Ask each of your teachers which style they want you to use. If they have no preference, you can use any or follow these guidelines:
- APA: psychology, education, and other social sciences.
- MLA: literature, arts, and humanities.
- AMA: medicine, health, and biological sciences.
- Turabian: designed for college students to use with all subjects.
- Chicago: used with all subjects in the “real world” by books, magazines, newspapers, and other non-scholarly publications.
The complete hardcopy style manuals are kept on reserve in the Reference Department. These contain examples about citing a wider variety of sources than these web pages do, as well as other things you may need to know, such as margins, font size, etc.
