The earliest Sanborn insurance map for Ohio is an 1875 map for Zanesville, held by the Ohio Historical Society. Consult the Newberry Library, Checklist of Printed Maps of the Middle West to 1800 (2 vols. Boston: G. K. Hall, 1980), although this is not an inclusive listing for maps in Ohio. It does not, for example include those held by the Western Reserve Historical Society (see Archives, Libraries, and Societies). Many academic and other libraries in Ohio have at least a partial collection of Sanborn maps on microfilm, and many libraries offer online access to Sanborn maps for the entire state of Ohio. Other excellent sources include:
