During the long years of civil strife in China the Nationalist authorities amassed extensive materials on their Communist adversaries. Now stored in government institutions on Taiwan, these materials are an excellent source for the study of the Chinese Communist movement. Among them is the Bureau of Investigation Collection (BIC), which holds over 300,000 volumes of primary documents on the Chinese Communist movement. The purpose of Chinese Communist Materials is, without any attempt at comprehensive listing of the Bureau’s holdings, to give scholars a representative description of the collection, to point out its implications for research, and suggest new areas for research at the Bureau in the fields of political science and history [1, 4].

This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945.

This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945. It traces the all-important genesis and development of the cryptanalytic techniques used to break the main Japanese Navy code (JN-25) and the Japanese Army’s Water Transport Code during WWII. This is the first book to describe, explain and analyze the code breaking techniques developed and used to provide this intelligence, thus closing the sole remaining gap in the published accounts of the Pacific War. The authors also explore the organization of cryptographic teams and issues of security, censorship, and leaks. Correcting gaps in previous research, this book illustrates how Sigint remained crucial to Allied planning throughout the war. It helped direct the advance to the Philippines from New Guinea, the sea battles and the submarine onslaught on merchant shipping. Written by well-known authorities on the history of cryptography and mathematics, Code Breaking in the Pacific is designed for cryptologists, mathematicians and researchers working in communications security. Advanced-level students interested in cryptology, the history of the Pacific War, mathematics or the history of computing will also find this book a valuable resource.
