Robin, LC started scanning them about 25 years ago with the aim of putting them all online (full color)-but that has taken a long time. ProQuest saw a market for selling the images. ProQuest made their scans from microforms -so I believe that they are only black & white. As you can see, color is important with Sanborn Maps. Best wishes, Scott R. McEathron, M.A., M.L.I.S.
