From SF State U. News:
The J. Paul Leonard Library closed in 2008 for renovations to expand and seismically upgrade the building. Limited library services began operating in March 2012 and the Library will be fully operational in fall 2012.
Services now available in the Library include 12 group study rooms in the Study Commons area, which includes computers and quiet study space, the Book Pickup/Checkout Desk and some open stacks.
The building is also home the the Sutro Library, Labor Archives and Research Center, and Academic Technology.
The new library has 34% more total space; 50% more seating; 50% more group study areas; 50% more collection capacity, both in open stacks and a high-density automated retrieval system; and 100% more computers.
