International Standard Book Number (ISBN) is a 10 or 13-digit number that’s unique to each book. You can find this next to the barcode or on the publishing page towards the front of the book. 

If your book does not have a barcode, or a sticker may be covering the barcode, then take a look inside at the title page. The title page has publisher information and copyright details. Books published before 1970 do not have ISBN assigned and we can not accept them.


We typically pay the most for textbooks but we also buy a wide variety of other books. We are currently buying over 1 Million different books - basically anything with an ISBN and in demand.
