People in my town have started erecting tiny libraries -- a little outdoor cabinet on a post, with a door and a roof -- where people can stash books they're done with. There's no expectation that the books will be returned, just passed on. Seems like a nice idea, although I've not gone near them because I'm afraid I'd take books and never leave any, book hoarder that I am.
