Herbert Hoover National Historic Site (National Historic Site) · Restricted Access
In recent years, the Library and Museum has been transformed into a nationally recognized center for the study of twentieth-century history and the American presidency. Simultaneously, the Library had redoubled efforts to locate and collect documentation pertaining to the Hoover Era. In addition to the papers of Herbert Hoover, the manuscript holdings include those of Lewis Strauss, Gerald P. Nye, Felix Morley, Clark Mollenhoff, Robert E. Wood, Westbrook Pegler, and Laura Ingalls Wilder, among others. More than 150 collections make the Library an important center for the study of conservative journalistic thought, agricultural economics, famine relief, atomic energy, and governmental reorganization. Ten thousand square feet are devoted to seven museum galleries telling Hoover's fifty years of public service.
