Minneapolis Central Library

Minneapolis Central Library, a library in downtown Minneapolis, Minnesota, United States, is the largest library of the Hennepin County Library public library system. It bills itself as having "the third largest per capita public library collection of any major city in America with a collection of more than 2.4 million items—including books, DVDs, music, government documents." The 353,000-square-foot building at 300 Nicollet Mall with two levels of underground parking was designed by César Pelli and opened on May 20, 2006. It has over 300 computers for use by the public, an 8,140-square-foot atrium, an 18,560-square-foot green roof planted with low-growing ground cover designed to "be sun- and drought-resistant", and a host of energy-efficiency measures.
