The Philip Barry Papers document Barry's development and career as a playwright, from his earliest production at Yale in 1919 to his final work in 1949. The Papers are composed chiefly of Barry's notes, sketches, and drafts of his plays, materials relating to the production and publication of his plays, and correspondence with friends, family, fans, and colleagues in the worlds of theater and literature. Additional materials are also present, including scripts of plays by other authors, college and workshop notes, press clippings, and pamphlets and photographs relating to professional and social organizations.
