Each year, thousands of researchers from around the world visit the Hoover Institution Library and Archives to examine their vast store of materials. From the political cartoons of Louis Raemaekers from World War I to the recordings of Radio Free Europe/Radio Liberty (RFE/RL) broadcasts during the cold war to the tapes of William F. Buckley Jr.'s Firing Line television series, more than 5,000 separate collections of historical documents are housed in the library and archives. Each collection plays a vital role in understanding the history of the twentieth and twenty-first centuries.
