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.
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.
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.).
