,” 2020)
• For a quotation from a book with no author: ( Plant-Based Cooking , 2020, para. 9)

Reference Entry

• The reference list entry for an article with no author begins with the title in sentence case (capitalizing the first word only and any proper nouns):

Whales in the ocean. (2020). Ocean Life Magazine . https://www.oceanlife.com

• The reference list entry for a book, webpage, or other whole work without an author begins with the title in sentence case and italics:

Plant-based cooking . (2020). https://www.plant-basedcookingebook.com

• Only use “Anonymous” as the author if the work specifically names the author as “Anonymous”: (Anonymous, n.d.).

If no date is provided on the source, use n.d. in the date spot for both in-text citations and reference list entries. For example, an in-text citation would look like this: (Hendrix, n.d.).

Primary sources are original reports, findings, and research studies. Secondary sources are works that refer to primary sources and other secondary sources. If you are using a secondary source for your research, and it refers to another source or a primary source, whenever possible, locate the original source of the desired quote or paraphrase. If the original source is not available, use this “as cited in” method by citing the secondary source that you have while still attributing the quote in text to the original author or source.

In-Text Citation for Primary Sources

• Parenthetical: (Wright, 2012, as cited in Bragdon, 2013, p. 223).
• Narrative: Wright’s report (2012, as cited in Bragdon, 2013) showed that “obesity research indicates people need to drink more water” (p. 223).

Note . Omit the year for the primary source from the citation if the year is unknown.*

• Parenthetical: (Wright, 2012, as cited in Bragdon, 2013).
• Narrative: Wright (2012, as cited in Bragdon, 2013) showed dehydration was a common problem for those with obesity.

Reference for the Secondary Source

Follow the template for the type of source it is. The example shows the format for a journal article without a URL or DOI.

Bragdon, A. A. (2013). Obesity research. Medical Journal 23 (4), 223-227.

Note . Only list the source named after the “as cited in” phrase on the reference list.

Multiple Authors

Two authors.

For in-text citations, cite both names every time:

• (Rios & Sexton, 2010) or Rios and Sexton (2010) contend . . .

Note . The ampersand (&) is used between two authors when their names are written in parentheses but not when the names are written in the narrative of the sentence.

For reference list entries, cite both authors’ names (with the ampersand [&] between the names):

Rios, C. A. & Sexton, A. (2010). Fun and easy APA . Oxbow River Press.

Three or More Authors

For in-text citations, cite only the first author followed by et al.:

• (Cairns et al., 2019)
• Cairns et al. (2019) studied . . .

Note . Et al. is a Latin abbreviation for “and others.”

For a reference list entry, cite the first 20 author names. Use an ampersand (&) before the last author’s name:

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.

For 21 or more authors, use three spaced ellipsis points ( . . . ) after the 19th author and then cite the last author’s name without an ampersand (&):

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, W. W.

Authors With the Same Surname

If you have two or more different sources that have authors with the same surname, include the author’s first name initial in the in-text citation for the source used even if the date is different like this: (D. Martinez, 2001).

A narrative citation would look like this:

• D. Martinez (2001) disagreed with S. Martinez (2003) in the findings . . .

In the reference list, D. Martinez would be alphabetized before S. Martinez.

Same Author and Year

To tell references and in-text citations apart when the author and year are the same, add lowercase letters after the year (2011a, 2011b, etc.). On the references list, first list the references in alphabetical order by the authors’ last names, then alphabetize the references by the title to determine which is “a” and which is “b.”

Hood, R. M. (2011b). The writing process [Video]. YouTube. http://www.youtube.com/abc-thewritingprocess

Then, add the letters to the corresponding in-text citations: (Hood, 2011a) (Hood, 2011b).

Being responsible while researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own assignment. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project (i.e., citing), which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the Latin word, plagiare , which means “to kidnap.” The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author (American Psychological Association, 2020 p. 21). Plagiarism can be illegal and there can be serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including citations and references in your research project. Want to make them quickly and easily? Try the Citation Machine citation generator, which is found on our homepage.

All about citations & references

Citations and references should be included anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation and a reference. This guide explains how to make them.

APA style citations are added in the body of a research paper or project and references are added to the last page.

