CityOrCounty

Part of the Locations hierarchy, CityOrCounty establishes the position of places larger than a building or site, but smaller than a state or region. TGN terms that are qualified “inhabited places” usually fit here. Generally, the form of the place name will follow the Authority from whence it came. There are two local exceptions to this rule: Entries for Oregon cities are qualified by their county, i.e. “Eugene (Lane)”, and Japanese cities are qualified by their prefecture, i.e. “Yonezawa (Yamagata-ken)”. In the case of Japanese cities, the established hierarchy leaves out a very important subdivision between StateRegion and CityOrCounty, so this compromise was made. It is important that the primary key for the StateRegion be entered accurately, or the City will not appear in the Locations entry fields of the Work record.

Note: The Locations hierarchy may contain “unknown” as entries. These are used only when you have a named entity smaller than a continent wherein you cannot establish one or more parts of the hierarchy ABOVE it. No Location hierarchy should end in “unknown.”

Field Name	Local Usage	Notes
Term Source	Pull-down menu	Standard short list of online Authorities
Ref ID	Use for Authority reference numbers, as source	The identification given to the authority record by the authority source
City or County	Use Title Case; use parentheses for county qualifiers, i.e. “Eugene (Lane)”	The only entries that regularly use qualifiers are cities in Oregon, followed by the county, or cities in Japan, followed by the prefecture.
State Region ID	Enter from StateRegion Table	Primary key for the StateRegion facet
City ID	Auto-generated	Primary key for the CityOrCounty facet
Extent	Pull-down menu
Local Extent	Free text	Since the Extent is an unmodifiable field (green), but does not contain all possible extents, use this field in conjunction with the Extent field to indicate a more precise extent. In other words, if you need to use Local Extent, you must choose the closest entry under Extent as well.
Portal	Auto-entered, editable	Auto-fills with records from the next tier down in the hierarchy (in this case SiteInstitutionBuilding.)
Print Source	Pull-down menu or MLS format	If the Term Source is Print or Web, you must indicate the book or URL. The pull-down option shows all Source records. Click in the box and type if the source is not part of the Source table.
