There weren't any books in Arena, sadly.

And no, they were both in Morrowind, because there is a quest in the game involving finding work for an out-of-work actor who is hanging around outside a shop in one of the Vivec City cantons. (You go speak to Crassius Curio, and that is the play that he wants to commission).
