The purpose of the unclassified bibliographic survey was to update information on the Middle East which appeared in DA PMA 550-2-1, issued in April 1968. The publications included are available in the open holdings of The Army Library, Pentagon. The information appearing in the abstracts is supported by 51 appendixes including 30 maps, of which 24 are in color. The appendixes contain information of military, political, economic, and sociological nature. Materials dealing with Arab nations include both the countries of the Middle East and North Africa (the Maghreb). The organization of the table of contents and the manuscript are reflective of this approach to the subject. The main emphasis, however, is on the countries of the Middle East. Selections were made from several thousand periodical articles, books, studies, and reports, both friendly and unfriendly. No effort has been made to delete or exclude references by reason of their controversial nature.
