NAME: Subentity Codes for Country of Publication and Geographic Area
SOURCE: Library of Congress
SUMMARY: This paper explores the establishment of codes for subentities other than the U.S., Canada and U.K. in the USMARC Code List for Countries and Geographic Areas. It suggests the definition of new subfields in field 043 (Geographic Area Code) and 044 (Country of Publishing/Producing Entity Code) for coding below the country level. Control of subentity codes is needed, and lists could be published in the relevant code lists as an appendix based on requests by countries.

12/15/96 - Forwarded to USMARC Advisory Group for discussion at the 1997 Midwinter MARBI meetings.
2/17/97 - Results of USMARC Advisory Group discussion - Participants agreed that there was a need to code for subentities. Discussion favored defining subfields in fields 043 and 044 for the full ISO code (once the ISO standard has been approved. An additional subfield should be added to allow for local extensions. A model for this technique is found in fields 033 (Date/Time and Place of an Event) and field 052 (Geographic Classification Code), which has separate subfields for geographic classification area code and geographic classification subarea code. LC should prepare a proposal for the next meeting for this change.
DISCUSSION PAPER NO. 98: Subentity Codes for Country of Publication and Geographic Area 1. BACKGROUND As MARC use expands, some countries would like to be able to code for subentities under the country level in the geographic area and country codes. Australia uses them and a query recently came to the Network Development and MARC Standards Office inquiring about the use of them for Brazil. It is likely that additional countries will request such expansion. In order to interchange records without preprocessing and to have customers in other countries inputting to other systems, the MARC code lists will need to accommodate this. It is desirable to standardize subentity codes, and they could appear as an appendix to the USMARC Code List for Countries and Geographic Areas so that systems can validate them. Any expansion to the lists will be based on requests of particular countries. 2. DISCUSSION The USMARC Code List for Countries contains a list of places with their associated two- or three-character lowercase alphabetic codes for presently existing national entities. In addition, subentity codes (i.e., for entities below the country level) for states of the United States, provinces and territories of Canada, divisions of the United Kingdom, and internationally recognized dependencies are included. The list allows the designation of place associated with an item. Country codes are used in 008/15-17 (Country of publication code) or field 044 (Country of Publishing/Producing Entity Code) as well as 535$g, 775$f, 851$g and 852$n. The USMARC Code List for Geographic Areas contains a list of geographic areas and their associated one- to seven-character codes. These include separate codes for countries, regions, and geographic features. In addition it includes first order political divisions of the United States, Canada, the United Kingdom, China, and Australia. The geographic area code is used in field 043 (Geographic Area Code). Country of publication and geographic area codes may be used in some systems to qualify searches. The three subentity lists in the USMARC Code List for Countries use one character for the country and two for the subentity. Because the 008 only has three character positions for country code and only 26 subentity lists could be accommodated using the current pattern, it is preferable to establish a subfield for subentities. In the GAC list only two characters are used for subentities. The GAC country codes are about 98% the same as the country of publication codes, and the GAC subentity codes are the same as those in the country of publication code list where they exist in the latter. Both lists use alpha characters only. There is a Draft International Standard for country subdivision codes currently undergoing review and ballotting. This is being circulated as ISO 3166 part 2 (Codes for the representation of names of countries and their subdivisions. Part 2: Country subdivision codes). It allows one, two, or three characters for the codes that can either be alpha or numeric. It is up to the country concerned to choose and suggest their own codes for the standard. There is not a consistent syntax for establishing them, nor is there consistency as to at what level they are established. Some countries use numerics, others alphas in the subentity code that is appended to the ISO 3166 part 1 country code. A one-to-one correspondence with country names in ISO 3166 part 1 is maintained. The USMARC Code List for Countries does not use the same country codes as the ISO list, although it does remain entity compatible. In many cases the ISO list cannot be used, because the same subentity codes should be used for both country and geographic area codes, and the ISO list does not meet the constraints of the GACs. When a subentity list is requested by a country, the codes would have to be worked out considering various factors: the ISO list, the subentities in GAC that are not in the country list (i.e., China and Australia), and the preferences of the country. Subentity codes would only be established if requested by a country. They would be published in the USMARC country code and geographic area code lists as an addendum so that systems can validate them and accept records using them. However, LC may not use them in its records and would not be responsible for maintaining the lists, for instance adding new ones or changing existing ones. 3. QUESTIONS FOR FURTHER CONSIDERATION 1. Should a new subfield be established for subentities in field 043 and 044? 2. Should the ISO 3166 part 2 list be considered in establishing subentities? 3. If lists of subentities were published as an addendum to the USMARC Code List for Countries and USMARC Code List for Geographic Areas, what impact would this have on systems that would have to validate them?
