The field contains the International Standard Book Number. It is sometimes difficult to decide whether a publication is a music edition or a "normal" book, or both. In these cases both an ISMN and an ISBN may be assigned.
There are only a few periodicals of printed music, but many music publications are issued in series. Both categories should be assigned, an ISSN for the title of a continuing resource and an ISMN for each individual item in the series.
