The following information might be extremely useful for students who are willing to get back some money they have spent on their college textbooks. You probably already know that many textbooks are currently sold in a loose leaf, or “binder ready” format (which is also sometimes called a la Carte since they may be printed on demand by the publisher).
Check the access code. The ISBN may correspond to a bundle which includes a book and an access code. If you plan on selling your loose leaf book, this might be a problem. Such books are usually shrink wrapped, and access codes may be printed on one of the pages and be visible if you remove the original plastic wrap and open the book. In such cases, even if you have not used the code, it would still count as used since it is visible. If the description of the item includes such comments as “with supplementary materials” or “with access code”, then the book should be in original packaging and access code should not be visible for the item to qualify for buyback.
