ISBN (International Standard Book Number)

The International Standard Book Number (ISBN) is a unique identifier assigned to books and other publications, making it easier for publishers, booksellers, and libraries to locate and order specific titles. An ISBN is typically a 13-digit number that provides information about the book, such as the publisher and the specific edition. Introduced in 1970, it helps avoid confusion between similar titles and ensures accurate tracking in inventory systems. Each edition or variation of a book, like a paperback or hardcover, gets its own ISBN, enhancing organization in the publishing industry.
