Developmental change and the related problems of modernization have attracted the attention of scholars in many discipliness. In this bibliography -- derived and expanded from an earlier compilation by Mr. Spitz and Edward Weidner -- the author orders and annotates nearly 2,500 articles appearing between 1945 and 1969 in 234 journals from 25 countries. Organized by subject and indexed by both author and journal, the citations include studies of social problems, economic factors, political questions, public administration, and international cooperation and assistance. Special emphasis has been given to new and little-known sources. In addition, a selected bibliography of monographs and book-length studies dealing with the modernization of underdeveloped countries and areas is included in the volume.
