Eight years ago, while investigating the possibility that the United States had used biological weapons in the Korean War, Nicholson Baker requested a series of Air Force documents from the early 1950s under the provisions of the Freedom of Information Act. Years went by, and he got no response. Rather than wait forever, Baker set out to keep a personal journal of what it feels like to try to write about major historical events in a world of pervasive redactions, witheld records, and glacially slow governmental responses. The result is one of the most original and daring works of nonfiction in recent memory, a singular and mesmerizing narrative that tunnels into the history of some of the darkest and most shameful plans and projects of the CIA, the Air Force, and the presidencies of Harry Truman and Dwight Eisenhower.
