Susan,
    You are correct about the green being forest.  USGS and we are
working on a joint inventory project and this is referred to as
"woodland tint".  You are also correct that it is often the only
difference between two sheets; all other metadata will be the same.  Our
project is creating a database of metadata for the USGS historic quads,
  and many of the USGS maps are up in the National Map
(http://nationalmap.gov/historical/).  There is a lot of good
information in the FAQ there.

   Please feel free to contact me if you have more questions.  The
Library of Congress currently has no plans to do sheet level cataloging
on the USGS quad maps, but we are working on a complete inventory of our
holdings.

Subject: cataloging question -- noting presence of green plate on usgs topos

Hello,
I have a question that I've been curious about for a while and has
recently come up again in a project I'm working on. Some USGS topos have
a green layer (presumably indicating forest cover?) -- often this green
plate is the only feature different from an identical map (same dates,
etc.). I was wondering if anyone has noted this "green plate" in
cataloging individual sheets, and if so, which field and what language
you used to describe it.
Thanks in advance!
