What is the best way to come up with copies of the Sanborn Fire Insurance Maps for one’s area? I see that some libraries have them but their access/availability seems restricted.
Out on the west coast we had “Factory Mutual” maps, which are the same thing. As for library copies, they may be accessed for Reference and copies made, usually for a fee. Explain what you are looking for and you can usually obtain access. John
Here in Corpus Christi, Texas, our public library has a digital subscription to TEXAS Sanborn Maps for its patrons. You have to go to the reference desk, show you are a card-carrying library patron (which usually means local resident) and they give you a password. Then you can access the digital Sanborn’s maps FOR TEXAS ONLY from library computers or home computer.
Our local history room has a microfilm reel with the Corpus Christi maps and several other Texas cities whose names begin the with letter “C” on the same reel. Sometimes that is better than the digital image, sometimes not. Does not take wait time for each image to come up, but it takes hand-cranking time to run through the reel to the image you want.
And then there is the deluxe which… I don’t know, maybe “serious” researchers can see them but they are, yes, restricted. Back in the mid 1970s, I got to handle the real original Sanborn’s book of maps, seemed like almost 3 feet square, with buildings colored in to show type of construction, all in 1" = 50’. That was quiite an experience.
It woould help to know what area you are interested in. The Sanbor maps for Florida can be found by googling PALMM.
I’m in Michigan and would be looking for Southern Michigan and Northwest Ohio.
From what i can see you need to be in either state and have a library card number, or need to go to a librabry and use their computer.
