ISBN Product Details

“ISBN” stands for “International Standard Book Number“.
The ISBN identifies a book or other book-like product (such as an audiobook) in a specific format and edition, but also the publisher. 

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.

If you are located in the United States, or a territory of the USA (Puerto Rico, Guam, US Virgin Islands, Northern Mariana Islands, America Samoa, as well as military bases and embassies), Bowker is the official registration agency of the ISBN.
