So much new material has gone into this revision that it could be legitimately sold as a new book. Even the historical background on minorities receives new focus, while the impact of war has precipitated more into these years since 1943 than in the whole period between the Civil War and World War II. The long introduction aims to point the questions this revision seeks to answer:- how far have we gone, in what direction, what of the future? Special emphasis (not given in the original book) to the Negro problem as ""America's most persistent and pernicious domestic, social problem"" shows new racial frontiers, ideological ferment growing out of migratory factors, urbanization, industrialization, the Civic Unity Councils, the FEPC, and so on. There have been substantial gains in these years, but the end result marks the beginning of a new crisis in class relations. The body of the book (covering other minority groups) has additional material within the text and at the chapter ends, as would be inevitable with result of the war on the status of Orientals, Hawaiians, Filipinos, and- the Jews, with the influx of the dispossessed from Europe. Timely and important as a current issue.
