Tracing and Reference Fields - General Information

Tracing and Reference Fields - General Information: 2XX, 3XX, 4XX, 5XX, & 663-666 (Variable Data Fields)

Definition and scope:

The Tracing and Reference Fields include tracing fields (4XX See From Tracing , 5XX See Also From Tracing ) and reference fields (260 , 360 , 663-666 ).

A cross reference leads from an unauthorized heading to an authorized heading (see reference) or from one authorized heading to another (see also reference). Actual cross references are generally not carried explicitly in authority records. Instead, variant form and related headings are carried in authority records in either tracing or reference note fields. Cross reference displays may be generated by combining the contents of a tracing or a reference note field and the 1XX field of a record.

Tracings and References information, guidelines, and examples:

Tracing Fields (Definition)

Tracing Fields: Simple Cross References (Guidelines for using a tag related reference instruction phrase, subfield $i, and subfield $w in 4XX and 5XX fields, including examples of simple cross reference displays.)

Reference Note Fields (Definition)

Reference Note Fields: Complex Cross References (Guidelines for using a tag related reference instruction phrase with subfield $i in 2XX-3XX fields and subfield $a in 663-666 fields, including examples of complex cross reference displays.)

Input Conventions (Guidance and clarification for application)

The general input conventions for the 4XX and 5XX tracing fields are provided in the specific fields and in the X00-X85 General Information sections for each type of heading. The input conventions for the reference note fields (260 , 360 , and 663-666 ) are provided in the description of each field.
