| Sumario: | The article features the DIALOG, an interactive information retrieval system which allows the operator to formulate search questions via a video/keyboard display terminal, used by the Council for Exceptional Children Information Center in the U.S. The DIALOG looks like a television set with an attached typewriter keyboard and teletype writer. It has the capacity to search three major files of information available to users including "Exceptional Child Education Abstracts," "Research in Education," and "Current Index to Journals in Education."
