WARNING: Art historians who cite these sources should know that they contain omissions and outright lies concerning Nazi looted art.

Provenance online resources: Lost Art Internet Database Of Deutsches Zentrum Kulturgutverluste

The Deutsches Zentrum Kulturgutverluste has a large data base with a powerful search engine for cultural objects that were seized or stolen under the Nazis, most often from Jews.

Provenance research: excellent data base at the Getty

To search Knoedler dealer records, the Getty provides a powerful tool.

Its online provenance research database contains more than 43,700 records transcribed from the 15 stock books of Goupil & Cie/Boussod, Valadon & Cie in Paris (1846–1919) as well as nearly 40,300 records transcribed from the 11 painting stock books of M. Knoedler & Co. in New York (1872–1970).

Hello world: New site for gathering useful links for provenance research

Links to searchable data bases will be added gradually. The aim is to make it easier for anyone who wants to research provenance to do so.
This is an open project. If you would like to contribute, please leave a message or contact through the site.
Thank you.
