These databases and indices are a good place to find journal articles relating to the study of Theatre. You'll find both scholarly articles and play reviews. I recommend starting with International Bibliography of Theatre and Dance with Full Text or MLA International Bibliography first.
Print reference books related to the study of Theatre are on the ground floor of King, in the IMC.
Here are a couple of basic titles that you might find helpful:
The Cambridge Guide to American Theatre ed. by Don B. Wilmeth. PN2221.C37 2007

The Language of Theatre by Martin Harrison. PN2035.H297 1998
The Ultimate Scene and Monologue Sourcebook: An Actor's Guide to Over 1,000 Monologues and Scenes from More than 300 Contemporary Plays by Ed Hooks. PN2080.H665 2007
Click on the "Find it!" icon to find more information about where to get the actual article once you find it in an index or database.
If the article is available online, you will see a link to it.
If the article is available in print, you will see a library location (e.g. King Library) and a call number. Go to that library's periodicals section and look up the call number. Make sure you write down the volume, issue, and year of your article before you go.
If no copies are available, click on the link that says "InterLibrary Loan Options." Click on "Journal Article" and fill out the info. We will try to find the article for you and mail or email it to you.
Given the nature of your project, you will also be consulting broader historic and cultural sources. Some good encyclopedias include:
