HOW IT WORKS:
1. Book is requested using online catalog.
2. Five cranes run along parallel tracks; one is activated and locates materials using bar codes.
3. Crane removes appropriate container — one of nearly 24,000, each weighing up to 200 pounds — and transports it to an elevator, which lifts it to the resource desk.
4. Human retrieves and scans book’s bar code, initiating e-mail notification to student.
Time elapsed: Five minutes or less.
