Description/Instructions

Field 074 contains the item number assigned by the U.S. Government Printing Office (GPO). The GPO item number is used to manage GPO's Depository Library Program. An item number may be assigned to a category of publications, a series, or an individual serial title.

The item number is assigned by GPO from the List of Classes of United States Government Publications Available for Selection by Depository Libraries.

Multiple 074 fields are used for serials that are distributed in both paper and microfiche and for serials that have been distributed under different item numbers. When a serial is distributed in paper and microfiche the 074 field representing the paper is given first. When a serial has been distributed under different item numbers, the earliest is given first.
