November 16 - We went to the New York Public Library. It's probably my favorite building in the city - so beautiful inside. My favorite is the Rose Main Reading Room. Gorgeous!
They used to use a pneumatic tube system to send paper slips requesting books down seven floors of books deep underground. The request is received, the book located, and it is sent up on a "ferris wheel of books." Cool, right? They just recently stopped using the system.
Side note, I found out that in 1897 they used a pneumatic system to deliver mail between post offices all over Manhattan & Brooklyn. In the height of it's operation, "the pipes ran between 4 to 12 feet underground, and in some places the tubes ran along the subway tunnels of the 4, 5 and 6 lines. At the height of its operation it carried around 95,000 letters a day, or 1/3 of all the mail being routed throughout New York city."
Anyways, here's the zip tube at the top:
we stopped in to the children's book exhibit, one of our favorites!
