Directions to the Oskar Diethelm Library

525 East 68th St., New York NY 10065 (Baker Tower, Room F-1212)

To get to the Library and Institute, walk east along 68th Street to New York Presbyterian Hospital’s main entrance, located at 525 East 68th Street, just beyond York Avenue. Enter here, and once you have passed Security (where you will be required to present some form of picture identification), walk straight ahead to the Information Desk. When you arrive at the Information Desk, make a left and go through the open doorway directly ahead of you. On your right, directly inside that doorway, you will find a bank of elevators. Take these elevators to the twelfth floor. When exiting the elevator, make two sharp right turns. This will bring you to the Oskar Diethelm Library’s Reading Room (F-1212) and the main offices of the Institute of Psychiatry. If you require any assistance, please call Nicole Topich at 212-746-3728.