Citations , which are called in-text citations, are included when you’re adding information from another individual’s work into your own project. When you add text word-for-word from another source into your project, or take information from another source and place it in your own words and writing style (known as paraphrasing), you create an in-text citation. These citations are short in length and are placed in the main part of your project, directly after the borrowed information.

References are found at the end of your research project, usually on the last page. Included on this reference list page is the full information for any in-text citations found in the body of the project. These references are listed in alphabetical order by the author's last name.

An APA in-text citation includes only three items: the last name(s) of the author(s), the year the source was published, and sometimes the page or location of the information. References include more information such as the name of the author(s), the year the source was published, the full title of the source, and the URL or page range.

Why is it important to include citations & references

Including APA citations and references in your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher. You’re showing readers that you were able to find valuable, high-quality information from other sources, place them into your project where appropriate, all while acknowledging the original authors and their work.

Common ways students and scholars accidentally plagiarize

Believe it or not, there are instances when you could attempt to include in-text and full references in the appropriate places, but still accidentally plagiarize. Here are some common mistakes to be aware of:

Mistake #1 - Misquoting sources: If you plan to use a direct quote, make sure you copy it exactly as is. Sure, you can use part of the full quote or sentence, but if you decide to put quotation marks around any words, those words should match exactly what was found in the original source. Here’s a line from The Little Prince , by Antoine de Saint-Exupéry:

“Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.”

Here’s an acceptable option:

“Grown-ups never understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Here’s a misquote:

“Grown-ups barely ever understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Notice the slight change in the words. The incorrect phrasing is an instance of accidental plagiarism.

Mistake #2 - Problems with paraphrasing: When we paraphrase, we restate information using our own words and writing style. It’s not acceptable to substitute words from the original source with synonyms.

Let’s use the same sentence from The Little Prince .

A correct paraphrase could be:

de Saint-Exupéry (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything. It’s too bad adults are unable to comprehend anything on their own (p. 3).

An incorrect paraphrase would be:

de Saint-Exupéry (1943) shares that adults never understand anything by themselves, and it is exhausting for kids to be always and forever clarifying things to them (p.3).

Notice how close the incorrect paraphrase is from the original. This is an instance of accidental plagiarism.

Make sure you quote and paraphrase properly in order to prevent accidental plagiarism.

If you’re having a difficult time paraphrasing properly, it is acceptable to paraphrase part of the text AND use a direct quote. Here’s an example:

de Saint-Exupery (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything, and “it is tiresome for children to be always and forever explaining things to them” (p. 3).

Information About APA

Who created it.

The American Psychological Association is an organization created for individuals in the psychology field. With close to 121,000 members, they provide educational opportunities, funding, guidance, and research information for everything psychology-related. They also have numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating their own specific citation and reference style. Today, this format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information . This guide covers general information about the style, but is not affiliated with the American Psychological Association.

Why was this style created?

This format was first developed in 1929 to form a standardized way for researchers in science fields to document their sources. Prior to the inception of these standards and guidelines, individuals were recognizing the work of other authors by including bits and pieces of information in random order. There wasn’t a set way to format citations and references. You can probably imagine how difficult it was to understand the sources that were used for research projects!

Having a standard format for citing sources allows readers to glance at a citation or APA reference and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The evolution of this style

The guide below is based on APA style 7th edition, which was released in 2020. In previous versions of APA format, researchers and scholars were required to include the publisher location for books and the date that an electronic resource was accessed. Both are no longer required to be included.

Details on the differences between the 6th and 7th editions is addressed later in this guide.

Citations & References

The appearance of citations & references.

The format for references varies, but most use this general format:

%%Author’s Last name, First initial. (Date published). Title . URL

Researchers and scholars must look up the proper format for the source that they’re attempting to cite. Books have a certain format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re citing or referencing.

If you would like help citing your sources, CitationMachine.com has a citation generator that will help make the APA citation process much easier for you. To start, simply click on the source type you're citing:

• Journal articles

In-text citations

An APA in-text citation is included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an APA in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, these citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include a citation directly following it.

Citations in the text are found near a direct quote, paraphrased information, or next to a mention of another source. To see examples of some narrative/ parenthetical citations in action, look at the image above, under “All About Citations & References.”

Note: *Only include the page or paragraph number when using a direct quote or paraphrase. Page numbers have a p. before the number, pp. before the page range, and para. before the paragraph number. This information is included to help the reader locate the exact portion of text themselves. It is unnecessary to include this information when you’re simply referring to another source.

