Subdivision:
Code d (008/09) indicates that the 18X field contains an unestablished heading that is the authorized form of a general or chronological term or a geographic name that is authorized for use as a subject subdivision in a subject access point in a bibliographic record. The record may also contain 48X / 58X tracing fields for variant and related subject subdivision terms.
If the subdivision may also be used as an established heading, code f
is used in 008/09 when an organization uses one authority record to convey this dual function.
When a subdivision may also be used as an unestablished reference term, code g
is used when an organization uses one authority record to convey this dual function.
A 15X heading
field contains the heading in a code f or g record.
