Web site BookMooch is a free community designed to make it easy and cheap to exchange books with other users. BookMooch charges nothing for swapping books – you only pay for shipping. It works on a point system, in which you get points for typing in books you want to give away and sending books to other users. According to the site, as long as you send out one book for every two sent your way, you should stay afloat, point-wise.
