Maps are a major resource when researching history of any place. Online Maps, while lacking the touch of a printed map, offer zoom, scaling, and sometimes search features to facilitate using the map. There are many kinds of maps. Most maps show political divisions (country, state/province, county, township, etc.). There are specialty maps that focus on an aspect of the location; Topographical maps, Road, Railroad, River maps are common. While we are most familiar with sheet maps, maps bound in books and atlases present a collection of maps.
The Delaware County Historical Society’s Cryder Research Library collection includes maps and atlas books along with directories for both Delaware City and Rural areas. The Society’s Online Catalog lets you search for available resources, for example Search for Maps. Visitors are welcomed to the Library, during open hours, view and research with our maps and other resources.
In our research, our volunteers have found Online other Maps of Ohio, Delaware County, and places in the county. To assist our members, friends, and visitors we offer this page of online maps that we found useful.
