This compilation was conceived as a means of encouraging research in Hungarian history. It is limited to dissertations completed for academic degrees in Austria, Canada, France, Germany, the United Kingdom, and the United States. Unless otherwise noted, all entries refer to Ph. D. dissertations. In preparing the European entries, no attempt was made to distinguish between the degrees of Doctorat de Spécialité, Doctorat d'État, and Doctorat de l'Université, on the one hand, or Dissertationen and Habilitationsschriften, on the other. The chronological limits of the compilation extend from 1920 to 1972.
