If you are one of those people that loves to read paperback books, here is a site that might be of interest to you. The paperbackswap.com site lets you swap your paper back books for different paper back books. I have some friends that have stacks and stacks of paper back books and don't know what to do with them. The site is free (right now) and the only cost to you is the postage to mail the book to the person that wants it. Check it out!
