Dear Zoo person, Actually your request is not so unusual. Zoos are included in the related- museum institutions that are part of the ICOM , AAM, CMA etc., etc., definitions of museums although we often forget it. About three years ago one, one of our graduate students completed her research paper on this very subject. She did a visitor study at the Metro Toronto Zoo evaluating visitor responses to elements of zoo presentation and issues of environment. Her name is Robin Whittal and she is now Head of Educational Programming at the Sacramento Zoo , that is in California. Robin has an extensive background in natural science programming as she worked for some time at the Vancouver Aquarium and then was in Programs at the Royal Ontario Museum for about two years. You can try to phone her at the Sacramento Zoo. We can also provide a copy of her research paper for a cost. So do let me know what you wish to do. Yours truly, Lynne Teather, Professor, "be-mused, bothered and bewildered" Museum Studies Program, University of Toronto, Toronto, Ontario E-mail: [log in to unmask] Phone: 416-9788822
