kkleiner writes "The University of Chicago’s new $81 million Joe and Rika Mansueto Library is being referred to as the library of the future. You enter the library and find there are hardly any books, just a large reading room with computers. The library's 3.5 million books are stored inside 35,000 bins stacked within 50 foot tall racks in a massive 5-story chamber underneath the library. When you ask for a book an automated retrieval system involving huge, computer-activated robotic cranes finds the book you want, delivers it to the circulation desk, and eventually puts it back underground when you return it."
