[[Image:EAN-13-ISMN-13.png|thumb|300px|A 13-digit ISMN, 979-0-2600-0043-8, as represented by an [[European Article Number|EAN-13 bar code]].]]
The '''International Standard Music Number''' or '''ISMN''' ('''ISO 10957''') is a thirteen-character alphanumeric [[identifier]] for [[printed music]] developed by [[International Organization for Standardization|ISO]].

==Overview==
The original proposal for an ISMN was made by the UK Branch of [[International Association of Music Libraries, Archives and Documentation Centres|IAML (International Association of Music Libraries, Archives and Documentation Centres)]], put forward by Alan Pope (Blackwell's Music Department, Oxford), Malcolm Lewis (music librarian in Nottingham) and Malcolm Jones (music librarian in Birmingham). A draft ISMN structure and application was presented at the 1987 IAML conference in Amsterdam, then after further discussions at the 1989 IAML conference in Oxford it was decided that the UK, French and German branches should, through their respective national standards bodies (BSI, AFNOR and DIN) file ISMN as an ISO work project. After meetings in Ottawa and Paris in 1993 the draft was finalized and published by ISO.<ref>{{cite web | publisher = ISMN International | title = Newsletter | number = 10 | others = IAML | url = http://www.ismn-international.org/publications/newsletter10/iaml.html | access-date = 2009-06-12 | archive-url = https://web.archive.org/web/20160303174954/http://www.ismn-international.org/publications/newsletter10/iaml.html | archive-date = 2016-03-03 | url-status = dead }}</ref>

The original format comprised four elements: a distinguishing prefix M, a publisher ID, an item ID, and a check digit, typically looking like M-2306-7118-7. From 1 January 2008 the ISMN was defined as a thirteen digit identifier beginning 979-0 where the zero replaced M in the old-style number. The resulting number is identical with its [[European Article Number|EAN-13]] number as encoded in the item's barcode.<ref>{{cite web | publisher = ISMN International | url = http://www.ismn-international.org/whatis.html | title = What is | access-date = 2009-06-12 | archive-url = https://web.archive.org/web/20170520141136/http://www.ismn-international.org/whatis.html | archive-date = 2017-05-20 | url-status = dead }}</ref> The 979 [[Unique Country Code]] prefix is known as "[[Bookland|Musicland]]".<ref>{{cite web | publisher = ISMN International | title = Guidelines for the Implementation of 13-Digit ISMNs | year = 2007 | url = http://ismn-international.org/download/GuidelinesGeneral.pdf | archive-url = https://web.archive.org/web/20170821035240/http://ismn-international.org/download/GuidelinesGeneral.pdf | archive-date = August 21, 2017 | url-status=dead}}</ref>

The current format comprises four blocks: the prefix ''979-0'' reserved for ISMNs — at some future date they are expected to occupy the remainder of the 979 space which is shared with [[ISBN]]s, a block to identify the publisher, another to identify the item and one final check digit. The [[TC 46/SC 9]] is responsible for the standard.

A publication may be assigned both an ISBN and an ISMN. Unlike the ISBN, the ISMN does not segregate publishers by country.

==Check digit==
To calculate the check digit, each digit of the ISMN is multiplied by a weight, alternating 1 and 3 left to right. These weighted digits are added together. The check digit is the integer between 0 and 9 that makes the sum a multiple of 10.

===Examples===
For instance, for the item with ISMN beginning 979-0-060-11561:
: 1×9 + 3×7 + 1×9 + 3×0 + 1×0 + 3×6 + 1×0 + 3×1 + 1×1 + 3×5 + 1×6 + 3×1
: = 9 + 21 + 9 + 0 + 0 + 18 + 0 + 3 + 1 + 15 + 6 + 3
: = 85
As 85 mod 10 = 5, the check digit is 10 - 5 = 5 and the full number is 979-0-060-11561-5.

For another example, [[Robert Fripp]]'s collection of [[Guitar Craft]] scores has the ISMN 979-0-9016791-7-7.<ref>{{cite book|last=Fripp|first=Robert|author-link=Robert Fripp|title=Seven Guitar Craft themes: Definitive scores for guitar ensemble|publisher=Partitas Music|year=2011|editor-first=Horacio|editor-last=Pozzo|url=http://partitasmusic.com/ |ismn=979-0-9016791-7-7 |id=[[Discipline Global Mobile|DGM]] [[Stock-keeping unit|Sku]] partitas001 | edition=First limited |others="Original transcriptions by Curt Golden", "Layout scores and tablatures: Ariel Rzezak and Theo Morresi"}}
</ref> Given first 12 digits 979-0-9016791-7, the ISMN algorithm evaluates
: 1×9 + 3×7 + 1×9 + 3×0 + 1×9 + 3×0 + 1×1 + 3×1 + 1×6 + 3×7 + 1×9 + 3×1
: = 9 + 21 + 9 + 0 + 9 + 0 + 1 + 3 + 6 + 21 + 9 + 3
: = 123
which implies that the check digit is indeed 7 (because 123+7=130=13×10).
