This paper concerns an experiment in teaching a graduate seminar on Information Retrieval using telediscussion techniques. Outstanding persons from Project INTREX, MEDLARS, Chemical Abstracts, the University of Georgia, the SUNY biomedical Network, AEC, NASA, and DDC gave hour-long telelectures. A Conference Telephone Set was used with success. Student diaries and an observer provided part of the background material for this paper. Recommendations include suggestions that the course be given once a week in two and one-half hour sections, with discussion of the telelecture both preceding and following the presentations; that alternate weeks be devoted to classroom lectures on theory; and that there be an exchange of personal information between the speaker and the students before the lecture.
