Hoover Tower in the context of "Hoover Institution Library and Archives"

The Hoover Institution (officially The Hoover Institution on War, Revolution, and Peace and formerly The Hoover Institute and Library on War, Revolution, and Peace) is an American public policy think tank which promotes personal and economic liberty, free enterprise, and limited government. While the institution is formally a unit of Stanford University, it maintains an independent board of overseers and relies on its own income and donations. It is widely described as conservative, although its directors have contested the idea that it is partisan.

The institution began in 1919 as a library founded by Stanford alumnus Herbert Hoover prior to his presidency in order to house his archives gathered during World War I. The well-known Hoover Tower was built to house the archives, then known as the Hoover War Collection (now the Hoover Institution Library and Archives), and contained material related to World War I, World War II, and other global events. The collection was renamed and transformed into a research institution ("think tank") during the mid-20th century. Its mission, as described by Herbert Hoover in 1959, is "to recall the voice of experience against the making of war, and by the study of these records and their publication, to recall man's endeavors to make and preserve peace, and to sustain for America the safeguards of the American way of life."
