A collection of more than 70,000 maps printed as part of the Congressional Serial Set. With the High-Resolution Maps Module, more than 50 percent of these are scanned at high resolution enabling users to see and download the smallest details on the map. The rest of the maps are mostly outline maps and would not benefit from being scanned at high resolution. Several Executive Branch agencies are the most prolific publishers of the maps including the Army Corps of Engineers and the U.S. Geological Survey. More information about searching the collection.
