It is our pleasure to introduce to the readers of Advances in Psychosomatic Medicine: I, the authors of 88 papers presented at the VIth World Congress of the International College of Psychosomatic Medicine in Montreal, September 13-18, 1981. These papers are re­ presentative of more than 700 presentations and discussions that occurred in the course of lectures, symposia, panels and workshops. Adam J. Krakowski, M.D., primary editor of this volume, together with Chase P. Kimball, M.D., GUnsel Koptagel-Ila1, M.D. and Hellmuth Freyberger, M.D. are responsible for the solicitation and final editing of the papers included in this volume. Most of the plenary papers presented at the Congress and subsequently received for pub­ lication are in preparation for a volume to be issued by S. Karger, Basel, Switzerland, as a special number edited by us with the assistance of Drs. Freyberger and Koptagel-Ilal. The papers included in this volume represent the main substance of the Congress. The editors regret that a number of presentations were either re­ ceived too late or in insufficient form to allow for publication at this time. A number of other papers presented at the Congress have been released for publication in the Journal of Psychosomatic Research, the Psychiatric Journal of the University of Ottawa, General Hospital Psychiatry, Psychosomatics and other journals.
