The Norman B. Leventhal Map & Education Center at the Boston Public Library, created in 2004, is a nonprofit organization established as a public-private partnership between the Library and philanthropist Norman Leventhal. Its mission is to use the collection of 200,000 maps and 5,000 atlases for the enjoyment and education of all through exhibitions, educational programs, and a website that includes more than 10,000 digitized maps at collections.leventhalmap.org. The map collection is global in scope, dating from the 15th century to the present, with a particular strength in maps and atlases from the New England region, American Revolutionary War period, nautical charts, and world urban centers.

The Leventhal Map & Education Center is ranked among the top ten in the United States for the size of its collection, the significance of its historic (pre-1900) material, and its advanced digitization program. It is unique among the major collections because it also combines these features with exceptional educational programs to advance geographic literacy among students in grades K to 12 and enhance the teaching of subjects from history to mathematics to language arts. The collection is also the second largest in the country located in a public library, ensuring unlimited access to these invaluable resources for scholars, educators, and the general public.
