While I cannot answer your question myself, I may be able to refer you to someone who can. Dr. Stephen Bitgood is a very prolific member of the Visitor Studies Association and the Center for Social Design. He has been most helpful to me in the past and will no doubt be able to answer your questions. I do not have an email address but his postal address is as follows: Dr. Stephen Bitgood Vistior Studies Association P.O. Box 1111 Jacksonville, AL 36265 (205)782-5640 FAX: 205-782-5640 Hope that this helps somewhat. Patricia Kirkland University of Nebraska Dept of Museum Studies (graduate student) [log in to unmask]
