007 Field

Use field 007 to code data related to the physical characteristics of resources. The data coded in field 007 may refer to the resource as a whole, to parts of the resource including accompanying material, or to additional physical characteristics applicable to the resource. The physical characteristics are often related to information in other parts of the MARC record, including field 300, fields 33x and 34x, and some of the 5xx note fields.

Codes differ dependent on the format of the resource.
