Bookcrossing

Go to this website: BookCrossing. The members "release" books all over the world, in cafes, on park benches, etc., for others to find and enjoy. You can also use the website to "hunt" for books that other members have released in your area. Become a member, and release some of that stuff you'll never read again, or hunt around your city for books that other members have left behind. It's a great community for those who love books, sharing, and traveling.
