Every time you refer someone to PaperBackSwap and they sign up, post 9 or more books and list your email address as the person who referred them, you'll receive an extra book credit from us as a way of saying thanks! We want to build the largest virtual paperback book club in the world. The best way to do that is through positive support from our members. The Referrals work as listed below.
