Reference record (008/09 code b - untraced or code c - traced):

An authority record in which the 100-155 field contains an unestablished name or subject . A reference record also contains either a 260 (Complex See Reference - Subject) , a 664 (Complex See Reference - Name) , or a 666 (General Explanatory Reference - Name) field to guide the user to the established form. Separate codes are defined in 008/09 for traced (code c) and untraced (code b) reference records. The distinction depends upon whether the heading in the 1XX field in the record is also given as a see from tracing in a 4XX field in another authority record.
