"The Pacific War Papers is an annotated collection of extremely rare Japanese primary-source documents that provides an invaluable resource for historians, students, and others with a deep interest in World War II. These naval and diplomatic documents come from the collection of the late Gordon Prange, the eminent scholar of Pearl Harbor, who obtained them from Japanese naval leaders while working for the Military History Section of the American forces that occupied Japan."-- From the book jacket.
