Tracing Fields: Simple Cross References

Tracing Fields: Simple Cross References (Tracing and Reference Fields - General Information )

Guidelines for applying subfields $i (Reference instruction phrase) and $w (Control subfield) in the 4XX and 5XX fields, as well as examples of simple cross reference displays are provided below. All other content designators in the 4XX and 5XX fields are defined in the specific fields and in the X00-X85 General Information sections for each type of heading.

Simple cross references are generated for display from tracing fields. The following information is arranged by the source of the reference instruction phrase used in the cross reference: tag related, subfield $i, and subfield $w.

Tag related reference instruction phrase

A reference instruction phrase such as see: or search under: may be implicitly associated with a 4XX field tag and may be used to generate a display of a cross reference.

A reference instruction phrase such as see also: or search also under: may be implicitly associated with a 5XX field and may be used to generate a display of a cross reference.

Subfields $i (Reference instruction phrase) and $w (Control subfield)
