A carefully selected bibliography of some 7,000 books published in the post-war period, and covering the whole field of international relations -- current history, politics, economics, finance, international law and diplomacy, as well as related subjects such as race conflicts, population and immigration problems, colonial problems, propaganda, modern warfare and disarmament. A section of 75 pages is devoted to the World War, covering the diplomatic background as well as the conduct of the war on land, sea and in the air, economic aspects, and the peace negotiations. Economic subjects are given special attention, and a section 25 pages in length describes books dealing with the theory, origins and work of the League of Nations. The later chapters of the book take up the world, region by region and country by country. The section on Russia is particularly complete. In all, the entries are classified under about 300 headings. Each entry carries a sentence or two of description, designed to indicate the nature of the book and if possible the qualifications of the author. The work should be of value in libraries, universities, newspaper offices, banks, and indeed wherever there is study, research or writing on international affairs.
