FIELD DEFINITION AND SCOPE

Explanatory text and the headings referred to that are required in a reference record for names when relationships exist between an unestablished name and one or more established names that cannot be adequately conveyed by simple cross references generated from 4XX See From Tracing fields in the established heading records.

Appropriate only in traced reference records for names.

1XX field in the record contains an unestablished name referred from. Field 664 contains the explanatory text for the see reference and the established headings referred to. The unestablished heading in field 1XX is also traced in a 4XX field in a record for each of the established headings referred to in field 664. Subfield $w/3 (Reference display) in each of the 4XX fields contains code b (Reference not displayed, field 664 used). Code b indicates that the generation of a simple cross reference from the 4XX field should be suppressed.

Cross references may be generated from the 1XX and 664 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.
