FIELD DEFINITION AND SCOPE

Current stated publication frequency of either an item or an update to an item. Dates are included when the beginning date of the current frequency is not the same as the beginning date of publication.

In records having field 008 (Fixed-Length Data Elements) or field 006 (Fixed-Length Data Elements-Additional Material Characteristics) configured for seriality, field 362 information is related to coded information contained in 008/18 (006/01) (Frequency) and 008/19 (006/02) (Regularity). The date(s) of the current publication frequency is given when the beginning date of the current publication frequency is not the same as the beginning date of the publication.

When an item has ceased publication, the current frequency date is closed but remains in field 310.
