664  Complex See Reference - Name (NR)  (Variable Data Field)

Field definition and scope:

Field 664 contains the explanatory text and the headings referred to that are required 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 established heading records.

Field 664 is appropriate only in traced reference records for names.

The 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.

See example under the description of subfield $t (Title referred to).

A cross reference 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 Reference Note Fields:  Complex Cross References.

The National level record requirement for this field is Optional.

Field 664 is NOT repeatable.
