Most museums will need to use several distinct numbering sequences within their documentation system.
Numbers provide a code for uniquely identifying objects.
They allow convenient and precise cross-reference between records. The sequences needed and the form they take, will vary slightly from museum to museum, depending on individual needs and past practice. Entry number A number on the entry form which identifies objects until they are either returned to their owner or formally acquired by the museum. A number in the accession register which normally only applies to items formally acquired by the museum. A number on the transfer of title form relating to the transfer of legal title of the object to the museum.
