##  [Deaccessioning](/deaccessioning-1) 

 Definition

The formal, documented process by which a library, archive, or other collecting institution permanently removes an accessioned item from its institutional collection inventory and determines its disposition (for example: retention off‑site, transfer, donation, sale, recycling, or destruction) according to established policy, legal constraints, and provenance or donor conditions.

 

 

 

 

 

 





## Principle

Principle

Removal from the institutional collection requires explicit policy criteria and a recorded decision so that ownership, provenance, legal obligations, and long‑term stewardship responsibilities are clear.

 

 

 

 

 





## Demonstration

Demonstration

Illustrative scenario: Situation — a circulating monograph is repeatedly duplicated across the catalogue, in poor condition, and falls below retention criteria. Recognition — staff compare the item to the collection policy and donor terms. Action — the item is formally deaccessioned, the catalogue record is updated with disposition notes, and an offer to transfer to a partner institution is documented. Consequence — shelf space and processing resources are freed while an auditable trail preserves provenance and legal compliance.

 

 

 

 

## Misapplication

Misapplication

Treating any physical removal from shelving as deaccessioning without recording disposition or checking donor/license restrictions; the semantic error is conflating informal weeding or temporary removal with formal, permanent transfer of custodial responsibility.

 

 

 

 

 





## Consequence

Consequence

A deaccessioning decision changes legal and custodial status of materials, affects research reproducibility and provenance records, and may obligate the institution to follow donor restrictions, accounting rules, or public trust duties; improper deaccessioning can irreversibly remove unique evidence.

 

 

 

 

## Reversal

Reversal

Exceptions occur where items are subject to explicit donor restrictions, legal holds, cultural repatriation claims, or archival retention mandates that prohibit permanent removal; temporary removal for conservation or digitization is not deaccessioning when accession and ownership remain unchanged.

 

 

 

 

 





## Boundary

Boundary

Clearly within — permanently removing a duplicate accessioned monograph and recording its transfer. Boundary case — an item in poor condition whose donor restrictions are unclear and require legal review before disposition. Clearly outside — temporary relocation for repair or circulating items removed from stacks but still recorded as held by the institution.

 

 

 

 

 





## Semantic Tension

Semantic Tension

Stewardship (preserve completeness and provenance) ↔ Practical Management (free space, reduce cost); the tension requires policy choices that balance research value against operational constraints.

 

 

 

 

 





## Synthesis

Synthesis

Deaccessioning is a governance action, not mere disposal: it formally transfers custodial responsibility and thus must be governed by documented criteria, provenance awareness, and legal or ethical constraints rather than by ad hoc convenience.
