Accession Date

Accession date is the date when an object formally entered a collection system and became part of a documented record structure.

It should not be confused with the date an object was made, found, photographed, digitized, or described.

Accession date helps distinguish object history from record history. It supports traceability, revision tracking, and collection management.

  • Check whether the date refers to accession, acquisition, digitization, or record creation.
  • Avoid treating accession date as the object’s creation date.
  • Compare accession date with catalog number and provenance notes.

Ask students to compare “object date,” “accession date,” and “record updated date.” What does each one tell us?

Public sources will be added as this entry is reviewed and expanded.

This entry explains accession date as a documentation field. It does not provide acquisition, transfer, valuation, legal, or collection-intake guidance.
