FIELD DEFINITION AND SCOPE
Physical description information for an item that requires technical equipment for its
use or an item that has special conservation or storage needs.
Coded physical information is contained in field 007 (Physical Description Fixed Field).
The field is repeated for each subfield $3 (Materials specified).
