FIELD DEFINITION AND SCOPE

Classification number assigned to documents by designated agencies in countries that have a government documents classification program.

Government agency may be at any level (e.g., provincial, state, national, international). If a number can be characterized as both a stock number (field 037) and a classification number, the number is recorded in field 086. If the nature of the number is unknown, it is recorded in field 037 (Source of Acquisition). Field 086 is repeated for multiple valid government document classification numbers.

CONTENT DESIGNATOR HISTORY

This field was defined originally as Superintendent of Documents Classification. Both indicators were undefined; subfield $a contained the classification number [USMARC only]. In 1975, the scope of the field was expanded to include document numbers from other government jurisdictions and the name changed to Government Document Number. In 1981, the scope of the field was restricted to call numbers and classification numbers.

Indicator 1 - Government jurisdiction (BK, MP, MU, VM, SE)
In 1975, the first indicator was defined as Government jurisdiction with values 0 (United States), 1 (Canada), 2-9 (Reserved). In 1981, the first indicator definition was made obsolete and subfield $2 was defined for recording a code for the source of the number. In 1985, the first indicator position was given its present definition.
Indicator 2 - Printing Agency [OBSOLETE, 1997] [CAN/MARC only]
Second indicator was defined to indicate the name of the printing agency as well as the language of the work. The values were: # (when first indicator is not “1"), 0 (IC cat. no.), 1 (Cat. IC, no.), 2 (QP cat. no.), 3 (Cat. IR, no.), 4 (DSS cat. no.), and 5 (Cat. MAS, no.).
