desirable, such as in audiovisual production and distribution systems, broadcasting

applications, and electronic program guides. 

A V ISAN consists of the 16 hexadecimal digits of the ISAN for an audiovisual work,

followed by a version segment of 8 hexadecimal digits.  Whenever it is presented in

human readable form, the V ISAN is prefaced by the label ISAN and the appropriate check

characters are included after both the ISAN and version segments.

Example:  ISAN 1881 66C7 3420 6541 9 9F3A 0245 U

The assignment of a V ISAN does not constitute evidence of the ownership of rights to

either that version or related content or to the audiovisual work itself.

At the point of publication [Jan. 2005], the V ISAN is undergoing standardisation through

ISO TC46/SC9 Working Group 1. Subject to ISO s approval processes, the standard will

be published as ISO 15706 2.  It will be accompanied by Technical Report 20925,

consisting of informative guidelines for the operations of the V ISAN system under the

provisional title: 

Information and documentation   International Standard Audiovisual

Number (ISAN)   Version segment (V ISAN) operational guidelines

13.5 ISMN

The ISMN (International Standard Music Number) identifies all printed sheet music

publications, whether available for sale, or hire, or gratis.

It is a ten digit identifier, the first character being  M . The letter  M  distinguishes the ISMN

from the ISBN and other standards.

The other elements are: a publisher identifier that identifies a particular music publisher, a

title number that identifies a specific sheet music publication, and a check digit that is

calculated according to a modulus 10. The letter  M  counts as 3.

The ISMN can be integrated into the international 13 digit bar code, using the EAN prefix

979.  M  is assigned the numeric value of zero (0) for bar code purposes only.

The ISMN is not used for books on music, which receive an ISBN, nor is it used for music

tapes, CDs, or videos.

Items specifically assigned ISMNs include scores (both orchestral and vocal), sets of

parts, anthologies, microform, Braille and electronic music publications and song books

(optional).In some cases, a song book, a hymnal, or an album with extensive text and/or

illustrations may be considered a music edition, a  normal  book, or both. In such cases,

both an ISMN and an ISBN may be assigned, in which case both identifiers must be

printed on the publication and clearly identified.      

The ISMN is administered by the International ISMN Agency:
