The primary purpose for the preparation of this selected bibliography was to support the research endeavors of the CIC-AID Rural Development Research Project. Periodical publication coverage has included the period of 1955-1965, and, has excluded all foreign language materials. Over 90% of the articles in this volume have been abstracted, and about 900 of the most relevant have been reviewed for the purpose of extracting the most important concepts. The periodicals appear in alphabetical order and chronologically under each journal heading. Under the detailed search system, articles are identified by an arabic numeral and a letter. Then each article and concept is labeled with one or more index numbers. These number codes are listed in six major categories with subtopics: geographical area and country (Africa, Asia, South America, Caribbean, Oceania, Europe, North America), economic development, agricultural development, social change, education development, and political development. A separate system using the same index numbers has been developed to facilitate the search for concepts independently of the search for abstracts.
