International Standard Book Number

An International Standard Book Number (ISBN) is a unique, 13-digit code assigned to each published book, serving as a universal identifier. It helps publishers, booksellers, libraries, and readers accurately locate, order, and manage specific book titles. The code encodes information about the publisher, edition, and format, ensuring efficient cataloging and inventory control. ISBNs simplify the process of tracking and purchasing books worldwide, reducing confusion between similar titles and editions. They are typically found on the back cover or inside the book and are essential for the book industry’s logistics and distribution systems.
