Explanatory text and headings referred to that are required when relationships exist between unestablished and established subjects that cannot be adequately conveyed by one or more simple cross references generated from 4XX See From Tracing fields in the established heading record. A phrase such as search under: may be generated for display.
Appropriate only in a traced or an untraced reference record or a reference and subdivision record for subjects.
1XX field in the record contains the unestablished subject heading referred from. Field 260 contains the explanatory text for the see reference and the established headings referred to. The unestablished heading contained in field 1XX of the reference record may either be traced in a 4XX field or noted in a 681 field (Subject Example Tracing Note) in the record for each heading referred to in the 260 field.
Cross reference display may be constructed from the 1XX and 260 fields of the reference record. Reference instructions may be a combination of a tag-related phrase and text in subfield $i. Examples of complex cross reference displays are provided in the Tracings and References—General Information section.
