The Central Registry of Information on Looted Cultural Property 1933-1945 provides a database of over 25,000 missing and looted objects from over 15 countries.
The Lost Art Internet Database contains data on cultural objects which as a result of Nazi persecution or direct consequences of the Second World War were removed and relocated, stored or seized from their owners, or are cultural objects where, because of gaps in their provenance, loss cannot be ruled out as a possibility.
INTERPOL publishes stolen cultural property in the Stolen Art Database. The database contains only those objects that have been officially reported as stolen by member countries.
London Stolen Arts Database stores details and images of 54,000 items of stolen property. Items are included in the database if they have good descriptions and qualify as pieces of art, antiques or as cultural property.
