The Library of Congress has many productive partnerships with peer institutions and affiliates, and their thirty-year partnership with the American Congress on Surveying and Mapping (ACSM) has been quite fruitful. Designed to complement a current in situ exhibit at the Library of Congress’s headquarters, this online exhibit explores cartography, surveying, and geographic information systems in their full glory. The maps provide a broad overview of the history of surveying, as they begin with maps of George Washington’s farm created in 1760 and conclude with offerings created in 1999. The selection of maps is quite catholic in its scope, as it includes an intriguing map of the University of Oregon campus at night, a map from the popular board game “Carmen Sandiego”, and a relief map of Crater Lake. After all this, even the most casual visitor may find themselves with a renewed or newfound interest in the field of geography.
