When considering acquisitions of works of art that were made in or before 1945 and whose known provenance suggests that they might have been in areas of Europe occupied by the Nazis between 1933 and 1945, curators research provenance thoroughly prior to acquisition, and once acquired, these objects are listed on this website. The list includes works from European collections with Nazi-era gaps.

Research is ongoing and objects with unconfirmed provenance will be added to this list as they are found.
