The most basic task of any museum must be the protection of works of cultural significance entrusted to its care for the edification and pleasure of future generations. This imperative rightfully takes precedence over acquisition, interpretation, outreach, or any number of other activities now believed to be crucial to the survival of our great art repositories. Sometimes a museum gains its holdings with much strategic forethought, and at other times serendipitously, as when a long-coveted neighbor’s plot suddenly becomes available. Yet the moral responsibility remains the same.
