International Standard Music Number

EAN-13-ISMN-13

International Standard Music Number (ISMN) is a unique identifier for musical scores standardized by the International Organization for Standardization (ISO). The ISMN system was developed to simplify the distribution and cataloging of notated music and is analogous to the International Standard Book Number (ISBN) used for books. The ISMN is a thirteen-digit code that facilitates the identification of scores, individual parts, and other music-related documents published worldwide.

Overview

The ISMN system was officially adopted as an international standard in 1993 as ISO 10957. It was designed to address the need for a standardized system similar to the ISBN for the music publishing industry. The ISMN makes it easier for publishers, libraries, retailers, and collectors to identify, manage, and track music scores.

An ISMN consists of four parts:

1. The prefix "M", which distinguishes the ISMN from other standard identifiers like the ISBN.
2. A three-digit identifier that represents the country, geographical region, or language area of the publisher.
3. A variable length (up to five digits) publisher identifier.
4. A single check digit, calculated using a Modulus 11 algorithm, to validate the number.

Application and Use

Publishers of notated music apply for an ISMN for each new score or edition they publish. This includes any form of music notation, such as scores, miniature scores, and sheet music, whether available for sale, hire, or electronic distribution. The ISMN is typically printed on the score, often on the bottom right corner of the first page and on the copyright page, along with other copyright information.

The ISMN makes it easier for libraries and retailers to catalog music scores, streamlines the ordering and distribution process, and assists in copyright tracking and management. For researchers and collectors, the ISMN serves as a valuable tool for locating specific editions of scores.

Global Adoption

Since its introduction, the ISMN has been adopted by numerous countries around the world. National agencies, designated by the ISMN International Agency, are responsible for administering the system within their territories. These agencies assign publisher identifiers, distribute ISMN labels, and maintain national databases of music published in their regions.

Challenges and Limitations

While the ISMN system has significantly improved the cataloging and distribution of music scores, it faces challenges similar to those encountered by the ISBN system. These include issues with the management of digital publications and the need for more comprehensive international coverage. Additionally, the transition to digital music distribution poses questions about the role and implementation of ISMN in electronic formats.

Future Directions

The ISMN system continues to evolve in response to changes in music publishing and distribution. Efforts are underway to enhance the system's flexibility and to better accommodate digital and online music scores. The ISMN International Agency works closely with publishers, libraries, and national agencies to ensure that the system meets the industry's changing needs.
