Definition and scope:

The 700-75X fields contain index terms that supplement terms contained in data in the MARC record.  They are intended to provide subject access and links to the classification number or number span in field 153 (Classification Number).

These fields contain established subject access terms from the subject heading systems and thesauri identified in the second indicator (Subject heading system/thesaurus) or in subfield $2 (Source of heading or term) and Field 754 contains a topical subject constructed from a faceted vocabulary.  Field 753 (Index Term-Uncontrolled) contains uncontrolled index terms, which provide additional access terms, references between terms, and vocabulary control.

Fields 700-751 and 754 parallel the subject added entry fields, 600-651, and 654 in the bibliographic format.
