Discover the stories of Ohioans who built our state’s farms, industries, businesses, schools, churches, social organizations, governments and communities - all in one place.

Whether you're a genealogist, historian, student or simply have questions about Ohio's past, the Ohio History Connection's Archives/Library is here to help. The Archives/Library is open Wednesday through Saturday, 10 a.m. - 5 p.m. There is no admission charge for visiting the Archives/Library.

The Archives/Library collects, preserves and makes available to the public written and graphic information concerning Ohio's history. As the State Archives of Ohio, it is also the designated repository for state government records of enduring historical value. An extensive collection of newspapers, photographs, manuscripts, books, maps and more are available to the public in our third-floor Research Room at the Ohio History Center in Columbus.

Collections available on-site and online

Visit the Archives/Library

Most of the items in our collection are kept in a storage area onsite, but not readily accessible to the public. We page items from the storage area and make them available to be viewed in the Research Room. When visiting, please register at the first floor Welcome Desk as you enter the Ohio History Center before proceeding to the Research Room on the third floor.
