Scripts can be found on the second floor of the Lucille Caudill Little Fine Arts Library, in the shelves where call numbers begin with "PN," "PQ," "PR," "PS" and "PT." It is fun to browse for plays in these sections of the library.
If you're looking for a specific play or playwright, you can look up the name or title in InfoKat Discovery to find an exact call number. Critical editions of plays are often located in William T. Young Library, so check locations carefully.
Play scripts and other information about plays can be found here.
