507 Scale Note for Graphic Material

Field definition and scope:

Field 507 contains the scale of a graphic material item given as a note. The field is used with architectural drawings and with three-dimensional artifacts.

For maps, this field can only be used to give scale information in records formulated according to pre-AACR 2 cataloging rules. Scale notation is given in field 255 (Cartographic Mathematical Data) in AACR 2 formulated records.

For visual materials, this field is used with architectural drawings and with three-dimensional artifacts.

The National level record requirement for this field is Optional.

Field 507 is NOT repeatable.

Guidelines for applying content designators:

For indicator and subfield code definitions and examples, National-level (NLR) and Minimal-level (MLR) record requirements, and designator repeatability, see table below:

Position	Description	NLR	MLR	Repeatability
Field 507	Scale Note for Graphic Material	O	O	NR
Indicator:
First	Undefined; contains a blank	M
Second	Undefined; contains a blank	M

Subfield code:
$a	Representative fraction of scale note	A	O	NR
$b	Remainder of scale note	A	O	NR
$6	Linkage	A	O	NR
$8	Field link and sequence number	O	O	R
