MARC 21 Concise Classification: Index Term Fields (70X-75X)

This is an ARCHIVED VERSION of the 2000 electronic edition of the MARC 21 Concise Formats. Please see www.loc.gov/marc/concise/ for the most up-to-date version of the electronic MARC 21 Concise Formats.

Fields 700-751 and 754 contain controlled subject access terms that provide subject access and links to the classification number or number span in field 153 (Classification Number). These fields are patterned after the 600-651 and 654 subject added entry fields in the MARC 21 Format for Bibliographic Data and, except for the absence of bibliographic subfields $u (Affiliation), $4 (Relator code) and $6 (Linkage), the defined indicators and subfield codes are the same as those listed in the MARC 21 Concise Format for Bibliographic Data. Definitions for the additional subfields defined for some of these fields in classification data records are given this section. Reference to the appropriate bibliographic field where descriptions may be found are given for other subfields. Field 753 (Index Term--Uncontrolled) is a special-use classification data field whose subelements are described here.
