Say goodbye to book stacks and aching backs. The New York Public Library is reopening its stunning Rose Reading Room with a special addition: a whizzing book train that looks like something out of Wallace and Gromit. In the video above, the train’s carriages zoom at every possible angle, as it traverses 11 levels of the library, from an underground storage lair below Bryant Park, to the iconic reading room, beloved of writers like Norman Mailer, E.L. Doctorow, and Isaac Bashevis Singer. $2.6 million well spent.
