Items which appeared in the September, 1953 list are in general classified under the same headings in the present list, and new items have been assimilated to the 1953 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.

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 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,” published annually by the Division of Historical Research of the Carnegie Institution through 1938, and since then by the American Historical Association, as supplements to the American Historical Review (1940 and 1941), as Vol. III of its Annual Report (1941), and as separate publications (1947 and 1949); and “Doctoral Dissertations in Sociology,” in the American Journal of Sociology. Consult also the “External Research List,” published by the Office of Intelligence Research, Department of State. 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, 1952–53,” the twentieth of a series beginning in 1933–34, compiled for the Association of Research Libraries. Consult, for other lists, T. R. Palfrey and H. E. Coleman, Jr., “Guide to Bibliographies of Theses, United States and Canada” (Chicago, American Library Association, 2nd ed., 1940).

Abstracts of some of the theses listed as completed may be found in “Dissertation Abstracts,” published bi-monthly by University Microfilms, Ann Arbor, Michigan.
