You will be using MLA (Modern Language Association) style when citing the sources that you use in your research papers. The MLA Style Manual is available at the Dana Library Reference Desk. The Writing Center at the University of Wisconsin-Madison also has a nice introduction to MLA Documentation that will give you the basic information you need to create MLA citations and a Works Cited list.
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.
