FIELD DEFINITION AND SCOPE

Subject added entry in which the entry element is a uniform title.

Subject added entries are assigned to a bibliographic record to provide access according to established subject cataloging principles and guidelines. Field 630 may be used by any institution assigning subject headings based on the lists and authority files identified in the second indicator position or in subfield $2 (Source of heading or term).

Title used in phrase subject headings (e.g., Bible and atheism) is contained in field 650 (Subject Added Entry-Topical Term).

GUIDELINES FOR APPLYING CONTENT DESIGNATORS

Description of the first indicator position and all subfield codes, as well as input conventions for the 630 field are given in the X30 Uniform Titles-General Information section.
