Maps are subjective cultural documents of great value in the study of local history. There are many types of maps in the holdings of institutions in northeastern Ohio. Selecting the right one for a particular research project will depend upon what type of information is being sought, but for most purposes the highly-detailed commercial atlas maps issued by the G.M. Hopkins Company, the Sanborn Map Company, or several minor firms in the nineteenth century will prove most useful.
