If you're not sure where to start, here are some book available at the Central Library.
1. Dada: performance, poetry, and art by John D. Erickson
2. Ombres et soleil/Shadows and Sun, writings of Paul Eluard
3. Geography and Plays by Gertrude Stein
4. At the roots of the stars: short plays of Djuna Barnes
(note: I didn't real all but did look through and didn't find what
had been promoted as "dada plays")
