ISBN Barcode

ISBN (International Standard Book Number) barcodes are needed for books, novels, e-books and once-off publications. Without an ISBN barcode, the book will not be accepted to be sold in retail or book stores, online stores, distribution houses, etc. Each volume, variation or edition of your book will need a unique ISBN number.
ISSN Barcode
