The library map collection, the largest in the Pennsylvania State System of Higher Education, is located on the lower level of the library. It provides world-wide map coverage with an emphasis on Pennsylvania and the United States and includes general maps, U.S. Geological Survey topographic maps, aerial photographs and satellite imagery, historic map reproductions, plastic raised relief models, Braille maps and atlases, and CD-ROMs. The map collection contains the complete set of Sanborn Fire Insurance Maps of Pennsylvania on microfilm; digital access to the Pennsylvania Sanborn maps is also available.