Examples of APA in-text citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (Tóibín, 2009, p. 52).

Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017, p. 12).

If including the author’s name in the sentence, place the year in the parentheses directly next to his or her name. Add the page number at the end, unless it’s a source without any pages or paragraph numbers (See Section 8.10 of the Publication manual for more details).

In-text citation APA example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, titled the “References.”

Here’s how to create in-text citations for specific amounts of authors:

APA citation with no author

When the source lacks an author’s name, place the title, year, and page number (if available) in the text. The title should be in italics if it sits alone (such as a movie, brochure, or report). If the source is part of a whole (as many web pages and articles are), place the title in quotation marks without italics (See Section 8.14 of the Publication manual ).

Structure of an APA format citation in the text narratively, with the author's name missing:

Title of Source (Year) or “Title of Source” (Year)

Structure of an APA style format citation, in parentheses at the end of the sentence, with the author’s name missing: (Title of Source, Year) or (“Title of Source,” Year)

Structure for one author

In the text, narratively: Last name of Author (Year)...(page number).

In parentheses, at the end of the sentence: (Last name of Author, Year, page number).

Structure for two authors

Place the authors in the order they appear on the source. Only use the ampersand in the parenthetical citations (see Section 8.17 of the Publication manual ). Use ‘and’ to separate the author names if they’re in the text of the sentence.

In the text, narratively: Last name of Author 1 and Last name of Author 2 (Year)....(page number).

In parentheses, at the end of the sentence: (Last name of Author 1 & Last name of Author 2, Year, page number).

Structure for three or more authors

Only include the first listed author’s name in the first and any subsequent citations. Follow it with et al.

(Last name Author 1 et al., Year, page number)

(Agbayani et al., 2020, p. 99)

Last name of Author 1 et al. (Year)...(page).

Agbayani et al. (2020)...(p. 99)

One author, multiple works, same year

What do you do when you want to cite multiple works by an author, and the sources all written in the same year?

Include the letters ‘a’ ‘b’ ‘c’ and so on after the year in the citation.

(Jackson, 2013a)

Jackson (2013a)

Writers can even lump dates together.

Example: Jackson often studied mammals while in Africa (2013a, 2013b).

On the APA reference page, include the same letters in the full references.

Groups and organizations

Write out the full name of the group or organization in the first citation and place the abbreviation next to it in brackets. If the group or organization is cited again, only include the abbreviation. If it doesn’t have an abbreviation associated with it, write out the entire organization’s name each and every time (see Section 8.21 of the Publication manual ).

First APA citation for an organization with an abbreviation: (World Health Organization [WHO], Year)

World Health Organization (WHO, Year)

Notice in the example directly above, the name of the organization is written out in full in the text of the sentence, and the abbreviation is placed in parentheses next to it.

Subsequent APA citations in the text for an organization with an abbreviation: (WHO, Year) OR WHO (Year)

All citations in the text for an organization without an abbreviation: (Citation Machine, Year) or Citation Machine (Year)

One in-text citation, multiple works

Sometimes you’ll need to cite more than one work within an in-text citation. Follow the same format (author, year) format but place semicolons between works (p. 263).

(Obama, 2016; Monroe et al., 1820; Hoover & Coolidge, 1928)

Reference list citation components

References display the full information for all the citations found in the body of a research project.

Some things to keep in mind when it comes to the references:

• All references sit together on their own page, which is usually the last page(s) of a paper.
• Title the page ‘References’
• Place ‘References’ in the center of the page and bold it. Keep the title in the same font and size as the references. Do not italicize, underline, place the title in quotation marks, or increase the font size.
• The entire page is double spaced.
• All references are listed in alphabetical order by the first word in the reference, which is usually the author’s last name. If the source lacks an author, alphabetize the source by the title (ignore A, An, or The)
• All references have a hanging indent, meaning that the second line of text is indented in half an inch. See examples throughout this guide.
• Remember, each and every citation in the text of the paper MUST have a full reference displayed in the reference list. The citations in the text provide the reader with a quick glimpse about the sources used, but the references in the reference list provide the reader with all the information needed to seek out the source themselves.

Learn more about each component of the reference citation and how to format it in the sections that follow. See an APA sample paper reference list at the end of this entire section.

