www.ohiohistorycentral.org : The Ohio Historical Society's online encyclopedia of Ohio history. This continually evolving site features over 2,000 entries related to Ohio's natural history, prehistory, and history. It also contains hundreds of images and multimedia files.
www.historyplace.com : A wonderful history site, including photos, speeches, History in the USA, This month in history, and Main Exhibits. They also have a Personal Histories feature, that contains a real life history story. Not good for researching, as the site does not have it's own search engine.
www.altapedia.com : All types of maps and brief text on every country.
