Frequently Asked Questions About the ISMN System

Part 2: Questions regarding the implementation of the 13-digit ISMN (as of January 2008)

Part 1: General questions

Q: Does a price change require a new ISMN?

A: No.

Q: Does a new title require a new ISMN?

A: Yes, you need a new ISMN for a new title.

Q:I am publishing a music print with a text part in a foreign language. Should it have an ISMN of the country in whose language the text is written?

A: No. It is the country where the publisher is based which determines which national agency should assign the publisher ID, not the language of the text.

Q: The composer is revising his composition which has been published by us before. Does the revised version if published require a new ISMN?

A: A (substantial) change requires a new ISMN.

Q: Does a reprint without any substantial change in text, music, format, or binding require a new ISMN?

A: No. The original number must be retained.

Q: I would like to issue a new ISMN for marketing reasons. Is this permissible?

A: No. There is no change of text, format or binding which would justify a new ISMN.

Q: I am reprinting a music score with a price change. Is a new ISMN required?

A: No. A price change does not require a new ISMN.

Q: What happens if I have used all the numbers under my publisher ID?

A: An additional publisher ID can be assigned--allowing for a larger output if necessary. This is an additional ID, and not a replacement.

Q: Is it possible to reassign ISMNs when the music prints to which they were allocated are out of print?

A: No. An ISMN identifies a given title, and its edition and binding for all time. Even if out of print it will still exist in some shops, and will certainly still exist in libraries.

Q: I am publishing a composition as a full score and in individual parts. Will one ISMN suffice or will each part need its own ISMN?

A: The rules state that in a publication consisting of scores and parts, the full score, the set of parts as a whole, and each individual part (if available separately) must be assigned their own ISMN.

Q: I am taking over another firm, which already has an ISMN prefix. All future music prints will be published under my name. Can I renumber all the other firm's titles?

A: Not until reprinted under your own imprint, carrying your own name.

Q: I am publishing a Braille music print. Are Braille music publications entitled to carry an ISMN?

A: Yes. Braille music publications can be assigned an ISMN.

 

Part 2: Questions regarding the implementation of the 13-digit ISMN
(as of January 2008)

Q: What happens to ISMNs that have already been obtained by a publisher but are not yet assigned?

A: The publisher should continue to use these until they are exhausted but must convert the number formats to the new 13-digit standard, prefixed by 979, and replace the M- by 0- (zero). E.g. ISMN M-345-24680-5 is converted to ISMN 979-0-345-24680-5.

Q: Will new ISMNs have to be assigned to products that have already been published?

A: No. Existing ISMNs should be converted from the 10-digit format to the 13-digit format (prefixed by 979) by 2008. This will apply to records for any title for which transactions may occur and should therefore include out of print titles as well as those currently in the catalogue. For barcoded notations: The ISMN and bar code on notations will not need to be changed until the publication is reprinted as the bar code already represents the EAN13 which is the same number as the new 13-digit ISMN.

Q: May publishers re-use existing 10-digit ISMNs on a new publication adding a 979 prefix?

A: No. The addition of a 979 prefix to a previously used ISMN does not make a new ISMN and for that reason must not be assigned to a new publication.

Q: Will I be able to communicate with trading partners using 10-digit ISMNs by end of 2008?

A: By 2008 the ISMN will be a 13-digit number and all mechanical systems will have to be able to accommodate its use in that form. Commercial systems may not support 10-digit ISMNs after that. In the transitional period, however, arrangements may be made between trading partners to support both formats.

Q: Will publishers have to change to 13-digit ISMNs or can they continue using the 10-digit ones?

A: Publishers will have to change all their systems to accommodate the 13-digit ISMN by end of 2008. It is essential that mechanical systems are adapted by that date to enable communication with trading partners to continue without interruption.

Q: If our company still has lots of 10-digit ISMNs, why do we need to reformat them as 13-digit ISMNs?

A: The International ISMN standard is changing. The ISMN system drives all trading in the industry internationally and the allocation of ISMN is organised on an international basis.

Q: Should both a 10-digit and a 13-digit ISMN be printed in a publication?

A: For notations published in 2008 and after only the 13-digit ISMN should be printed. However, for barcoded titles published after 1 January 2008, publishers should print the 13-digit ISMN in eye-readable form above the bar code on the back cover of their publications, retaining the correct hyphenated structure.
