http://www.paperbackswap.com I remember a lot of ladies back on the "secret habit" thread discussing how much they read. If you're like me you've got a ton of paperbacks around (I listed all mine, the total was 70!!). I decided to sign up today and already traded for two books I've been looking for. So far the service is free and sounds really cool. Let me know if you guys try it out or have heard anything about it.
