UMD Map Collections

McKeldin Map Collection

The map collection at McKeldin Library is located on the fourth floor.  We have over 350,000 maps, most of which were produced by U.S. government agencies and came to us through the Federal Depository Library Collection.  Coverage includes all of the U.S. states, most of the U.S. territories and possessions, and some areas outside of the United States.
