Built over the drained Croton reservoir, with seven floors of stacks under Bryant Park carrying the reading room above. Free and open to anyone from the first day, which was Carnegie's condition. Ghostbusters opens in these stacks, with the ghost quietly reshelving before it turns and roars, and the marble lions out front.
That was 1 of the hidden places.
Location: documented spot
