* Similar lists have been printed in the Review annually since 1911, except for 1915–19, 1921 and 1923–24; full citations are given in the 1955 list, XLIX, 792.

Items which appeared in the September, 1956, 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 title or have been completed since the 1956 listing—in which case, the item is followed by the notation “(Completed)” and can also be found in the “Dissertations Completed Since the Last Listing” section; deletions are those items which are no longer in preparation.

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 with the exception of those items listed under “Changes” and marked “(Completed)” which are also listed in Part II of the present 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 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, 1949 and 1952); 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.