Author’s names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period (see Section 9.8 of the Publication manual ).

Format: Last name, F. M.

• Angelou, M.
• Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source. You can name up to 20 authors in the reference. For sources with 2 to 20 authors, place an ampersand (&) before the final author. Use this format:

Last name, F. M., & Last name, F. M.

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., Giles, R. M., Thorpe, A., Lukes, R., Bever, D. J., & He, Y.

If there are 21 or more authors listed on a source, only include the first 19 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using a free APA citation tool, like the one at CitationMachine.com, the names of the authors will format properly for you.

###No authors

If the source lacks an author, place the title in the first position in the reference (Section 9.12 of the Publication manual ). When the source’s title begins with a number (Such as 101 Dalmatians ), place the reference alphabetically as if the number was spelled out. 101 Dalmatians would be placed in the spot where ‘One hundred’ would go, but keep the numbers in their place.

Additionally, if the title begins with the words ‘A’, ‘An,’ or ‘The,’ ignore these words and place the title alphabetically according to the next word.

See the “Titles” section below for more information on formatting the title of sources.

###Corporate/Organization authors

On an APA reference page, corporate authors are always written out in full. In the text of your paper, you may have some abbreviations (such as UN for United Nations), but in the full references, always include the full names of the corporation or organization (following Section 9.11 of the official Publication manual ).

%%United Nations. (2019). Libya: $202 million needed to bring life-saving aid to half a million people hit by humanitarian crisis. https://news.un.org/en/story/2019/02/1031981

Publication date & retrieval date

Directly after the author’s name is the date the source was published. Include the full date for newspapers and magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

%% Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer . http://www.philly.com/

If using our APA Citation Machine, our citation generator will add the correct format for you automatically.

Giving a retrieval date is not needed unless the online content is likely to be frequently updated and changed (e.g., encyclopedia article, dictionary entry, Twitter profile, etc.).

%%Citation Machine [@CiteMachine]. (n.d.). Tweets [Twitter profile]. Twitter. Retrieved October 10, 2019, from https://twitter.com/CiteMachine

When writing out titles for books, articles, chapters, or other non-periodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized. For books and reports, italicize the title in the APA citation.

Strange case of Dr. Jekyll and Mr. Hyde.

Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks in the reference list. Here’s a good general rule: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone. Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

The Citation Machine citation generator will format the title in your citations automatically.

Additional information about the title

If you feel it would be helpful to include additional information about the source type, include a descriptive noun or two in brackets immediately following the title. Capitalize the first letter.

%%Kennedy, K., & Molen, G. R. (Producers), & Spielberg, S. (Director). (1993). Jurassic Park [Film]. USA: Universal.

Besides [Film], other common notations include:

• [Audio podcast]
• [Letter to the editor]
• [Television series episode]
• [Facebook page]
• [Blog post]
• [Lecture notes]
• [PowerPoint presentation]
• [Video file]

If you are using Citation Machine citing tools, additional information about the title is automatically added for you.

Publisher information

For books and reports, include the publisher name but not the location (see Section 9.29 of the Publication manual ). Older editions of the style required the city, state and/or country, but this hasn't been the case since the 7th edition was released.

It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the reference. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized. There is no space after the closing parenthesis and before the volume number.

%%Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016). A study on the role of computers in adult education. Educational Research and Reviews , 11 (9), 907-923. https://doi.org/10.5897/ERR2016.2688

After including the publisher information, end this section with a period.

Perseus Books.

Electronic source information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of an APA citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL (see Section 9.34 in the Publication manual ).

For DOIs, include the number in this format:

http://doi.org/xxxx

For URLs, type them in this format:

http:// or https://

Other information about electronic sources:

• If the URL is longer than a line, break it up before a punctuation mark.
• Do not place a period at the end of the citation/URL.
• It is unnecessary to include retrieval dates, unless the source changes often over time (like in a Wikipedia article).
• It is not necessary to include the names of databases

If using the Citation Machine APA citation website autocite features, the online publication information will be automatically replaced by the DOI. The Citation Machine APA template will properly cite your online sources for you.

Make sure you run your completed paper through the Citation Machine Plus smart proofreader, which scans for grammar, spelling, and plagiarism. Whether it’s an adjective , verb , or pronoun out-of-place, our technology helps edits your paper for you!

