You should begin any research project by developing a bibliography of books and periodical articles dealing with your topic. The following databases are a good place to start.
Books: IUCAT, ACPL, Other Libraries
Periodicals
Databases and Indexes Social/Behavioral Science & Humanities
Search strategy: For most topics you will want to consult the hard cover (Readers' Guide, PerSI) as well as the electronic databases to develop your bibliography. However, if you are doing a "current events" paper, you will only have to consult the electronic resources.
