Preble County Room - Genealogy

Preble County Room

The mission of the Preble County Room is to provide genealogical and historical resources and various related services to our patrons. We connect the present to the past through the use of books and other media of genealogical and historical interest. The collection includes information about Preble County, its contiguous counties and those areas of migration to and from this area as space and finances permit.

Collection and Donation Policy

The primary scope of the collection is Preble County history and information about its residents. Published or unpublished genealogies which include Preble County families are welcome. We will also accept materials on neighboring counties, Preble Countians and areas where they moved to after leaving Preble County. We do not accept artifacts and recommend they be donated to the Preble County Historical Society.

Once an item is accepted by the Preble County Room, it becomes the property of the Preble County District Library. Materials are never removed from the collection except for repair, replacement, or preservation. We are willing to make copies of unpublished materials, works with expired copyrights, documents and photographs and return the originals to the owner.

Other formats of materials accepted include, but are not limited to:

  • Bible family pages - please provide a copy of the Bible’s title Page and the owner's name
