Consider this illustrative situation: An heir inherits a collection and an archive on different terms. Physical custody, copyright, family access and cultural meaning may belong to different people; a single inventory will not answer all four questions.
A family has inherited records, collections, rights or responsibilities that were never organised for the next steward. The visible request may be a book, move, announcement, licence, archive, event or venture. The real question is what becomes harder to reverse once the first commitment is made.
Value, provenance and meaning can be lost when custody changes before ownership, context and access are understood.
