Q: What is an ISBN?


ISBN stands for "International Standard Book Number" and is a unique number that identifies a book so that authors may sell their work. Older books are identified by a 10-digit ISBN, and books published since 2007 have a 13-digit ISBN. ISBNs are issued by Bowker, the official ISBN agency in the United States.

You can find the ISBN for the books in our catalog under the Details tab. ISBNs are in the "Identifier" section:

ISBNs make it easy to find books in libraries or bookstores. To search for books in the library catalog by ISBN number, simply enter the ISBN in the search box. Make sure to enter the ISBN without any dashes or spaces:

An ISSN is a related number. ISSN stands for "International Standard Serial Number" and is a unique 8-digit code that identifies periodicals and journals.
