A collection of non-copyrighted "electronic maps" are available for viewing and downloading (in JPEG and GIF formats) from the Perry-Castaneda Library (PCL) of the University of Texas at Austin. The maps are indexed by geographical region and country, and dates range from the early 1800s to as late as 1995. In addition to PCL's own collection there is a link to "other map-related web sites" which has hundreds of links to cartographic reference sources, weather maps, and US city and state maps, to name a few.
