The Library's collection of maps is primarily designed to meet the recurring needs of architecture, planning, and design students, and includes atlases, street maps, current digital Sanborn maps, historical Sanborn maps, and USGS topographical maps.
Atlases on a wide variety of subjects are catalogued in PrattCat and may be found in the Reference and Ready Reference sections of the Reference Reading Room on the first floor.
The Library owns USGS topographical maps for the states of New York, New Jersey, and Connecticut. These are located in the map cases inside the first-floor stacks, with the exception of the quad index and maps for New York City, which may be accessed upon request at the Reference Desk. Topographical maps are not listed in PrattCat.
A variety of street and transit maps for the boroughs of New York City, as well as selected national and international cities, may be accessed upon request at the Reference Desk. Some but not all of these maps have been catalogued in PrattCat.
Current digital Sanborn maps for Brooklyn and Manhattan are available at selected public-access computers on the first floor. A guide to using the database is available at the Reference Desk. The Library also owns black and white print volumes of Brooklyn and Manhattan dated 2005. The indexes for these are located at the Reference Desk while the individual plates are kept at the Circulation Desk.
Large-format historical Sanborn maps, primarily of Brooklyn, are available in the first-floor reference room. Because of their size, weight, and fragility, they cannot be photocopied or scanned, but patrons are welcome to use digital cameras.
