THIS REPORT COVERS A REVIEW OF THE LITERATURE ON THE DIAL ACCESS INFORMATION SYSTEMS (DAIRS), USED FOR RETRIEVING AND TRANSMITTING AUDIO AND/OR VISUAL INSTRUCTIONAL MATERIALS TO CARRELS OR CLASSROOMS ELECTRONICALLY. AFTER FORMULATING A WORKING DEFINITION OF THE SUBJECT, A CLASSIFICATION SYSTEM AND SPECIFIC SUBJECT HEADINGS FOR USE IN THE SEARCH WERE DEVELOPED, AND WRITTEN DOCUMENTS ON THE SYSTEM'S TECHNICAL AND INSTRUCTIONAL ASPECTS WERE SURVEYED. IT WAS FOUND THAT THERE IS A PAUCITY OF LITERATURE ON THE SUBJECT, INDICATING THE RECENT, RAPID EMERGENCE OF DAIRS. BECAUSE OF THE GROWING POPULARITY OF DIAL ACCESS SYSTEMS, THE NEED FOR RESEARCH AND EVALUATIVE STUDIES IN BECOMING INCREASINGLY IMPORTANT. THE LITERATURE SEARCH ALSO SHOWED THAT SOME EDUCATORS SEE A MAJOR TECHNOLOGICAL REVOLUTION IN THE EDUCATIONAL FIELD, AND THERE IS A TREND FOR DAIRS TO BE USED IN DEPARTMENTS OUTSIDE THE FOREIGN LANGUAGE LABORATORY, FOR WHICH IT WAS ORIGINALLY INSTALLED. IN THE FUTURE, INFORMATION DERIVED FROM THE CONTINUED SURVEY OF THE LITERATURE AND DIAL ACCESS SYSTEMS IN OPERATION, TOGETHER WITH AN ANALYSIS OF USERS' EXPERIENCES OBTAINED FROM ON-SITE VISITS, WILL BE COMPILED IN A GUIDELINES HANDBOOK FOR EDUCATORS. A 45 ITEM BIBLIOGRAPHY AND GLOSSARY ARE INCLUDED, AND APPENDIXES LIST SOURCES USED IN REVIEWING THE LITERATURE, THE DAIRS PROJECT INFORMATION CLASSIFICATION, THE SUBJECT HEADINS USED, AN EQUIPMENT SURVEY, AND TITLES OF PERIODICALS THAT GIVE INFORMATION ON DAIRS.
