I'm partial to the Elmer L. Anderson library and the Minnesota Library Access Center located at my alma mater, the University of Minnesota. It might not be quite as large as Harvard's store, but instead being located in an warehouse, it's located in two lime stone caverns carved into the bluffs above the river. The Andersen Library has been characterized as "geology-friendly;" and indeed, the geology of the site is an integral part of the underground structure. Behind the concrete portal, two enormous caverns, each two stories high and the length of two football fields, lie below a 30 foot layer of limestone plus an additional 30 feet of topsoil, clay and gravel. The solid limestone serves both as the structural roof of the caverns and the foundation for the Andersen Library building above.
