Repository access note: Selected microfilm holdings from the Ohio Genealogical Society’s published 2012 inventory. This is a historical inventory: confirm that the film is still available, along with current visit, copying and access conditions, before relying on it. These are holdings at the society, not a complete county courthouse inventory. Census spans do not imply that every census survives; the 1890 population census is largely lost. Some original catalog titles contain historical terminology.

Sources: the catalogs and repository descriptions linked on the entries above. Selected inventories do not establish complete coverage of every record type or online access to original documents. Read the repository access note for source dates and limitations.
