The database, a joint project between the U.S.-based Claims Conference and the United States Holocaust Memorial Museum, is based on records the Nazis produced in Paris, and is designed to help families search for art they believe may have been seized.
“This is probably the most famous of the (Nazi) looting, and was done in Paris,” said Wesley Fisher, director of research at the Claims Conference.
“The general assumption is that most of these things have been returned, but it turns out not to be true,” he told Reuters.
The organization, which seeks to return art stolen by the Nazis to its original owners, advised museums, art dealers, auction houses and affected families to consult the listing.
The database includes unrestituted works by artists including Claude Monet and Paul Cezanne, whose paintings can fetch millions of dollars at auction.
