Where is the lost and found?
All lost articles are turned over to the library security officer stationed at the main entrance immediately upon their discovery. Items left in the library classrooms are taken to the security desk in the lobby of the first floor. Lost IDs are given to security, which forwards them to the ID office on the first floor. Security refers other lost items to the Lost and Found office on the first floor of 17 Lexington Avenue (23rd St.), which is open from 9 a.m. – 4 p.m., Monday – Friday.
