A great collection of databases containing plays. Many also allow for monologue searching.
Most of our books of monologues have call numbers beginning with PN 2080 and are shelved on the 8th floor of Bobst Library. In the library's catalog, there is no specific subject heading for scene books. However, you can perform a keyword search in the catalog for the term monologues. You can also use the Play Index or one of the other databases listed below to search specifically for monologues or scenes.
