Sorry for not clarifying -- I meant a publisher paying the writer and putting it into stores.
As for Shaw and Williams, I couldn't give you any specific titles -- I just remember reading that they often published plays without a preference for actually getting them into the theater. I was just thinking that perhaps the same could go for a screenplay -- where you could have it distributed for it's own sake and have a literary experience reading it, which you could of course do with any Shaw or Williams play (something along the lines of screenwriting not being a dependent component of moviemaking, but rather a medium which can stand on it's own).
