Some electronic content is assigned a unique number called a Digital Object Identifier (DOI). If a DOI is provided for a journal article, you should include it after the page numbers of the article. Format all DOIs as follows:
https://doi.org/xxxxx
("xxxxx" = DOI number)
(Additional info on DOIs and URLs is linked at the bottom of this page.)
Author
If an item has no author, start the citation with the article title.
When an article has one to seven authors, all authors' names are cited in the References List entry. When an article has eight or more authors list the first six 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.
Titles
Italicize titles of journals, magazines and newspapers. Do not italicize 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.
Dates
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)
When you are citing two different sources that share the same author and year of publication, assign lowercase letters after the year of publication (a, b, c, etc.). Assign these letters according to which title comes first alphabetically. Use these letters in both in-text citations and the Reference list.
Example In-Text:
Paraphrasing content from first source by this author (Daristotle, 2015a). "Now I am quoting from the second source by the same author" (Daristotle, 2015b, p. 50).
Example Reference List entries:
Daristotle, J. (2015a). Title of first article. Journal title...
Daristotle, J. (2015b). Title of second article. Journal title...
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.
Author's Last Name, First Initial. Second Initial if Given. (Year of Publication). Title of article: Subtitle if any. Name of Journal, Volume Number(Issue Number), first page number-last page number. DOI

For Reference List entries, include all the same information (in the same order) as the examples above, however:
Note: In APA 7, up to 20 authors should now be included in a reference list entry. For sources with more than 20 authors, after the 19th listed author, any additional authors' names are replaced with an ellipsis (…) followed by the final listed author's name. Do not place an ampersand before the final author's name.
