Subject: 2 records for 2 issues of same atlas?

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.
