There are many different "styles" you may choose from when citing sources. Your professor will probably tell you which "style" is preferred for your class. MLA (Modern Language Association), Chicago, and APA (American Psychological Association) are the three which are used most often by students at The Claremont Colleges.
The following quick guides for citing your sources are from Diana Hacker's Research and Documentation Online.
If you need to cite legal documents or government publications, or just understand the citations you find, the following guides will help.
Recent editions of style manuals, which include more detailed information and examples, are available at the Services Desk in Honnold/Mudd Library.
