Archival Databases

Jewish Digital Cutural Recovery Project (JDCRP)

Jewish Digital Cutural Recovery Project (JDCRP): In July 2021, the JDCRP completed its pilot project co-funded by the European Union (EU): The Fate of the Adolphe Schloss Collection. The goal of the JDCRP pilot project was to test the feasibility of building a comprehensive database containing historical-archival information about Jewish-owned cultural and artistic objects that were forcibly displaced between 1933 and 1945. The database provides information on artworks looted, the people and organizations involved as well as a historical timeline.

The second part of the JDCRP’s pilot project is to link archival repositories on Nazi-looted cultural property focusing on populating its emerging cross-searchable digital data platform. The project will consolidate a selected group of digitized archival data on plundered cultural property to enable keyword searches at the document level. Archival material from the Wiesbaden Central Collecting Point of the American Allied Forces, as well as from the records of the Einsatzstab Reichsleiter Rosenberg (ERR) Nazi looting agency will be included. The Claims Conference is among the sponsors of this project.

International Research Portal for Records Related to Nazi-Era Cultural Property

The International Research Portal for Records Related to Nazi-Era Cultural Property  is the result of collaboration among archives and research institutions from a variety of countries to provide online access to widely-dispersed records of the Nazi Era. The online research tool is dedicated to extending public access to the widely-dispersed records of the Nazi era. The Claims Conference is a participant in its own right but also has enabled through its various projects the involvement of many of the other governmental and non-governmental participant organizations.

The Ministry of Culture of the Russian Federation on its website entitled “Cultural Values-Victims of War” in a section on “Moved Cultural Values” has published a partial list of paintings, drawings, graphics, archaeological objects, musical instruments and other categories of objects that were brought into Russia by the Soviet Trophy Brigades at the end of World War II.

So far, objects listed have overwhelmingly been objects taken from museums and repositories in Germany and other states that were enemies of the Soviet Union during the war, which under Russian legislation are not subject to restitution. So far as is known, specialists in Germany trying to track what was taken from the various German museums after the war that still is in Moscow and elsewhere in the former Soviet Union are almost the only ones outside of Russia following the listings. Since much of what the Soviet Trophy Brigades took included many objects looted by the Nazis and their allies from Jews and others of their victims, it is not impossible, however, that some such objects may be in the listings, although in all likelihood only by accident. Although parts of the website are in German, English, and French, the catalog of the objects is exclusively in Russian. To make the listing better known to non-Russian speakers, the Claims Conference/WJRO presents on its website a translation into English by Yagna Yass-Alston of all the listings of painting as well as those graphics that are by known artists:

  1. – paintings 2016
  2. – paintings 2018
  3. – works on paper 2016
