The Herbert Hoover Presidential Library and Museum in West Branch, Iowa, was the fourth of the presidential libraries now managed by the National Archives and Records Administration. It was dedicated in 1962 and expanded to 44,500 square feet thirty years later. Inside is the 90 year story of how a great man helped millions around the word with his relief efforts and assisted millions more in the U.S. during the Great Depression years of 1929 through 1933.
