Twenty-five Freaking Miles!

"In 1919, the Hoover Library and Archives began collecting firsthand accounts of historical events and political transformations. Today the library contains close to one million volumes; the archives houses some 60 million documents and 100,000 political posters. These original sources fill twenty-five miles of shelving, but their reach is global. Each year 3,500 researchers from all over the world, as well as nearly every state in the country, visit the library and archives to use their materials on political, economic, and social change in modern times."
