Content designator history:

First Indicator - Government jurisdiction (BK MP MU VM) [obsolete]

Values 0 - United States [obsolete]

1 - Canada [obsolete] [CAN/MARC only]

2 - France [obsolete] [CAN/MARC only]

Prior to 1979, field 017 was limited to U.S. copyright registration numbers. In 1979, the first indicator was defined with values 0 (United States), 1 (Canada), and 2-9 (Reserved) to include numbers from other government jurisdictions. This first indicator definition was made obsolete when subfield $b was defined in 1980 for USMARC and in 1984 for CAN/MARC.

Second Indicator - Display constant controller [redefined, 2004]

Values # - Copyright or legal deposit number

8 - No display constant generated

Prior to 2004, this indicator was undefined.

Subfield $a - Copyright or legal deposit number [renamed, 2004]: Subfield $a was renamed; formerly Copyright registration number.

Subfield $b - Source (assigning agency) [redefined, 2001]: Subfield $b was redefined as Assigning agency to differentiate it from subfield $2 (Source).

Subfield $d - Date [new, 2004]: Subfield $d was defined to record the date on which the copyright registration number was defined.

Subfield $i - Display text [new, 2004]: Subfield $i was defined to contain text to be displayed when the display constant associated with second indicator value # is inadequate.