Annotated bibliographies:

An APA annotated bibliography is a full bibliography that includes a small note for each reference citation. Each note should be short (1-2 paragraphs) and contain a summary or your evaluation about each source. When creating your citations on CitationMachine.net, there is a field at the bottom of each form to add your own annotations.

Follow the publication manual guidelines on paper format and writing style. Let your instructor guide other details about your annotations. Still confused? Read our guide on annotated bibliographies .

These types of projects look different depending on the style you’re using. Use the link at the top of the page to access resources related to the Modern Language Association’s style. Here’s information related to Chicago citation style .

Page formatting

Need help with the design and formatting of your paper? Look no further! This section provides the ins and outs of properly displaying the information in your APA essay.

• Times New Roman, 12-point size.
• Calibri, Arial, or Georgia, 11-point size
• Lucida, Sans Unicode, or Computer Modern, 10-point size
• Indents = Every paragraph should start with an indent.
• Margins = 1 inch around the entire document
• Spacing = Double space everything!

Arrange your pages in this order:

• Page 1 - APA Title Page (see below for information on the title page)
• Page 2 - Abstract (If your professor requests one)
• Page 3 - First page of text
• References begin on their own page. Include the list of references on the page after the text.
• Tables and figures

Keep in mind that the order above is the recommendation for papers being submitted for peer review. If you’re writing an APA style paper for a class, your professor may be more lenient about the requirements. Also, if you’re submitting your paper for a specific journal, check the requirements on the journal’s website. Each journal has different rules and procedures.

Just a little nudge to remind you about the Citation Machine Plus smart proofreader. Whether it’s a conjunction or interjection out of place, a misspelled word, or an out of place citation, we’ll offer suggestions for improvement! Don’t forget to check out our APA citation maker while you’re at it!

Running heads

In older editions of APA, running heads were required for all papers. Since the 7th edition, that’s changed.

• Student paper: No running head
• Professional paper: Include a running head

The running head displays the title of the paper and the page number on all pages of the paper. This header is found on every page of a professional paper (not a student paper), even on the title page (sometimes called an APA cover page) and reference list (taken from Section 2.8 of the Publication manual ).

It's displayed all in capital letters at the top of the page. Across from the running head, along the right margin, is the page number.

• Use the header feature in your word processor. Both Google Docs and Word have these features available.
• Use one for the recommended fonts mentioned under "Page formatting."

Title pages

A title page, sometimes called an APA cover page, graces the cover of an essay or paper. An APA title page should follow rules from Section 2.3 of the official Publication manual and include:

• Page number, which is page 1
• Use title case and bold font
• The title should be under 12 words in length
• The title should be a direct explanation of the focus of the paper. Do not include any unnecessary descriptors such as “An Analysis of…” or “A Study of…”
• Exclude any labels such as Mr., Ms., Dr, PhD...
• Name of the school or institution
• Course number and/or class name
• Name of your instructor, including their preferred honorifics (e.g., PhD, Dr., etc.)
• Paper’s due date
• If this is a professional paper, also include a running head. If this is a student paper, do not include one.

Follow the directions for the running head and page number in the section above. Below the running head, a few lines beneath, and centered in the middle of the page, should be the title. The next line below is the author’s name(s), followed by the name of the school or institution, the class or course name, your instructor’s name, and the paper’s due date.

All components on this page should be written in the same font and size as the rest of your paper. Double space the title, names, name of school or institution, and all other information on the page (except for the running head and page number).

Example - Student Title Page APA:

Example - Professional Title Page APA:

If you’re submitting your paper to a journal for publication, check the journal’s website for exact requirements. Each journal is different and some may request a different type of APA format cover page.

An abstract briefly but thoroughly summarizes dissertation contents. It’s found in the beginning of a professional paper, right after the title page. Abstracts are meant to help readers determine whether to continue reading the entire document. With that in mind, try to craft the lead sentence to entice the reader to continue reading.

