FIELD DEFINITION AND SCOPE

Text for reference notes with historical information for names that is used in an established heading record when more information is needed about the relationships that exist among three or more established names (usually corporate names) than can be adequately conveyed by simple cross references generated from 5XX See Also From Tracing fields in the established heading records.

May also contain text describing the subject entry treatment for works about the various related headings. The field is appropriate only in an established heading record.

1XX field in the record contains an established heading referred from. Field 665 contains the history of the name changes and the other established headings referred to. The established heading in field 1XX is also traced in a 5XX field in the established heading records for the headings referred to in field 665. Subfield $w/3 (Reference display) in each of the tracing fields may contain code d (Reference not displayed, field 665 used). Code d indicates that the generation of a simple cross reference from the 5XX field should be suppressed.

Cross references may be generated from the 1XX and 665 fields. A reference instruction phrase is incorporated into the text of subfield $a. Examples of complex cross reference displays are provided in the Tracing and Reference Fields-General Information section.
