Louise,
Taking into account that different catalogers/collection managers have the latitude to make their own classification choices for individual collections and that's okay, to me first and foremost this is a topographic map. A map showing the topography of a geographic region surrounding but also including the city. As such, I would class something like this as a .C2 map. OR, again depending on where you want the map to "live" with other maps in your collection (and you don't care about the topography aspect) I might just leave it as a general map of the region and then as you do include "Region" in the subject heading for the city.

Hello collective wisdom,
I recently had a conversation with a map cataloger at the University of Chicago, and we were debating classification of a single topo quad sheet for Allepo, Syria. My custom has been to just classify to the city, and for the first subject heading I use "City x (country) Region--Maps. At U of Chicago, they classify individual sheets to the city with a subject designation of "A1."
I found this procedure to be from the ca. 1992 Map Cataloging Manual which says:
Subject Cutters:
A1 City Regions and Suburban Areas:
The city region and suburban are aspect of A1 applies only when the map in hand is not useful as a city map. Otherwise class under the city without A1.
Maps classed in A1 as city regions or suburbs have the subject heading [City] Region--Maps or [City] Suburban Area--Maps as appropriate (8)
More detailed maps of cities and metropolitan areas are not classed under the A1 subject Cutter.
Any other subject Cutter takes precedence over A1.
Thanks a lot,
Louise
