This site focuses on maps of the United States and North America, but it contains a sizeable number of maps from other parts of the world. The maps are organized into seven thematic categories: “Cities and Towns,” “Conservation and Environment,” “Discovery and Exploration,” “Cultural Landscapes,” “Military Battles and Campaigns,” “Transportation and Communication,” and “General Maps.” Most maps range in date from the mid-17th through early 20th centuries, though the “General Maps” section contains 52 contemporary non-U.S. maps. “Cities and Towns” contains about 40 non-U.S. maps. Of particular interest, however, is the collection of 23 maps of Washington, D.C., ranging in date from 1791 to 1994. “Cultural Landscapes” contains a section of 20 maps of Liberia dating from 1830 to 1870. It also contains 50 other non-U.S. maps, including 20 maps of Mexico and Mexico City. “Military Battles” has 10 maps of the Caribbean islands dating from the Revolutionary War era. The “General Maps” section, however, has the largest collection of non-U.S. maps, with about 150 ranging in location from Iraq to Ireland to Russia. It includes a series of 10 maps of Palestine ranging in date from 1696 to 1783, and also 12 world maps dating from 1565 to 1942. Each section may be searched by keyword or browsed by subject, creator, geographic location, index, and title. Information provided for each map image includes a thumbnail, the name of the cartographer/engraver, place and date of creation/publication, comments on perspective, and information for locating the map at the library. In addition, all the images may be zoomed for detailed viewing.
