I would use the following criteria to make a determination. * Historical significance: o Was additional information added that differs from the originals, perhaps handwritten notes or markings, that suggest how the maps were used? o Is there any identification of the company that printed the blue line maps that at least documents the printer's existence and function? o Can you determine when the blue line version of the maps were printed? * Is your organization interested in documenting map printing processes and/or the era of blue-line map printing? * Do you have space to store the maps and does their condition and/or content warrant preservation?

They are blue lines with no additional data 100,000 scale maps...it is literally just the geography with a few place names on what looks like newsprint paper. Do maps collections keep such maps? How useful are they? Any help you can give me would be most appreciated. ---------------------------------------------------------------------- ,-~~-.___. / | ' \ "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.
