The National Archives is the international epicenter of Holocaust-related research. NARA holds millions of records created or received by the U.S. Government during and after World War II that document Nazi war crimes, wartime refugee issues, and activities and investigations of U.S. Government agencies involved in the identification and recovery of looted assets (including gold, art, and cultural property)—as well as captured German records used as evidence at the Nuremberg International Military Tribunals. We not only hold these records, we provide access to them.

Citizen Archivist Transcription Mission:
World War II Looted Art

The Third Reich’s Einsatzstab Reichsleiter Rosenberg, or ERR, was the main agency involved in the systematic looting of cultural treasures in Nazi-occupied countries. Hitler ordered that all looted art be placed at his personal disposal. These plundered treasures and gold were hidden in castles such as Neuschwanstein Castle in Hohenschwangau, Germany, and in salt mines such as those found in Altaussee, Austria and Merkers, Germany.

For this World War II Looted Art transcription mission, help us transcribe property control cards which include information indicating to which country Nazi-looted cultural objects were restituted. In addition, the cards may include information such as artwork classification, measurements, identifying marks, history and ownership, condition and repair, arrival, destination and exit information, and the disposition of each item. In some cases, a photograph of the artwork is attached to the corresponding card.  These cards are digitized microfilm, so many are dark and low contrast. There is no need to mimic the layout of each card, just capture the data found within each field.

As digitization standards have evolved throughout the years, NARA has worked to keep up with best practices. However, despite our efforts to stay ahead of the curve, there are still photographs in our Catalog that were digitized many years ago and don’t necessarily meet the requirements to be considered “high resolution.” Specifically, researchers are likely to come across GIF (Graphics Interchange Format) files, which is more or less an outdated format in terms of digitization. While we are currently working to replace GIF files in our Catalog, in the meantime, researchers may be able to obtain higher resolution JPG/JPEG (Joint Photographic Experts Group) and TIF/TIFF (Tag Image File Format) versions by searching Wikimedia Commons. The following is a step-by-step guide on how to find JPG and TIF files when the only version available in our Catalog is a GIF.*



You find a GIF file in the National Archives Catalog. Highlight and copy the National Archives Identifier number.



Go to Wikimedia Commons and paste the National Archives Identifier into the search bar (located in the top right-hand corner).



If there are any higher resolution copies of the photo available on Wikimedia Commons, the files usually appear within the top 5 search results.



After choosing the file format you want to use (JPG, TIF), click “download.”



Choose file resolution.

NARA staff have been working to add higher resolution versions to series that were originally uploaded as GIFs, so there are some instances where there are multiple file types available to download from our Catalog. In instances where a GIF and a JPG exist, but there is no TIF version, it is worth searching Wikimedia Commons to see if a TIF is available. The following is an example of that scenario.



*Please be aware that these instructions only apply to older digitization project in which GIFs were the original files uploaded to the Catalog.
