ISBNs help books get discovered!

An ISBN ensures your book's information will be stored in the Books in Print database which is consulted by publishers, retailers and libraries around the world.

The ISBN is a unique identifier for a book or other book-like product (such as an audiobook) that specifies its format, edition, and publisher. There are many reasons to purchase an ISBN for your title, including:

  • An ISBN improves the likelihood your book will be found and purchased
  • An ISBN links to essential information about your book
  • An ISBN enables more efficient marketing and distribution of your title
  • Most retailers require ISBNs
  • An ISBN helps you collect and analyze book sales data
  • An ISBN ensures your book’s information will be stored in the Books In Print database
  • Books In Print is consulted by publishers, retailers and libraries around world when searching for title information

Thorpe-Bowker is the official ISBN Agency for publishers physically located in Australia. If an ISBN is obtained from a source other than the official ISBN Agency, it might not identify the publisher of the title accurately. This can have implications for doing business in the publishing industry supply chain.

Once you set up your account with us, your ISBNs will be added to your account immediately at purchase (Title Assignment Instructions). You will be recognized as the publisher of all book titles associated with those ISBNs. For more information about the ISBN standard, or if you are looking for the official ISBN Agency in your jurisdiction, visit the International ISBN Agency.

NEW PUBLISHERS: A new publisher setup fee of $55 will be added to your cart if you have not previously purchased ISBNs from Thorpe- Bowker. This covers the set up of your New Publisher account, including verifying details and linking your publisher details to all the appropriate Bowker products for maximum exposure.
