What Is an ISBN?
An ISBN—International Standard Book Number—is the unique identification number assigned to every published book. It works like a fingerprint: no two books share the same ISBN, and each format of a book (paperback, hardcover, ebook, audiobook) must have its own.
Why ISBNs Matter
An ISBN allows:
- Bookstores to order your book
- Libraries to catalog it
- Retailers to list it correctly
- Distributors to track sales
If you want your book to be taken seriously in the marketplace, an ISBN is essential.
What an ISBN Identifies
An ISBN carries important information about your book, including:
- Publisher name
- Book title
- Author name
- Format
- Edition
This metadata helps your book appear correctly in databases worldwide.
