All, The digitization and online placement of the Sanborn Fire Insurance Maps at the Library of Congress is an ongoing project. Michigan maps pre-1900 are now available, per the below Library of Congress announcement. The Sanborn Fire Insurance Maps are a great source of historical data to genealogists, researchers, etc. For that reason you may wish to consider making them available to your patrons, if you have not already done so.
