You must use the APA (American Psychological Association) style when citing the sources you used for your research paper. The APA Publication Manual is available at the Dana Library Reference Desk. The Writing Center at the University of Wisconsin-Madison also has an excellent introduction to APA Documentation that will give you the basic information you need to create APA citations and reference lists.
The APA Style Guide to Electronic References is also available online from the Rutgers University Libraries.
You can also import references from IRIS and many of the electronic databases into RefWorks, a web-based bibliography and database manager. RefWorks will build your bibliography for you based on whatever style sheet you specify (MLA, Chicago, etc.). For information on setting up your (free) RefWorks account see the RefWorks FAQ.
