This bibliography of 2,170 theses and dissertations and 865 other studies updates the 1970 "Bibliography of Theses and Dissertations in Recreation, Parks, Camping, and Outdoor Education," published by the National Recreation and Park Association, and integrates the 1963 "Bibliography of Research" issued by the American Camping Association. The subject scope has been expanded to include adventure sports/activities, environmental education, interpretive services, and outdoor recreation users and programming. About half of the theses and dissertations were completed in the 1970s; 43 were completed prior to 1934. The theses and dissertations represent work done at 221 different institutions with 30 institutions having 20 or more listings. Theses and dissertations are usually available from the sponsoring institution. When another source is known it is given. In the case of documents available from the ERIC Document Reproduction Service or Xerox University Microfilms an order number is included in the citation. (SV)
