Despite what a place is called on a work, the classification reflects the geographical area depicted.

A map if two named areas is classed under the first one named in the title proper. If there is no title, preference is alphabetical.

A map of three or more areas is generally classed in the next higher administrative or regional class number that includes them all. Except that a map of 3 or more cities may be classed under the first named or most prominent city, rather than under the county, state, etc. in which they exist.
