Note above the differences for cities compared to counties and larger entities: - the subject code “P2” is not used in the LC call number (for cities, this is reserved for specialized/unusual maps)
- the subject code “D” is not used in the AGS number (for cities, this is reserved for specialized materials such as bus route maps or traffic surveys)
- the “roads” LCSH is not assigned
- For cities, we generally use LCGFT “Road maps” only for maps issued by AAA or a gas station, and/or for maps that specifically have “street map” or “road map” in the title. Otherwise use the LCGFT “Maps” (or a more specific heading as appropriate) instead.
