The APA Publication Manual is the official manual of style of the American Psychological Association. Developed to provide guidance and information for those writing and publishing, it is currently in its sixth edition.
The APA Publication Manual is used extensively by students, faculty, researchers, and professionals who write and publish in the fields of Psychology, Education, Business, Law and Justice, Journalism, Linguistics, Nursing, Medicine, although other styles are also used.
Which style guide should you use? The one your professor requires, so be sure to ask. If you plan to submit a paper for publication, be sure to confirm the correct style. Nearly all publications will identify and give some direction about how manuscripts should be submitted for publication. If not in the publication, guidance will be offered on publishers' websites, or the websites of the organization for whom the journal title is published, if relevant.
A copy of the APA Publication manual is also kept on Reserve. Ask at the Circulation Desk.
