September 2, 1986 Dear Dr. Koop: We wanted to write to express our positive feelings about our involvement with the workshop on pornography. It was an educational process for both of us. We quickly learned a great deal about a foreign area of research and received a valuable exposure to the policy process. Also, it was a pleasure to work with you and Ted Cron. We appreciated the amount of independence given to us and the cooperation we received in meeting the August 1 deadline. Thanks for the opportunity to take part in what we hope was a positive effort by the Public Health Service. If we can be of help in the future, please let us know. Sincerely, Edward P. Mulvey, Ph.D. Jeffrey J. Haugaard, M.A.
