What the heck is an ISBN?
The ISBN (International Standard Book Number) is the most important identifier your book can have. ISBNs provide unique identification for books and simplify the distribution of your books throughout the global supply chain. Without an ISBN, your book will not be found in most bookstores, either online, or in a brick-and-mortar store.
