I was under the impression that the Sanborn Map Company had stopped producing new maps at about that date. Now Chadwyck-Healy and UPA a re offering post-1960 Sanborn maps for sale on microfilm. Are these new maps or just corrected versions of old maps? How extensive is their coverage? Are they worth buying? Also, what are insurance companies doing? Do they still make much use of these maps? They must have their records computerized by now. If they still use maps at all, it would seem logical for them to maintain them in digital form.
