This is subtitled ""The Negroes, Puerto Ricans, Jews, Italians, and Irish of New York City"". The ethnic groups of America's most heterogeneous city have been exhaustively studied from all angles, but usually separately, and almost always only so far as their second generations; thus this authoritative yet extremely readable volume has a very special worth. One by one, these authors have taken the five distinctive groups which together are preponderantly responsible for New York's complex image, and have examined their occupational, religious, political, communal, and almost all other classifiable aspects, from the time of their arrival until the present. They have attempted to speak in terms of neither ""blame nor praise"" and to ""view this entire fascinating spectacle of ethnic variety...and to consider what it means"". In such a neglected and immensely complicated subject, judgments which amount to little more than informed guesswork are inevitably frequent, yet the result here is one which should more than satisfy both the sociologist and the general reader.
