663-666 Complex Name References

Definition and scope:

Fields 663-666 contain information about unauthorized forms of name headings, different authorized forms of name headings, and other variants not chosen as the authorized form when the relationships cannot be adequately conveyed by one or more simple cross references.

The see reference note fields (260, 664, and 666) are used in reference records to lead from an unestablished heading to established headings. The see also reference note fields (360, 663, and 665) are used to lead from an established heading to other established headings.

Cross reference displays generated from the reference note fields are complex cross references. In a complex cross reference display, the content of the 1XX field of a record is the heading referred from, and, following a reference instruction phrase, the reference note field contains the heading(s) referred to.
