Many disciplines use MLA style, the citation style developed by the Modern Language Association. Some disciplines require other citation styles such as the Turabian, Chicago, or APA (American Psychological Association) styles.Always ask your professor which style is preferred in his or her class. There are online style guides on the library web page (http://libraryweb.utep.edu/db/citing.cfm) as well as printed style guides at the Reference Desk. A librarian will always be glad to help you, too.