Here are a few tips:

• Be factual and keep your opinions out. An abstract should accurately reflect the paper or dissertation and should not involve information or commentary not in the thesis.
• Communicate your main thesis. What was the examined problem or hypothesis? A reader should know this from reading your abstract.
• Keep it brief. Stick to the main points and don’t add unnecessary words or facts. It should not exceed 250 words.
• Consider your paper’s purpose. It’s important to cater your abstract to your paper type and think about what information the target audience for that paper type would want. For example, an empirical article may mention methodology or participant description. A quantitative or qualitative meta-analysis would mention the different variables considered and how information was synthesized.
• Use verbs over noun equivalents, and active voice. Example: “There was research into…” becomes “We researched…”

Formatting guidelines:

• The abstract goes after the title page.
• It should have the same font (size and type) as the rest of the paper.
• It should stick to one page.
• Double-space all page text.
• Center and bold the word “Abstract” at the top of the paper.
• Don’t indent the first line of the abstract body. The body should also be in plain text.
• For the keywords, place it on the line after the abstract and indent the first line (but not subsequent lines). The word “Keywords:” is capitalized, italicized, and followed by a colon. The actual keywords are sentence case and in plan font.
• List each keyword one after the other, and separate them by a comma.
• After the last keyword, no ending punctuation is needed.

Tables & Figures

If your paper includes a lot of numerical information or data, you may want to consider placing it into a table or a figure, rather than typing it all out. A visual figure or simple, organized table filled with numerical data is often easier for readers to digest and comprehend than tons of paragraphs filled with numbers. Chapter 7 of the Publication manual outlines formatting for tables and figures. Let's cover the basics below.

If you’d like to include a table or figure in your paper, here are a few key pieces of information to keep in mind:

• At the end of the paper after the APA reference page
• In the text after it is first mentioned
• The table first mentioned in the text should be titled ‘Table 1.’ The next table mentioned in the text is ‘Table 2,’ and so on. For figures, it would be 'Figure 1,' 'Figure 2,' and so forth.

• Even though every table and figure is numbered, also create a title for each that describes the information it contains. Capitalize all important words in the title.
• For tables, do not use any vertical lines, only use horizontal to break up information and headings.
• Single spacing is acceptable to use in tables and figures. If you prefer double spacing your information, that is okay too.
• Do not include extra information or “fluff.” Keep it simple!
• Do not include the same exact information in the paper. Only include the complete information in one area—the table or the text.
• All tables and figures must be referenced in the text. It is unacceptable to throw a table or figure into the back of the paper without first providing a brief summary or explanation of its relevance.

Publication Manual 6th Edition vs 7th Edition

The 6th edition of the Publication Manual of the American Psychological Association was released in 2009. The current 7th edition came out in the fall of 2019 and was designed to be more student focused, provide more guidance on accessibility, and address changes that have developed over the last 10 years.

Below, we’ve listed what we feel are the most relevant changes related to APA format.

Journals and DOIs

DOI stands for “digital object identifier.” Many journal articles use and have a unique DOI that should be included in a full citation.

When including a DOI in a citation, format it as a URL. Do not label it “DOI.” Articles without DOIs from databases are treated as print works. For example:

6th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. doi: 10.1038/s41586-019-1789-8

7th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. https://doi.org/10.1038/s41586-019-1789-8

Citing Books

There are few new guidelines when you are citing a book. First, the publisher location no longer needs to be indicated.

%%Zack, P. O. (2001). The shoals of time. Bloomington, IN: First Books Library.

%%Zack, P. O. (2001). The shoals of time. First Books Library.

Second, the format of an ebook (e.g., Kindle, etc.) no longer needs to be indicated.

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic [Kindle].

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic .

Lastly, books from research databases without DOIs are treated the same as print works.

When using a URL in a citation, you no longer need to include the term “Retrieved from” before URLs (except with retrieval dates). The font should be blue and underlined, or black and not underlined.

6th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . Retrieved from https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

7th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

Within a full APA citation, you may spell out up to 20 author names. For two to 20 authors, include an ampersand (&) before the name of the last author. For sources with 21 or more authors, structure it as follows:

Structure: First 19 authors’ names, . . . Last author’s name.

7th edition example: Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J. K., Taylor, Z., Filmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., Garfield, . . . Trump, D.

When creating an in-text citation for a source with 3 or more authors, use “et al.” after the first author’s name. This helps abbreviate the mention.

6th Edition: (Honda, Johnson, Prosser, Rossi, 2019)

7th Edition: (Honda et al., 2019)

Tables and Figures

Instead of having different formats for tables and figures, both use one standardized format. Now both tables and figures have a number, a title, name of the table/figure, and a note at the bottom.

