I've been skimming around in the online volumes from the hearings before the Subcommittee to Investigate the Administration of the Internal Security Act and Other Internal Security Laws of the Committee on the Judiciary, United States Senate, Eighty-second Congress, first-[second] session (a.k.a., the McCarran hearings on the Institute of Pacific Relations). George H. Kerr shows up in there, in the form of correspondence from 1942 between Kerr and William L. Holland of the IPR. They're discussing Andrew Grajdanzev's IPR-sponsored book, Formosa Today. Go to p. 393.
