ISBN

ISBN (International Standard Book Number) is a unique identifier for books and book-like products. It is used to identify and track publications, including books, e-books, and audiovisual materials. The ISBN code typically consists of 13 digits (since 2007) or 10 digits (prior to 2007), separated by hyphens or spaces. Each ISBN code represents a specific edition and format of a book, allowing for accurate identification and cataloging. It is commonly used by libraries, booksellers, and publishers to manage inventory and sales records.
