The 7th edition (2020) of the APA Manual is the most current edition in use.
Only one space should be used after a period (p. 154).
For the first in-text citation with 3 or more authors, you can list just the first author followed by "et al." (p. 266).
References may include up to 20 names of authors for a single work (p. 286).
Book references should no longer include publisher location (p. 295).
APA style requires the use of DOIs (Digital Object Identifiers) for all resources that have one, regardless of whether the work was found and used online or in print (p. 299).
DOIs and URLs should be presented as hyperlinks, and "doi:" and "Retrieved from" are unnecessary prior to a DOI or URL (p. 299).
DOIs should be presented in the following format: https://doi.org/xxxxx with no period at the end. If a source utilizes a different format (e.g. http://dx.doi.org/) change it to the preferred format above. It serves as a direct link to the material and provides consistency throughout the reference list. Long DOIs and URLs can be shortened using an online service (e.g. shortDOI or tinyurl) (pp. 299-300).
The 7th edition provides many more examples of citations and references for online sources. Examples of parenthetical and narrative citations are included with each reference example (See Chapter 10).
This edition provides greater instruction on how to cite digital media, with a section dedicated to Audiovisual Media (e.g. Film, TV series, Podcasts, Photographs etc.) (pp. 341-347) and another section covering many different types of Online Media (Twitter, Facebook, websites, online forums, etc.) (pp. 348-352).
Table 9.1 provides a useful guide on how to correctly format a reference even when important information may be missing (p. 284).
Here are some resources to provide you with the basics of how to use APA Style to correctly organize and attribute credit in your academic papers.
The Introduction video was uploaded October 29th, 2019 by the CSUDH Library.
In addition to the official APA manual and the examples to the right, several institutions have created helpful online guides.
* Be aware! The 7th Edition is still quite new. Some sites may not have updated their guides from the 6th Edition, so always check what edition is being referenced before using their examples! *
APA style of citing requires the use of DOIs (Digital Object Identifiers) for all resources that have one regardless of whether the work was found and used online or in print. Many databases will provide the DOI for you along with the rest of an article's citation information (title, author, etc.). However, if you cannot find a DOI for your article, or if you have a DOI, but don't know what article it is for, use the following online DOI Resolver: www.crossref.org. If you are unable to determine the DOI of a work online, you may provide the URL address of the website at the end of the citation. "Retrieved/Accessed from" is no longer used. If the work without a DOI is from an academic database, do not include the URL. Instead leave the reference as you would for the print version.
DOIs were first introduced in 2010. Most articles published before 2010 will not have DOIs assigned to them. However, some publishers are starting to assign DOIs to older articles. You should check CrossRef.org to ensure you have the most accurate information.
Author, A. A., & Author, B. B. (Year). Title of the book. Publisher Name. https://doi.org/xxxx
List author's last names in order of appearance on the book cover or title page. Only list the authors initials for first and middle names.
Use a comma to separate each author's name. Even if there are only two authors, include a comma before the "&".
Use only an "&", no comma, to separate two group authors.
For suffixes, use a comma to separate initials and the suffix (e.g. Author, A. A., Sr., & Author, B.).
All words in the book title are lowercase except for the first word of the sentence, the first word after a colon, and proper nouns (see pp. 165-169 for more on capitalization).
Include only the publisher name, not the location. Do not include business structure designations (e.g. Inc., LLC).
Always include the DOI if one is available. Double check using CrossRef.org.
The second and subsequent lines are indented, or "hanging" indentation (see pp. 321-328 for more details on citing various types of books)..

Author, A. A., Author, B. B., & Author, C. C. (year). Title of the article. Title of the Periodical, xx, pp-
List author's last names in order of appearance on the article. Only list the authors initials for first and middle names.
Use a comma to separate each author's name. Even if there are only two authors, include a comma before the "&".
With articles that contain 21 or more authors, include the first 19 names, insert an ellipsis "..." instead of the "&", and then add the final author's name. Do not use et. al in the reference list, but do use it in the in-text citation (see Chapter 10, Example 4).
All words in the title of the article are lowercase except for proper nouns and the first word of the sentence and the first word after a colon.
The title of the periodical and the volume should be in italics and written in title case. If an issue number is available, add it after the volume and in parenthesis. The issue number is not in italics.
The second and subsequent lines are indented, or "hanging" indentation. Present DOIs and URLs as hyperlinks - do not break them to make them fit neatly on the page with hanging indentation (as we did in some of these examples). Consider using an online tool (such as shortDOIs or tinyurl) to shorten lengthy hyperlinks.

Audiovisual media should be cited as you would cite other types of work with the author, date, title, and source.
Consider if the work stands alone (e.g. film, artwork, music album) or if it is one part of a bigger whole (e.g. episode in a TV series, song from a music album, picture in a book).
In-text citations follow the same pattern of author name and year (e.g. Roberts, 2019).
After the name of the creator(s), you may need to include a description of who they are in relation to the material (e.g. Spielberg, S. (Director), Thompson, C. (Writer)). In the case of a work of art or painting, you do not need to include the word 'artist' or 'painter'.
After the title of the piece, include in brackets a description of the material (e.g. [Film], [TV series], [Audiobook], [Painting], [Digital image], etc).
Present URLs as hyperlinks - do not break them to make them fit neatly on the page with hanging indentation. Consider using an online tool such as tinyurl.com to shorten a lengthy URL..
For the most part, Fair Use guidelines allow you to lawfully cite materials that are strictly for classwork. But if you wish to reproduce audiovisual work, you may need to seek permission from the copyright owner and/or provide copyright attribution according to image/audio license terms (see Section 12.15 of the APA Manual for further details)..
