On the heels of Freecycle's success comes 2Swap, a new website dedicated to helping you pass your old books into loving hands, while receiving books of your choice for free.

Although its newness has not produced many text books, it would be a keen source for classics and modern literature, as well as providing for your guilty pleasure reading.

Simply create a free account and list some books you wouldn't mind sending out. For your first 10, you'll get three credits; that's three free books. Once you find one you want, just click "want it" and the owner will mail it to you at their expense, using a postage label you can print from the site.

In return for the postage, the owner receives a credit; in the end, you come out even, only ever having paid a dollar or two. There's nothing better than free books (well, assuming no one is giving out free beer).
