This has to be measured in the context of your collection and your institution's purpose. One suggestion, however, is to create a collection of interesting items discovered during your weeding. How about a 'Map Example Collection' or 'Printing Process Collection' that addresses the maps that you feel are significant into a thematic grouping? This collection could be a 'bucket' into which you put potentially interesting things until you get some time to research further. Your weeding process would be able to continue, thereby satisfying some, and interesting specimens from the collection would be saved, thereby satisfying others.

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. ----------------------------------------------------------------------- ,-~~-.___. / | ' \ "The needs of the many outweigh the needs of ( ) 0 the few or the one." \_/-, ,----' ==== // Mr. Spock / \-'~; /~~~(O) Star Trek: The Wrath of Khan / __/~| / | =( _____| (_________| Carlos A.
