As a follow-up of a proposal, launched at the 1984 meeting of ICOM/CC by the coordinator of the working-group Theory and History of Restoration , a small one-day-symposium was organized in the Central Laboratory in Amsterdam under the title Interdisciplinary aspects of conservation and restoration. This meeting was meant to investigate the possibilities for a widening of the interdisciplinary circle concerned with conservation and restoration theoretical problems. The speakers represent the following disciplines: Economics, Operations Research, Social Psychology, Museology, Philosophy, Perception Theory, Aesthetics, Art History, Anthropology, Psychoanalysis. It will be evident from this report that the vistas the various disciplines may open towards a better understanding of the forces that determine our decisions in conservation and restoration were only hinted at. In one day to deal with ten totally different approaches was a bit much, but the general opinion of the participants of this meeting was that each discipline deserved a much broader and deeper involvement, and may then provide most interesting new approaches to areas of concern. -- AATA
