Relevant databases of stolen cultural property should be consulted commercial and cultural heritage organisations when researching the provenance of objects already in collections or when considering a potential acquisition. The databases listed here are not exclusive to the 1933 – 45 period.
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.
