FIELD DEFINITION AND SCOPE

Appropriate only in an untraced reference record.

1XX field in the record contains the unestablished data element referred from. Field 666 contains the explanatory information. The heading in the 1XX field is not traced in a 4XX field in any established heading record for names beginning with the specified characteristic.

Cross reference display may be generated from the 1XX and 666 fields of the reference record. 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.
