Some FAQs on ISBNs
What is an ISBN?
The International Standard Book Number (ISBN) is a 13-digit number that uniquely identifies books and book-like products published internationally.
What is the purpose of an ISBN?
The purpose of the ISBN is to establish and identify one title or edition of a title from one specific publisher and is unique to that edition, allowing for more efficient marketing of products by booksellers, libraries, universities, wholesalers and distributors.
Who is eligible for an ISBN?
The ISBN Agency assigns ISBNs at the direct request of publishers, e-book publishers, audio cassette and video producers, software producers and museums and associations with publishing programs.
Where is it used and printed?
An ISBN is assigned to each title or product, including any backlist or forthcoming titles. Each format or binding must have a separate ISBN (i.e. hardcover, paperbound, VHS video, laserdisc, e-book format, etc). A new ISBN is required for a revised edition and cannot be reused. The ISBN is printed on the lower portion of the back cover of a book above the bar code and on the copyright page.
