deaccession

n. the process by which an archives, museum, or library permanently removes accessioned materials from its holdings v. to remove archival resources from intellectual and physical custody

Notes

Materials may be deaccessioned because the repository has changed its collections policy and the material is no longer within its scope. Materials may be deaccessioned because they have been reappraised and found to be no longer suitable for continued inclusion in the holdings. Materials that are badly damaged and beyond repair may be deaccessioned. Deaccessioned material may be offered back to its donor, offered to another institution, or destroyed.
