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.
Why should I buy an ISBN?
There are many reasons to purchase an ISBN for your title, including:
- An ISBN improves the likelihood your book will be found and purchased

How many ISBNs do I need?
You will need one ISBN for each edition and format of your book. The ISBN identifies the publisher as well as the specific book title, edition and format (hardback, paperback, ePub, PDF, Mobi, Audio…). Any variation of a book would require the use of a unique ISBN to identify it properly. This allows retailers to help the customer understand exactly which version of a title they are purchasing. So, you should consider:
- How many book titles you are planning to publish
- How many formats will each title be created in
- Do you plan to publish future revised editions of these titles
- You can purchase ISBNs in advance and register your titles any time after they are obtained.
- ISBNs never expire.
Why should I buy my ISBNs from Bowker?
Bowker is the official ISBN Agency for publishers physically located in the United States and its territories (Puerto Rico, Guam, US Virgin Islands, Northern Mariana Islands, American Samoa, as well as military bases and embassies. 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.
