The Kentucky Maps Collection (http://digital.library.louisville.edu/collections/maps ) currently features three atlases of Louisville and Jefferson County, Kentucky, from 1876, 1884, and 1913. These maps show inter-city and commuter rail lines, waterway crossings, and private and public properties, from a time before interstate highways crisscrossed the region and the metropolitan area expanded throughout the county. Innovative use of the Google Maps tool permits users to access the historic maps through a current map, providing dramatic visual testimony to the changes over time. This digital collection will eventually expand to include other historic maps from the Libraries' collections.
