Dave, I hate to step on your idea, but it's already been done in two different formats. The first is called BookMooch and the site can be found at http://bookmooch.com/. This is a book exchange site where you catalog the books you're willing to share. You receive points for books you send, and spend points to receive books. The _sender_ of the book pays shipping, which kind of sucks if you send out of country. They compensate by giving 3 points to the sender, and the receiver only requires 2 points to spend. It's actually a pretty cool system. The second site is called BookCrossing, the site is at http://bookcrossing.com. This book exchange site promotes the idea of tagging books (like wildlife animals) with an ID and then "releasing" the books "in the wild". You don't get points, and it doesn't cost you anything to participate. You then "hunt" for books you find off the list of those released. I almost equate it to a pseudo-acceptable way to throw your books away at local coffee shops and laundrymats. What you don't get is that direct person-to-person exchange of books. Yours would be the third type of site, which is a membership fee, free shipping paradigm. Might work. *shrug* Good luck! Chad
