The book opens with a lengthy introduction by the editors to the history of the Civilian Public Service camps during the 1940s that came to be known simply as CPS camps. The diary begins November 1, 1944, a few months after John D. Burkholder started his service on July 4th at Camp 45. The diary ends abruptly on May 1, 1946. I cannot find exactly when his time of service ended but the editor reports that the camp closed at the end of June of the same year. [First paragraph.]
