Why is the entirety of Columbia University labeled as 1901? Low Library was built in 1895 [1], and a number of the buildings on campus date from when the area was a mental asylum [2].
It seems to be treating all of the Morningside campus as one building with the address 530 W 120th St, built in 1901. But that address corresponds to CEPSR, which was built in the 1990s. :/
