This important collection of documents from the files of the Palazzo Chigi for the most part supplements Ciano's "Diaries," either published or yet to appear. To Ciano's minutes of 184 conversations with foreign statesmen between 1936 and April 1942 the editors have added some 40 hitherto unpublished documents and other useful explanatory matter. Though there are few great revelations, much new light is thrown on Italy's tortuous foreign policy, particularly in regard to Germany and Spain.
