University of Chicago's Mansueto Library suffers power outage

May 30, 2011 The 's Joe and Rika Mansueto Library was shut down by a power outage for a short time on Saturday, preventing library personnel from providing full services to its patrons.

The 81 million library, which opened May 16, includes a 180-seat reading room under a 691-panel glass dome. Five stories underground, a system of five cranes retrieves books sorted into bins, carrying a maximum of about 3.5 million volumes. As of 3:50 p.m., the automated storage and retrieval system, along with staff computers at the circulation desk, were shut down, preventing patrons from retrieving materials stored underground.

The glass ceiling normally allows enough natural light to pass, but rain clouds in the area darkened the room. Patrons began to flip light switches in front of their seats, but to no avail, and a circulation clerk announced that there had been a power outage. Some patrons then moved to the adjacent, which still had power. Power was still running along the corridor linking Mansueto and Regenstein Libraries, along with the nearby restrooms and Special Collections Research Center.

An electrician arrived at the building at around 3:50 p.m., and power had been restored by 5:45 p.m.
