Search also in MavScholar for "best plays" or the play title or the last name of the playwright and the word "play" to find many plays in print in our collection.
Don't forgot to look at our many productions of plays on DVD, which may also be found using MavScholar.
The best idea is to locate a play that interests you and then read through it to find a monologue that appeals to you. You can find many or our plays using this link to MavScholar that will search for plays. Click "General Collection" on the left menu under the heading "Collection" if you only want something in print.
You can also use this MavScholar search to see sources that contain monologues.
