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.

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

 
ǂa Geographic area code

Geographic area code. Use a separate subfield ǂa for each code. Use the following guidelines:

  • Assign a geographic area code if a subject heading assigned to the item has a geographic term in any form or position.

  • Assign codes for histories and criticisms of national literatures and for individual or collected works of literature if the subject headings show geographical content.

  • Assign codes for collective national and local biographies. Do not assign codes to works of individual biography and autobiography, unless a subsequent subject heading cites the geographic entity.

    043     n-us-il
    245 0 0 New Salem, early chapter in Lincoln's life.
    651   0 New Salem (Menard County, Ill.) ǂv Biography.

  • 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.

ǂb Local GAC code

Local expansion of a geographic area code. Use a separate subfield ǂb for each local GAC code. The source of the code is indicated in subfield ǂ2 . It is recommended that standard geographic area codes also be included in subfield ǂa for international exchange and understanding.

ǂc 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 .

When creating MARC bibliographic records according to RDA or AACR2, see MARC Code List for Geographic Areas 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.

ǂ0 Authority record control number or standard number

For information about subfield ǂ0, see Control Subfields.

ǂ1 Real World Object URI

For information about subfield ǂ1, see Control Subfields.

ǂ2 Source of local code

Source from which the local code was assigned. Used only when subfield ǂb is used to indicate a local GAC code. Code from Geographic Area Code and Term Source Codes.

ǂ6 Linkage

Data that link fields when non-Latin script is entered. This subfield is system supplied and does not appear in OCLC online displays. Do not add subfield ǂ6. For more information about subfield ǂ6, see Control Subfields.

ǂ8 Field link and sequence number

For information about subfield ǂ8, see Control Subfields.