An e-book retrieved from an academic database that does not have a DOI (Digital Object Identifier) is referenced as though it were the print version, as above. (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).

Books with a URL or a DOI can be referenced like this:

• Author/editor (Surname, Initials)

(Year of publication)

• Title of book (in italics)
• (Edition) (if not the 1st edition)

Book Chapter

• Author of chapter/section (Surname, Initials)
• Title of chapter/section.
• ‘In:’ followed by author/editor of book, (in direct order)
• Title of book (in italics) .
• (Page reference).

Journal article (with DOI)

• Issue information (date, volume , issue no., pages) (volume in italics)

Journal article (21 or more authors)

List the first nineteen authors followed by three spaced ellipsis points (...) and then the last author's name.

Journal article (pre-publication)

“Pre-print”, “In press” and “advanced online publication” usually refer to articles that have been accepted for publication, but may not yet have been assigned to a publication volume/issue. These articles can be cited using the year of online publication and the DOI.

• Issue information (date, volume, issue no., pages) (if any available)
• Advance online publication.

arXiv is a collection facility for scientific 'e-prints'. Some of them have been published and some have not. APA recommends updating your references when you're close to finishing your assignment. If you've cited a preprint that has since been published, cite the published journal article.

In the example below, you will see that the title is in italics. This is because it hasn't yet been accepted in a journal and is, therefore, considered a stand-alone work.

Journal Article (with article numbers, not page numbers)

If the journal article has an article number instead of a page range, include the word “Article” and then the article number instead of the page range.

• Journal Title  (in italics)

Wikipedia is a free online encyclopaedia, created and edited by volunteers around the world. It is not a scholarly source, so your lecturer may not be happy for you to use it as a source in your assignments. Scholarly assignments should generally rely on peer-reviewed and other scholarly work vetted by experts in the field. However, it may be a good starting point for you in your research to find citations to original source materials that you do want to use.

Wikipedia is a constantly changing site, so cite an archived version of the page, if you can (select 'view history' and then the date of the version you used). If it doesn't have a permanent link to an archived version of the page, include a URL for the entry and the retrieval date. 

• Date of last update (year, month day)

Images, illustrations, photos (print)

If you are citing an illustration, figure, diagram or table, start with the source in which it appeared. For example, i f you are referencing an image printed in a book, you first mention the image in-text, indicating the name and creator of the image, and the book in which it can be found, along with the page details.  The reference list entry will be for the whole article or book.

In-text citation:

Reference List:

In the reference list, you list the book in which the image is found:

When you include an image or photo in your text, as well as citing the source, you will also need to include a caption and list it in a Table of Figures ( click here for more information ). Images you created yourself don't have to be cited, but should still be included in the list of figures.

Image, illustration, photo or table (online)

• Creator  (Surname, initial(s))
• [Internet handle] (if appropriate)
• Title of image, figure, illustration or table 
• [Type of image]. (image, chart, diagram, graph, illustration or photograph)

Photographs (Online Collection)

• Photographer
• Title of photograph (if applicable)

• Publisher (if different from author)
• URL (if viewed online)

It can often be hard to find accurate information about images accessed online.  However, if you do need to cite an image with no author, date or title listed, there are ways around this.  For untitled images, include a description of the image, in square brackets, where the title would usually go. If there is no publication date, add “n.d.” in place of the date, and add the date that you accessed the image.

• Curator(s) (Surname, Initial(s)) .
• (Year or years ran).

• APA Citation Generator

Free APA Citation Generator

Generate citations in APA format quickly and automatically, with MyBib!

🤔 What is an APA Citation Generator?

An APA citation generator is a software tool that will automatically format academic citations in the American Psychological Association (APA) style.

It will usually request vital details about a source -- like the authors, title, and publish date -- and will output these details with the correct punctuation and layout required by the official APA style guide.

Formatted citations created by a generator can be copied into the bibliography of an academic paper as a way to give credit to the sources referenced in the main body of the paper.

👩‍🎓 Who uses an APA Citation Generator?

College-level and post-graduate students are most likely to use an APA citation generator, because APA style is the most favored style at these learning levels. Before college, in middle and high school, MLA style is more likely to be used. In other parts of the world styles such as Harvard (UK and Australia) and DIN 1505 (Europe) are used more often.

🙌 Why should I use a Citation Generator?

