About a year ago, I joined Book Mooch, a site dedicated to sharing books. Since I started,I’ve given away 54 books and I’ve received 14. I have a great feedback rating (+52) and its really a great community of people. If you’re sitting on a ton of books, and you’d really like some new ones, this is the place for you.
BookMooch is a community for exchanging used books.
BookMooch lets you give away books you no longer need in exchange for books you really want.
Give & receive: Every time you give someone a book, you earn a point and can get any book you want from anyone else at BookMooch. Once you’ve read a book, you can keep it forever or put it back into BookMooch for someone else, as you wish. No cost: there is no cost to join or use this web site: your only cost is mailing your books to others. Points for entering books: you receive a tenth-of-a-point for every book you type into our system, and one point each time you give a book away. In order to keep receiving books, you need to give away at least one book for every three you receive.
