The Archives at the Ohio History Connection are a treasure trove of Ohio history. Open to the public, the library collection includes birth and death certificates, prison records, county directories, military rosters and so much more. The main room of the library houses only .005% of the entire collection, the rest lies in the stacks beyond (they span several stories of floor to ceiling shelves). The newspaper collection dates back to 1795, and visitors can browse through microfilm to read stories from local papers.
The library and archives are frequented by researchers and genealogists. Materials are also used in litigation to settle land disputes and by veterans to prove service with the help of military rosters. The library offers reference services via email and in person, and the library provides access to popular databases including Ohio Memory and Chronicling America.
