APA style dictates that authors are listed by last name followed by initials; publication year goes within parentheses, followed by a period. The title of an article or book title is in sentence-case, meaning only the first word and proper nouns in the title are capitalized. A periodical title is run in title case, and is followed by the volume number which, with the title, is also italicized.
Periodical (journal, magazine, newspaper) in print
Surname, F. M. (year). Title of article. Title of Periodical, Vol#(issue#), page-numbers.
*Work, S. (2022). Social workers save lives. Journal of All Good Things, 1(1), 1-20.
Articles retrieved from electronic sources
APA style prefers the inclusion of DOIs (Digital Object Identifiers) for online journal articles in reference lists. This is a unique number assigned to each published article. If there is no DOI, include the date retrieved and URL if the article is available on an open website. IF ONLY AVAILABLE THROUGH A DATABASE, do not include a URL (database URLs will not get readers to the article as they are often behind a paywall or the database URL times out).
Surname, F. M. (year). Title of article. Title of Periodical, Vol.#(issue#), page numbers. DOI
Mech, T. F., & Brooks, C. I. (1997). Anxiety and confidence in using a library by college freshmen and seniors. Psychological Reports, 81(3, Pt 1), 929–930. https://doi-org/10.2466/pr0.19184.108.40.2069
Surname, F. M. (year). Title of article. Title of Periodical, Vol.#(issue#), page numbers. Retrieved Month date, Year, from URL
Article From a library database
When referencing material obtained from an online database (such as a database in the library) that does not have a DOI, provide appropriate print citation information (formatted like a print citation would be for that type of work). This will allow people to retrieve the print version if they do not have access to the database from which you retrieved the article.
