The memory of alerts

A closed alert keeps its value. The archives preserve all alerts published since 2012, about 1,900 (indicative figure), with their outcome: work recovered, returned, withdrawn or still missing.
Current alerts appear in the list of active alerts. The archives complement the database of the Protection section.

Why keep alerts
A stolen work may resurface decades later. Keeping alerts, even old ones, makes it possible to match an object presented today with an earlier disappearance and to document its history.
The archives also serve research: art historians, jurists and criminologists find data there on the evolution of trafficking, its routes and its targets.



What an archived record contains
The record reproduces the text of the original alert and adds the date and reason for closure. When the work has been recovered, a note says so, without detailing the circumstances when proceedings are under way.
Photographs are kept where rights permit. Individuals' personal data are removed on closure, unless the persons concerned agree otherwise.
Archives and provenance verification
For a buyer, consulting the archives is a step of due diligence. An object whose description matches an old alert calls for documented explanations before any transaction.
This check does not remove the need to request a certificate. It works alongside document verification and the certification services.
Rights of access and rectification
The archives are public, but the persons mentioned retain a right of rectification. An owner whose work has been recovered may request that the record be updated or a comment added.
The request is made through the contact form. The Secretariat replies within an indicative period of ten working days.
Possible outcomes of an alert
| Outcome | Meaning | Note in the record |
|---|---|---|
| Recovered | The work is located | Date of location |
| Returned | It is given back to its owner | Date of return |
| Withdrawn | The evidence no longer justifies the alert | Reason for withdrawal |
| Unresolved | The work remains missing | Alert kept in the archive |
