Works that cannot be, or have not yet been, identified as to the object type and other information. Term may be applied to movable works or built works. The term is most often used for works currently known or in collections, but for which the purpose of the work is not known and thus work type is not known. For works known by name in literature or otherwise doscumented, but not firmly associated with the corresponding physical work, use "unidentified named works."
