College bookstores, stores specializing in rare and collectible books, a number of retail book outlets and numerous online sites buy used books. Depending on the book and its condition, prices vary at each. Some resellers, such as Amazon.com, buy books directly or offer more in trade-in value.
Book stores such as Powell's in the Portland area buy a wide variety of books online or at its local outlets. Like Amazon.com, it offers more in credit than in cash. TextbookRush, BookFinder, Amazon.com, and Barnes and Noble all buy textbooks, including trade books used in college classes.
Other sites, such as BookScouter and Cash4Books, advertise buying back textbooks but only quote prices on books either the company or any of its partners are seeking. For those wishing to sell their own books, Amazon.com and others offer marketplaces where used books are available at fixed prices or in auctions.
