You will surely hear from some experienced map catalogers.  However,
what you describe is not unique to maps, and the dilemma you find
yourself in is because of different content in each volume, not so much
that the content is cartographic in nature.

The differences if they get described in separate records are going to
be in fields that for the most part are not unique to the rules for
cartographic materials.  It will be in note fields and some others.  I
would draw on your rare book cataloging experience to make your
decisions here.  As you suggest, the two volumes could represent two
copies of the same work with content added later to one of them.  On the
other hand, based on information from other sources, they could
represent two editions from the same publisher, with similar content in
both, but with added content in one of them.  But these all represent
*bibliographic* rather than *cartographic* concerns.

hello all,
I was hoping someone might be able to help me with this dilemma.
I have 2 copies of: Atlas of the Hudson River Valley from New York City
to Troy / F.W. Beers, NY : Watson & Co, 1891.
Both have 35 numbered "section" double plates of Hudson River Valley,
and both have extra double plates, just not the same ones.
One has 5 extra maps detailing Newburgh, NY and the other has about 10
extra maps detailing Englewood and other sections of NE NJ. so, the
physical descriptions and subject (to an extant) would differ. do these
get separate records? why would they be issued this way? unless they
weren't?
One, with the extra Newburgh maps, is in orignal publishers boards.
the other, with the extra NJ maps, has been rebound.
also, if I don't include the scales for the extra maps, there are 2
consistently used throughout the atlas, so they would be listed in the
record. If I do include the extra plates, it becomes scales differ.

I am a rare book cataloger with a limited experience cataloging maps.
any advice would be appreciated.
