INDEXED ARE 991 PERIODICALS, REPORTS, BOOKS, AND OTHER PUBLICATIONS CONTAINING INFORMATION PERTINENT TO OUTDOOR RECREATION WHICH WERE RECEIVED BY THE DEPARTMENT OF THE INTERIOR LIBRARY DURING 1966. THIS SHOULD NOT BE MISTAKEN FOR A COMPREHENSIVE BIBLIOGRAPHY OF OUTDOOR RECREATION LITERATURE BECAUSE NOT ALL PUBLICATIONS RECEIVED BY THE DEPARTMENT OF THE INTERIOR LIBRARY HAVE BEEN EXAMINED FOR CONTENT RELATIVE TO OUTDOOR RECREATION. THE FOUR CATEGORIES USED IN CLASSIFYING DOCUMENTS ARE (1) OUTDOOR RECREATION RESOURCES, (2) ADMINISTRATION OF RESOURCES AND PROGRAMS, (3) RECREATION USERS, DEMAND AND VALUES, AND (4) RESEARCH. INFORMATION FOR EACH PUBLICATION INCLUDES A BIBLIOGRAPHIC CITATION AND A BRIEF ABSTRACT. THE MATERIAL IS INDEXED IN THREE FORMS. A SUBJECT INDEX IDENTIFIES CITATIONS BY THE USE OF NEARLY 1,000 KEY WORDS OR DESCRIPTORS RELATED TO OUTDOOR EDUCATION. A NAME INDEX DESIGNATES CITATIONS BY AUTHOR, EDITOR, INDIVIDUALS AND ASSOCIATIONS DISCUSSED IN THE ARTICLE, OR OTHER PROPER NAMES EXCEPT GEOGRAPHIC LOCATIONS. A GEOGRAPHIC INDEX IDENTIFIES CITATIONS BY COUNTRIES, GEOGRAPHIC REGION, STATES, COUNTIES, CITIES, AND RIVERS, AS WELL AS BY PROPER NAMES OF UNITS ADMINISTERED BY FEDERAL AND STATE AGENCIES WHICH APPEAR IN THE DOCUMENT. APPENDICES INCLUDE (1) LISTINGS OF THE PERIODICALS SCANNED IN DEVELOPING THE INDEX, AND (2) A LISTING OF SERIAL PUBLICATIONS. THIS DOCUMENT IS ALSO AVAILABLE FOR $0.75 FROM SUPERINTENDENT OF DOCUMENTS, GOVERNMENT PRINTING OFFICE, WASHINGTON, D.C. 20402. (DS)
