Reviews

“There is significant explanation of how codes and ciphers were constructed and solved, how the use of mathematics regulated code breaking, and the process of producing and distributing thousands of code books during the war. This volume will be of great interest to faculty and students in this specialized subject area. Summing Up: Recommended. Upper-division undergraduates through researchers and faculty.” (D. K. Blewett, Choice, Vol. 54 (3), November, 2016)
