The Indiana State Library has a few Sanborn fire insurance maps on microfilm; the Indiana University Geography and Map Library in Bloomington, however, has an almost complete collection of these maps. Atlas and plat maps for each county and township dating 1875 to present are at the Indiana State Library. County maps show roads, railroads, churches, cemeteries, and schools.
