Definition

Contains the geographic area code (GAC), which is an aid to a subject approach to the item. It provides a hierarchical breakdown of geographical and/or political entities.

You may base your code selection on geographic names and/or subdivisions in 6xx subject added entry and index term fields. Enter codes in order of importance, usually the same order as the geographic names and/or subdivisions in the 6xx fields.

Each geographic area code has seven character positions, which use lowercase letters or hyphens. All seven positions must be filled or the field will fail validation; complete any unfilled character positions with hyphens so the entry is seven characters long. See MARC Code List for Geographic Areas (http://www.loc.gov/marc/geoareas/).

If the item deals with an area that is too specific to be represented by a code, assign the code for the next larger jurisdiction or area.

1st Indicator

Subfields

 
‡a Geographic area code

  • Do not assign geographic area codes for linguistic works. For example, in the subject heading Sermons, German, the adjective applies to the language and does not justify a geographic area code.

‡b Local GAC code

Local expansion of a geographic area code. Use a separate subfield ‡b for each local GAC code. The source of the code is indicated in subfield ‡2 . It is recommended that standard geographic area codes also be included in subfield ‡a for international exchange and understanding.

‡c ISO code

A code taken from the ISO 3166, International Organization for Standardization's Codes for the Representation of Names of Countries and Their Subdivisions–Part 1: Country Codes or Part 2: Country Subdivision Codes (http://www.iso.org/iso/home/standards/country_codes.htm).

When creating MARC bibliographic records according to RDA or AACR2, see MARC Code List for Geographic Areas (http://www.loc.gov/marc/geoareas/) for the list of codes. Each geographic area code has seven character positions composed of lowercase letters and hyphens.

When creating Dublin Core® records, non-MARC code lists may be used.

‡0 Authority record control number or standard number

For information about subfield ‡0, see Control Subfields.

‡2 Source of local code

Source from which the local code was assigned. Used only when subfield ‡b is used to indicate a local GAC code. Code from Geographic Area Code and Term Source Codes (http://www.loc.gov/standards/sourcelist/geographic-area.html).

‡8 Field link and sequence number

For information about subfield ‡8, see Control Subfields.
