A major new work, a hybrid of history, journalism, and memoir, about the modern Freedom of Information Act - FOIA - and the horrifying, decades-old government misdeeds that it is unable to demystify, from one of America's most celebrated writers.

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, withheld 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.

In his lucid and unassuming style, Baker assembles what he learns, piece by piece, about Project Baseless, a crash Pentagon program begun in the early '50s that aimed to achieve "an Air Force-wide combat capability in biological and chemical warfare at the earliest possible date". Along the way, he unearths stories of balloons carrying crop disease, leaflet bombs filled with feathers, suicidal scientists, leaky centrifuges, paranoid political-warfare tacticians, insane experiments on animals and humans, weaponized ticks, ferocious propaganda battles with China, and cover and deception plans meant to trick the Kremlin into ramping up its germ-warfare program. At the same time, Baker tells the stories of the heroic journalists and lawyers who have devoted their energies to wresting documentary evidence from government repositories, and he shares anecdotes from his daily life in Maine feeding his dogs and watching the morning light gather on the horizon. The result is an astonishing and utterly disarming story about waiting, bureaucracy, the horrors of war, and, above all, the cruel secrets that the United States government seems determined to keep forever from its citizens.
