Items which appeared in the September, 1950, list are in general classified under the same headings in the present list, and new items have been assimilated to the 1950 classification as far as possible. In cases where classification of an item has been suggested by the institution concerned, the suggestion has been followed. Each item is listed under one classification only. Names starred are merely carried over from the 1950 list, no more recent data having been received.

This year for the first time there is appended a list of those dissertations which have been reported to the Review as completed since the last listing.

The lists printed in the Review are based on information from departments giving graduate instruction in political science. Often dissertations are in progress in departments of economics, history, sociology, etc., which overlap or supplement dissertations in preparation in political science. Attention is called especially to the following lists: “Current Research Projects in Public Administration” (reported to Public Administration Service), the most recent edition of which appeared early in 1951; “Doctoral Dissertations in Political Economy in Progress in American Colleges and Universities,” in the American Economic Review; “List of Doctoral Dissertations in History Now in Progress,” formerly published by the Division of Historical Research, Carnegie Institution of Washington, but since the 1938 issue as a supplement of the American Historical Review; and “Higher Degrees in Sociology,” in the American Journal of Sociology. Usually one list is published each year. These are in addition to the “List of American Doctoral Dissertations Printed in 1938,” the most recent of an annual series published by the Library of Congress; and Arnold H. Trotier and Marian Harman, “Doctoral Dissertations Accepted by American Universities, 1949–1950,” the seventeenth of a series beginning in 1933–34, compiled for the Association of Research Libraries.
