Best book on Cold War spy satellites in space,

William E. Burrows
This is still the only really great book on overhead reconnaissance, and I have been surprised and disappointed to see it overlooked by the mainstream intelligence academics. Contains useful early history on why we got into technical collection (our human spies kept getting killed on arrival as we took the easy route of recruiting from émigré organizations already penetrated by the KGB and GRU). Ends with a passing reference to commercial imagery, a topic that merits its own book.
