^* Similar lists have been printed in the Review annually since 1921, except for 1915–19, 1921 and 1923–24; full citations are given in the 1955 list, XLIX, 792.

Items which appeared in the September, 1959, list and which are still in preparation without change are not repeated in this listing. The present listing contains only additions, changes and deletions. Additions are those items which were reported in preparation for the first time; changes are those items which have had a change in name, title, or classification; and deletions are those items which are no longer in preparation.

This year, for the first time, this compilation includes listings for the Canadian universities offering doctoral degrees in political science; and, to enhance the coverage and usefulness of the extension, the Canadian listings have been carried back to 1951.

The classifications this year have been changed as follows: the category of “Political Philosophy and Psychology” has been modified to “Political Philosophy, Theory and Methodology”; the category of “Canadian Government and Politics” has been inserted to follow “American State and Local Government and Politics”; and the category of “Public Administration in the United States” has been broadened to “Public Administration.”

The lists printed in the Review are based on information from departments giving graduate instruction in political science; to avoid misunderstandings, entries are not accepted from individual candidates for degrees. The subject matter classification of an entry by the department concerned, if given, is followed. Each entry is listed under one classification only.

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 September issue, 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 (1952, 1955, 1958); and “Doctoral Dissertations in Sociology,” in the July issue of the American Journal of Sociology. Consult also the “External Research List,” published by the Office of Intelligence Research, Department of State, in April and October of 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 Hannan, “Doctoral Dissertations Accepted by American Universities, 1954–55,” the twenty-second of a series beginning in 1933–34, compiled for the Association of Research Libraries and merged into Dissertation Abstracts. 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.
