Databases - Theatre-specific databases that UT Libraries subscribes to can be found here. These include:
Journals - The "e-Journals by Subject" tab on the Libraries homepage will allow you to search for numerous journals within a broad subject area.
Use the Libraries One Search to search for specific article titles, authors, or subjects within a journal.
The Library of Congress uses Theater as a subject heading for "works on drama as acted on the stage. Works on facilities used to stage drama are entered under Theaters. Works on drama as a literary form are entered under Drama."
Note that databases may use similar terminology to mean different things.
American English spelling is typically "Theater" but the use of the British spelling - "Theatre" - is widespread in the US.
Be aware of these differences when developing a search strategy.
