I wish you would have posted this a couple weeks before you did, because I just took a bunch of Italian books to the used bookstore before moving! For books to learn Italian, just search and see what appeals to you. You'll find a lot of different language-learning books here if you search for "Italian language." For books in Italian (novels, etc.), there is this list of books that are currently posted: http://www.paperbackswap.com/Italian-Books/list/2937/ I'm sure there are more, but that would be a place to start.
