Forty years of the major sociological journals—the American Journal of Sociology and the American Sociological Review—are reviewed to evaluate Freud's influence on American sociology. The one hundred seventy-five references are in themselves a gold mine of data for the researcher. But Jones also describes the antifreudian and profreudian attitudes of leading sociologists and the reasons therefor. Noteworthy is the receptiveness of these journals to papers by analysts from the early 1930's on.
