"Inside there is the deep quiet of protection and near-abandonment. You hear the hum of the lights, turned on as needed; that’s it. There’s a phone to make outgoing calls on the fifth floor. To me the stacks are the most sacred space in the library, yet here nobody’s telling you not to talk. You’re on your own. It’s a situation for adults."
(Ben Ratliff, Grazing in the Stacks of Academe, about Columbia University's Butler Library)
