Here is an interesting tool for historic resource which we have recently discovered…

HistoricMapWorks.com is a compendium of historic maps of locations world-wide that can be accessed online for free, with larger images, prints, etc. available for purchase.  The site features approximately 220 maps of Ohio counties and communities, including full versions of several period county atlases and panoramic maps of several Ohio cities.  Many of these 19th century county atlases feature pages of photographs or drawings of important buildings in larger county communities.  To reach the Ohio section, click on “Browse,” “North America,” and then “Ohio.”  Individual links for county atlases then take you to an overall page, with individual tabs for Directories, Histories, Illustrations, etc..
