Anotations

Scope note:

Individual objects or works. Most works in museums are cataloged as items. A stand-alone architectural work should generally be cataloged as an item. An item may be composed of multiple parts or components, and it may be desirable to catalog the parts separately, linking the records for the components to the record for the whole. An item differs from a component in that the component cannot stand alone as an independent work.
