Guidelines for Usage: 663 Complex See Also Reference - Name

NACO LSP Usage:

Simple cross references are preferred over complex cross references . Field 663 is used only when the relationship of other names to the name contained in the 1XX Heading cannot be adequately expressed by simple see also cross references constructed from field 1XX and multiple 5XX See Also From Tracing fields.

LC NACO must be consulted before this field is used.

LC Usage:

LC uses field 663 only when the relationship of other names to the name contained in field 1XX cannot be adequately expressed by simple see also cross references constructed from field 1XX and multiple 5XX fields.

LC did not implement field 663 until March 1984. Before that time, LC used field 664 (Complex See Reference - Name) for all complex reference situations. These reference records contain an established heading in the 1XX field and a see also reference in field 664. The evaluation of references process in an existing authority record may result in the deletion of the reference record and either the addition of field 663 to the related established heading record or the adjustment of the subfield $w coding in the existing 5XX fields.
