London — The London Sunday Times printed the first excerpts from what it called the secret diaries of Adolf Hitler. The discovery of the 60 handwritten volumes, which include sketches and pictures, was announced by the West German magazine Stern. Among other things, the extracts covered Hitler's criticism of leading Nazis and generals. Some historians have doubted the authenticity of the diaries, which the Times said were discovered in a hayloft cache in East Germany by a journalist. An eminent British expert on Hitler's life urged West Germany to form an international commission of inquiry into the reported discovery of Hitler's diaries. The Times will publish more of the extracts and Stern was due to begin serializing the diaries today.
