710 Index Term - Corporate Name

Field definition and scope:

Field 710 contains a corporate name or the corporate name portion of a name/title field used as an index term that supplements terms derived in the MARC record. The name may be referred to in the classification number and caption in field 153 (Classification Number).

The field may be used to link a classification number with a related controlled corporate name heading. The values in the second indicator position or the data in subfield $2 (Source of heading or term) identify the subject heading system or thesaurus used by an institution to formulate the corporate name index term. Terms not controlled by a thesaurus or authority file are contained in field 753 (Index Term - Uncontrolled).

Field 710 is repeatable.
