The Kentucky Historical Society is releasing a smartphone app so users can find out more about the Commonwealth's historic sites. The Explore Kentucky History app connects historical markers, related items in the Historical Society's collections and user-submitted images and stories to points of interest on a map. The information is then grouped together into tours, with a Civil War-themed tour the first available. The KHS says it hopes Kentuckians and local history groups will participate, submitting images and stories. The app is available for free. The information is also accessible online at http://explorekyhistory.ky.gov.
