THE University of Chicago’s new Joe and Rika Mansueto Library is a futuristic bubble of a building with nary a stack in site. Many of its nearly one million items — special collections, journals, dissertations, documents — can be accessed online.

But while many academic libraries are digitizing and moving holdings off site, Manseuto is the largest and latest (of about two dozen libraries) to add automated storage and retrieval systems. Volumes are housed in solid steel cases about 50 feet below ground. Should someone want to actually touch the real thing, books are delivered through a labyrinthine system of cranes and elevators. Picture the door-sorting machine from Pixar’s “Monsters Inc.”

The $81 million Mansueto (Mr. Mansueto founded Morningstar) has capacity for 3.5 million volumes, freeing space in the cramped stacks that students browse at the main library.

And in apt example of the tug and pull on today’s library, Mansueto has a lab for both digitization and conservation. It mends paper and rebinds the university’s books — some of them papyrus — when it’s not cleaning and preparing materials for scanning, some for its partner, Google Books.
