The Tokyo War Crimes Trials are on par with the Nuremberg trials for their influence on international law. The importance of the "historical record of events leading up to, and including the trials" has resulted in vast collections of documents. This website from Harvard Law's library contains the papers, letters, and photographs of Joseph Berry Keenan, the chief prosecutor of the Tokyo trials, chosen by President Harry Truman. The website offers finding aid to the collection, which can be quickly accessed by clicking on "Joseph Berry Keenan finding aid in OASIS". The Keenan papers, especially the letters to him, provide a glimpse into all those who had their own particular interest in the trial, including senators, The New York Times, and other lawyers. Most are typed, as this was required from a chief prosecutor, so from a practical standpoint, they are very easy to read.
