BookMooch - New Life for Old Books

I'd like to recommend a web site: BookMooch. It was created by John Buckman who made a load of cash before the tech bubble burst and created Bookmooch as a sort of public service. From the BookMooch about page:

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 five you receive.

BookMooch is cool, though parting with books isn't one of my natural inclinations. The list of books I have available is here.
