Ask a Question

The Lionel Pincus and Princess Firyal Map Division is one of the world’s premier map collections in terms of size, scope, unique holdings, diversity and intensity of use. Established in 1898, our holdings include more than 433,000 sheet maps and 20,000 books and atlases published between the 15th and 21st centuries. The collections range from the global to the local scale and support the learning and research needs of a wide variety of users.


In-Person Research

Researchers can access the collections in our splendid reading room (renovated in 2005) by browsing our open shelf reference books, our dictionary catalog or with the guidance of our staff. Most maps and atlases are stored on closed shelves and are typically brought to the reader in less than an hour. A valid library card is required. ( Apply for a card ) Laptops are welcome as our reading room is Wi-Fi enabled and equipped with ample power outlets. There are also six computer workstations with access to Digital Sanborn Maps:1867-1970, Google Earth, and Oasis NYC: community maps of New York City. Reproductions are made at the discretion of the staff and include photocopying and scanning.
