Summary: This page provides examples of call numbers (both Library of Congress and AGS) for road maps, using MSU's in-house modifications, as well as example subject headings for road maps. It also details differences in call numbers and subject headings as applied to maps of cities, vs. maps of larger areas.

Road maps of cities
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 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.
