The stacks under the library can hold 4 million books (the actual number in storage is lower, though no one is quite sure), which are delivered to the reading room by 950 feet of miniature rail running at 75 feet per minute. But the real gem of the library, in Lannon’s view, is the stuff that you can find only in boxes like the ones now strewn across the table. … These collections aren’t digitized.
Lannon said that Google had changed the way people sought information. “They only want information based on the information they think they want,” he said. As a rule, he said, archivists at the library should give you the box you’ve asked for — but also suggest another box. There are fewer opportunities, now, to stumble into a world you don’t already know. “It’s important to look outside of your own existence.”
