Application of the Codes

Geographic area codes are assigned in bibliographic records to bring out by code the geographic areas that appear or are implied in the headings assigned to the work being cataloged. Generally, codes are assigned for headings in a subject added entry for a geographic name (field 651 ) or headings in other fields which contain a geographic subdivision (subfield $z ). Codes are also assigned for headings representing ethnic groups, nationalities, civilizations, topics qualified by ethnic groups or nationalities, individual named entities including corporate bodies, and events.

Geographic area codes may be included in authority records for geographic areas associated with the established heading of the record.

The following guidelines describe application of the codes in specific situations:
