Series III of the investigations of the Committee of the Reichstag, one of the most important collections of source material on the history of the war. The committee took testimony on all questions of violations of international law and now publishes all the very extensive evidence, the only problem of major importance that is omitted being that of the violation of Belgian neutrality, which is reserved for a later date. The decisions of the experts may be questioned on some points and did, in fact, lead to majority and minority reports, but apart from all this the value of the source material presented cannot be over-emphasized.
