Before conducting your search:
The most comprehensive database for literary studies is the MLA International Bibliography, which forms part of Literary Reference Center Plus.
Begin with the database above. If you are looking for material on religion, class, gender studies, history, or visual arts, you're best bet is also to start with this database; however, you can also try one of the discipline-specific or multidisciplinary databases below.
Once you have found relevant resources, use the "Full Text Online" link to get access. If the library does not have access, request the item through Document Delivery.
