Sell or trade your books here. Now there is a alternative option.
Book Works is a simple idea from a student who is tired of pouring money into overpriced textbooks.
The purpose of the site is to allow students to buy, sell or trade their used textbooks from each other. Book Works depends fully on student participation and is absolutely free. Students submit books that they would like to sell or trade. The books are posted alphabetically by course title and are open to anyone to purchase. The price is set by the individual selling the book, but generally will be lower than the used bookstore price, yet above the resale price.
