Style Manuals and Citation Formats
A style manual is a guide to preparing a research paper in a particular field of study. Scholarly papers frequently cite the work of other researchers in the field, so a standardized format for citing references is an important part of a style manual. It is important that each citation in this list give enough information about the reference in question, so that a reader of the paper can readily find it.
Instructors will usually indicate which citation style they would like followed for a given paper or assignment. Computer-based tools can assist in this process. One is an online program called RefWorks (available to SDSU students, faculty, and staff.) Another is a software program called EndNote, which is sold at the Bookstore.
