County maps can be found in the surveyor’s office of most courthouses and may sometimes be purchased or photocopied. They include historical county maps and contemporary county, township, and city maps. The Atlas of Historical County Boundaries: Indiana (New York: Charles Scribner’s Sons, 1996) may also be helpful.

The earliest Sanborn fire insurance map (see page 5) available for the state of Indiana is 1883. 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.
