Unless you’re born with a silver spoon in your mouth, the expense of textbooks are a tough part of college — it’s the “second tuition” you have to pay.
Catherine Forsythe (one of my favorite bloggers) has come up with a new service that tries to help. BookGap is a listing service for books. Focused on textbooks (but usable for regular books), the service hopes to help bring the cost of textbooks down. You simply list a book you want, or a book you have available. You could rent a book, or sell a book. The service is free while it’s in beta.
