The Product Code consists of a minimum of three and a maximum of eight alphanumeric characters in coded form, recorded in 930 subfield $a. Multiple Product Codes may be assigned in separate 930 fields.

The first three alphabetic characters indicate the Library product in which the bibliographic record will appear (bibliographies, indexes, catalogues, databases, etc.) or designate a specific scope or usage (such as digitization projects).

Four or five alphanumeric characters may be added to indicate the specific issue or date for recurring publications.

For annual publications, the year is entered as XXXYY (XXX followed by the 2 last digits of the year).

For quarterly publications, the issue and year are entered as QNYY (Q = "quarterly", N = the issue number of the volume (1, 2, 3 or 4), YY = the last 2 digits of the year).

For monthly publications, the month and year of the issue are entered as MMYY (MM = a 2-letter code for the month, YY = the last 2 digits of the year).

For weekly or biweekly publications, the month, week and year are entered as MMWYY (MM = a 2-letter code for the month, W = the number of the week of the month when the item will be published, YY = the last 2 digits of the year).
