Terry Martin, Curator and Chair of Anthropology for the Illinois State Museum (ISM), shared several interesting thoughts with us concerning the implications of placing control over preservation policies at various levels of government or in various private hands. I suggest that these considerations are tied up with the question of what is the value of preservation.
Dr. Martin noted that localities are sometimes more enthusiastic about, or attentive to, local preservation projects than are state agencies. Moreover, state agencies sometimes hobble themselves with bureaucratic restrictions (such as the prohibition on ISM officials using state vehicles to travel to out of state conferences). On the other hand, localities sometimes resist state regulations designed to protect sensitive sites when general principles of preservation conflict with particular local interests (which may be economic as well as cultural). One big example, potentially, is repatriation policy as exemplified by NAGPRA. In such instances, state or national authorities are in a position to establish standards desirable in the long run, which localities might sometimes be tempted to violate if they were free to do so. It is unlikely that any coherent repatriation policy could be maintained by local action alone, and this inability would prevent productive cooperation between, say, Native Americans and preservationists, or other parties with competing interests.
All this applies not only to local government agencies but also, in part at least, to local private agencies. "Friends societies" often provide indispensable political and financial support for cultural site protection. Some private museums, such as Chicago's Field Museum, are among the best in the field. On the other hand, local enthusiasts can sometimes be oriented toward development at the expense of preservation. And museums often suffer when they are part of a university, even a wealthy private university, because other university goals get higher priority than does the perpetual maintenance of collections.
One conclusion I take from this is that there are some values of preservation that are important at the aggregate social level (states, the nation as a whole, the world) but that, at the local level, become under-emphasized collective goods or compete with other, purely local goals.
