Plays are Books too, Right?

We have been considering for a very long time to start including plays as a part of our website. We've decided that yes, plays can be apart of this website. No plays are not books, but they do have characters, plot, theme, setting, and everything else books have. The only difference between a play and a book is that, Plays aren't meant to be just read they are also meant to be performed. While books are made to be read.
