The Huebinger series of automotive publications were popular a century ago as adventurous motorists braved the primitive roads and uncertain terrain of Iowa and beyond. Noted landmarks on these road-maps include schools, houses, churches, piles of stumps, unusual rocks, cemeteries, and windmills. Today, these map collections are actually history books showing how towns and cities have developed, roads have changed, and some communities have disappeared.
The State Historical Society of Iowa is in the process of making more of these records available online. Currently they have placed online death records for 87 counties with various dates for all of them which fall between 1917 and 1939.
