In addition to the library's online catalog and databases, there are sites that are helpful in finding monologues. Here are a few.
How To Find Monologues
1. You can just search monologues in Library Search, directly from the library's home page. If you already know the play that contains the monologue that you want, then you can find the play in Temple's Library Search for Books.
2. You can ask for the monologue collection which is on permanent reserve at the Library’s Circulation Desk. (not available Fall 2020).
3. Search monologue in "Black Drama", "Black Drama Second Edition" or "Twentieth Century North American Drama".
4. Drama Online also has a monologue search. Click on "Plays" and near the upper right there is a red link "Find monologues".
