6XX Subject Access Fields (Variable Data Field)
Definition and scope:
The 6XX fields contain subject access entries and terms. Most of these fields contain subject added entries or access terms based on the lists and authority files identified in the second indicator (Subject heading system/thesaurus) or in subfield $2 (Source of subject heading or term). One field contains uncontrolled subject access data.
For mixed materials and collections under archival control, considerable use is made of the 6XX fields to reflect the subject content of the described materials through controlled and uncontrolled headings and terms. The 7XX fields are used less frequently to provide access.
