Public institutions offered greater security for collections than individual families because they functioned as corporate units, which provided a more reliable guarantee of succession for the items in their care. While private collectors were often concerned with the continuity of their holdings, they frequently lacked a mechanism to ensure that their collections would remain intact after they were gone.1

By transferring collections into the public domain, institutions could ensure that knowledge and cultural heritage were preserved for the long term. This commitment to permanence is often codified in legislation, which may declare museum collections inalienable, meaning they cannot be easily sold or dispersed. Unlike the family unit, which is subject to the uncertainties of inheritance and changing personal circumstances, a museum operates as a stable entity dedicated to the ongoing conservation and study of its holdings.123
