581 See Also From Tracing - Geographic Subdivision (R) (Variable Data Field)
Field 581 contains a tracing for a geographic subdivision see also from reference. It is used in an established heading record or an established heading and subdivision record to trace a see also from reference from an authorized geographic subdivision to a related established heading.
The National level record requirement for this field is Mandatory if applicable.
Field 581 is repeatable.
Guidelines for applying content designators:
The content designators identify the subelements occurring in geographic subdivision headings constructed according to generally accepted thesaurus-building conventions (e.g., Library of Congress Subject Headings, Medical Subject Headings).
A geographic subdivision is used as a subdivision portion of an extended subject or index term access field in bibliographic records.
A geographic name that is used as the lead element of an established heading record is contained in a 151 (Heading - Geographic Name) field.
