The Minneapolis Public Library (MPL) was a library system that served the residents of Minneapolis, Minnesota in the United States. It was founded in 1885 with the establishment of the Minneapolis Library Board by an amendment to the Minneapolis City Charter. Lumber baron and philanthropist T. B. Walker and other city leaders such as Thomas Lowry were members of the first library board. In 2008, after some financial difficulties, the library was merged into the Hennepin County Library system. At the time of its merger, the library included Central Library in downtown Minneapolis and fourteen branch libraries. Its collection numbered about 3.1 million items with about 2.2 million of these housed in the central library. Central Library The predecessor of Minneapolis's public library was a private library called the Minneapolis Athenæum. It was organized by Minneapolis businessmen in 1859 as a subscription library, and its shares were traded on the local stock market. After T. B. Walker moved to Minneapolis he bought shares in the Athenæum and gave away memberships to it, promoting the idea of a free public library for the city. Other stock holders raised objections, but the technique worked and soon the city financed a free library for the public with a one mill property tax. When the Minneapolis Public Library was established in 1885 the Athenæum became a partner of it and still exists as a separate nonprofit organization sharing space with the library. Three central libraries have been built in Minneapolis, each replacing the last with a bigger and more up-to-date building. The first opened in 1889, the second in 1961 and the third and current building in 2006. On November 7, 2000, Minneapolis voters approved a $140 million package to improve library services, including funding a new Central Library building. The building was designed by Cesar Pelli, along with the Minneapolis firm Architectural Alliance, It opened to the public on May 20, 2006. At a cost of $250 per square foot, the library features a host of energy-efficient measures, including a roof garden and substantial daylight. While the building was under construction, most services were provided at the interim Central Library Marquette location, on two floors in Marquette Plaza (formerly the Federal Reserve Bank of Minneapolis). Cost of providing an interim site while the old library was demolished and rebuilt exceeded $10 million. Until the 2002 closure and demolition of the old central library,
