Our print map collection contains approximately 350,000 maps, as well as atlases and map-related reference materials. Most of the maps date to the second half of the 20th century and were published by U.S. government agencies and acquired through the Federal Depository Library Program. The collection covers the the United States and its territories and possessions, and many areas outside of the United States.
The collection also includes map- and geography-related reference materials, such as indexes, cartobibliographies, gazetteers, dictionaries, catalogs, books and periodicals.
