International Standard Music Number (ISMN)

The International Standard Music Number (ISMN) is a unique, 8- or 13-digit code assigned to printed music publications, such as sheet music, scores, and songbooks. Its purpose is to identify and catalog these items in a standardized way globally, making it easier for publishers, distributors, and libraries to manage and locate specific music editions. Similar to ISBNs for books, ISMNs help ensure accurate ordering, inventory control, and copyright management within the music industry. By providing a consistent identifier, the ISMN facilitates efficient communication and transaction of music printed materials worldwide.
