If you’ve ever wanted to know how presidential libraries operate, now’s your chance. According to Dr. Jay Hawkes, presidential libraries are “some of the most important and unique libraries in the country.” The tradition began with FDR, who donated all of his personal and presidential papers to the federal government in 1939. In 1955, Congress passed the Presidential Libraries Act, establishing a system of libraries. And the Presidential Records Act of 1978 deemed all presidential records the property of the federal government. (via Rare Books News)
