A number of the books we sell are classed as Remainder Books. Sometimes book publishers print too many copies, in other cases bookstores purchased too many copies and have returned them to the publisher. Bargain Books therefore may have been handled a few times but are still in excellent condition.
These marks serve a purpose in the publishing world, dictated and added by the publishers themselves. When a book first goes to the retail channel, the balance of unsold stock is returned to the publishers for credit. At that time the publisher marks each book to signify it has previously been through the retail channel. Without that designation, publishers would not be able to distinguish the proper life-cycle of their inventory, forcing them to treat all books as new.
In a nutshell, this mark means you enjoy substantial savings off the publishers' list price for these books.
