The short answer is that each citation style is used by different academic disciplines. At Whittier College, the citations styles used by each discipline are generally these:
APA - Psychology, Education, Social Work
MLA - Literature, Philosophy, History, Religion
ASA - Sociology
Chicago - Business, History, Fine Arts, Anthropology
However, if you're not sure, ask your professor which style they prefer. See the Citation Styles Guide at the Circulation Desk or a librarian for more information and resources, or review the online Citation Help Guide.
