ISBN
ISBN (International Standard Book Number) is a unique identifier assigned to books and other publications to distinguish them in the global marketplace. It is a 13-digit number (formerly 10 digits before 2007) that helps publishers, retailers, and libraries easily track and catalog books. Each ISBN is specific to a particular edition, format, and language of a book, ensuring precise identification. For authors, publishers, and researchers, obtaining an ISBN is crucial for ensuring a book’s discoverability and proper citation. It streamlines the sales, distribution, and referencing process in academic and commercial publishing.