Like almost every other citation style, APA style can be cryptic and hard to understand when formatting citations. Citations can take an unreasonable amount of time to format manually, and it is easy to accidentally include errors. By using a citation generator to do this work you will:

• Save a considerable amount of time
• Ensure that your citations are consistent and formatted correctly
• Be rewarded with a higher grade

In academia, bibliographies are graded on their accuracy against the official APA rulebook, so it is important for students to ensure their citations are formatted correctly. Special attention should also be given to ensure the entire document (including main body) is structured according to the APA guidelines. Our complete APA format guide has everything you need know to make sure you get it right (including examples and diagrams).

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

Our APA generator was built with a focus on simplicity and speed. To generate a formatted reference list or bibliography just follow these steps:

• Start by searching for the source you want to cite in the search box at the top of the page.
• MyBib will automatically locate all the required information. If any is missing you can add it yourself.
• Your citation will be generated correctly with the information provided and added to your bibliography.
• Repeat for each citation, then download the formatted list and append it to the end of your paper.

MyBib supports the following for APA style:

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.

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.

In the reference list , start with the author’s last name and initials, followed by the year. The book title is written in sentence case (only capitalize the first word and any proper nouns ). Include any other contributors (e.g. editors and translators) and the edition if specified (e.g. “2nd ed.”).

Are your APA in-text citations flawless?

The AI-powered APA Citation Checker points out every error, tells you exactly what’s wrong, and explains how to fix it. Say goodbye to losing marks on your assignment!

Get started!

A citation of an ebook (i.e. a book accessed on an e-reader) or a book viewed online (e.g. on Google Books or in PDF form ) includes the DOI where available. If there is no DOI, link to the page where you viewed the book, or where the ebook can be purchased or accessed.

Since ebooks sometimes do not include page numbers, APA recommends using other methods of identifying a specific passage in your in-text citations—for example, a chapter or section title, or a paragraph number.

When citing a particular chapter from a book containing texts by various authors (e.g. a collection of essays), begin the citation with the author of the chapter and mention the book’s editor(s) later in the reference. A page range identifies the chapter’s location in the book.

Some books come in multiple volumes. You may want to cite the entire book if you’ve used multiple volumes, or just a single volume if that was all you used.

Citing a single volume

When citing from one volume of a multivolume book, the format varies slightly depending on whether each volume has a title or just a number.

If the volume has a specific title, this should be written as part of the title in your reference list entry.

Eliot, T. S. (2015). The poems of T. S. Eliot: Vol. 1. Collected and uncollected poems (C. Ricks & J. McCue, Eds.). Faber & Faber.

If the volume is only numbered, not titled, the volume number is not italicized and appears in parentheses after the title.

Dylan, B. (2005). Chronicles (Vol. 1) . Simon & Schuster.

Citing a multivolume book as a whole

When citing the whole book, mention the volumes in parentheses after the title. Individual volume titles are not included even if they do exist.

Eliot, T. S. (2015). The poems of T. S. Eliot (Vols. 1–2) (C. Ricks & J. McCue, Eds.). Faber & Faber.

All the information you need to cite a book can usually be found on the title and copyright pages.

The APA reference list entry for the book above would look like this:

Butler, C. (2002). Postmodernism: A very short introduction . Oxford University Press.

When a book’s chapters are written by different authors, you should cite the specific chapter you are referring to.

When all the chapters are written by the same author (or group of authors), you should usually cite the entire book, but some styles include exceptions to this.

• In APA Style , single-author books should always be cited as a whole, even if you only quote or paraphrase from one chapter.
• In MLA Style , if a single-author book is a collection of stand-alone works (e.g. short stories ), you should cite the individual work.
• In Chicago Style , you may choose to cite a single chapter of a single-author book if you feel it is more appropriate than citing the whole book.

The abbreviation “ et al. ” (meaning “and others”) is used to shorten APA in-text citations with three or more authors . Here’s how it works:

Only include the first author’s last name, followed by “et al.”, a comma and the year of publication, for example (Taylor et al., 2018).

In the 7th edition of the APA manual, no location information is required for publishers. The 6th edition previously required you to include the city and state where the publisher was located, but this is no longer the case.

If you’re citing from an edition other than the first (e.g. a 2nd edition or revised edition), the edition appears in the reference, abbreviated in parentheses after the book’s title (e.g. 2nd ed. or Rev. ed.).
