Many of you will have a journal article from a peer-reviewed source. These are quite simple to cite in APA. I am only going to show that scenario specifically as there are many dozens of other types of sources, which you can use the below resources to help you find the solution. Note the punctuations and italics.
The second example does not have an issue number, just a volume number. It also has a DOI. Always include a doi if it is available.
Last Name, First/middle initial (year). Title of the article you want to cite. Title of the Journal the Article is in. Volume:issue (pages). DOI: 1234/567.90

APA stands for the American Psychological Association. This is the citation style used most often by people writing for the social sciences, such as psychology, sociology, education, and other fields.
The sites listed below have examples of different types of citations for different types of sources (journal articles, books, chapters in books, and more). Note that the below guides are all using the 6th Edition of the APA Style. We are actively working on providing new guidance related to the 7th Edition and this page/box will change as that information becomes available.
