This field contains a publisher's number which is not governed by any international standard and which is generally used for sound recordings, publications of music (printed music), videorecordings and electronic resources. The field corresponds to the ISBD standard number (or alternative) and terms of availability area. The field may contain the terms of availability and/or price, even if it does not contain a publisher's number.

Indicator 1 specifies the type of publisher's number contained in the field.
Indicator 2 specifies whether the agency supplying the record would use the data to display a note. If a generated note is not required (perhaps because the agency has also entered details in field 300 or 301) then this number should be set to "0" (see example 3) .
It is used to differentiate between publishers' numbers if the record contains more than one number.
The issue number is the number used to identify the issue designation or serial identification (see examples 1, 7) assigned by a publisher to a specific sound recording, to a side of a sound recording, to a performance on a sound recording, or to a group of sound recordings issued as a set. The issue number normally appears on the label and often on the packing for these recordings. For a set of recordings there may be issue numbers on each disc and an additional set number on the packing.
The matrix number is used to identify the master from which the specific recording was pressed, usually appearing inscribed in the wax disc. It may be used for identification of a sound recording in the absence of an issue label number.
The plate number (see examples 2, 3) is a serial number assigned by a publisher to a specific music publication. It is usually printed at the bottom of each page of music and sometimes appears also on the title page.
Other publishers number (see example 4) are numbers similar to plate numbers but not appearing on each page of the publication. They may appear on the title page, the cover and/or the first page of music.
