4XX See From Tracings

Definition and scope:

Fields 400-485, the See From tracing fields, are used to identify unauthorized forms of headings and other variants not chosen as an authorized form.

Tracing fields lead directly from one heading to a single other heading. A 4XX field leads from an unauthorized heading to an authorized heading. The 4XX and 5XX fields are used only in established heading records and subdivision records.

Cross reference displays generated from the tracing fields are called simple cross references. In a simple cross reference display, the content of the 4XX or 5XX field is the heading referred from, and, following a reference instruction phrase, the content of the 1XX field is the heading referred to.

For more information about tracings and references, see:
