Befits the endeavors of BP.,
This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
The title says it all. The contributions made by the people who where there, make it a must for anyone slightly interested in Bletchley Park. The insight into the life and workings of the code breakers, makes this new edition a source for reference. Seeing as the majority of the written records where destroyed, exept for what GCHQ still retain, and the fact that it is 70 years ago, we need these recollections.
