I posted the inquiry about how to determine if a map is rare due to a
possible weeding project in our maps collection.  I would really like to
know how to identify such maps.  We are a Federal documents depository
and we have quite a collection of maps.
For example:
--Are the */Geologic Atlas of the United States/* that were published in
the late 1800 and early 1900s be considered rare though quite a few
depository
      collections may have them.
--How about the early 15 minute series maps. are they also considered rare?
--The other day while going through the collection, a student worker
found a USGS map that included a black and white photo image (looked
like a satellite
      image).  Well, the map had the following phrase printed on the
lower right corner of the map: */Experimental Issue/*.  Though not old,
could this be
      considered rare because it was the first time they tested something
new?
We don't want to remove something that could be valuable.
