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?

Going through some batches of where I found what looks like blueline maps from the USGS .  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.
