The International Standard Book Number (ISBN) is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation (except reprintings) of a book. For example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN.
ISBN stands for International Standard Book Number and must be unique for each title and format. Depending on the marketplace, the cost for a single ISBN can range from $29 to $129. An ISBN for an ebook only costs $29 each. Self-publisher can obtain ISBN and barcode starting at $55. For a complete rundown of pricing, please click here.
