Natural history collections in museums around the world represent the results of centuries of collecting and systematic research. The value of these collections is poorly understood by the public and, more importantly, by the politicians responsible for the funding of most museums. Funding for the sciences in museums in general, and for natural history museums in particular, is significantly lower than that granted to the arts. As a result, natural history collections, even in large national institutions, are threatened with deterioration because of poor curation and inadequate storage conditions. Research and development of better methods for the preparation and preservation of natural history materials in museums is necessary in order to preserve our heritage of collections and to make the most efficient use of diminishing funds. Strategies for improving care of natural history collections include development of improved curation procedures, increased public awareness of the value of the collections, and training programs for specialists in the conservation and collection management of natural history materials.
