The International Tracing Service (ITS) is a center for the documentation of National Socialist persecution and the liberated survivors. It was founded as a tracing service immediately after World War II to help reunite survivors with their families and clarify the fates of those murdered and those missing. Today, the ITS is also an archive and open for research. In the future, parts of its archived collections will be made accessible to the interested public on this portal, thereby broadening the knowledge of these unique documents and the research potential associated with them. At the same time, by way of the comment function, we would like to encourage exchange about the collections – not only among users, but also between users and the ITS archive.

Thanks to the valuable help of our users, we have succeeded in returning a number of effects to their owners, or the owners’ families, since this portal went online in 2015. We’d therefore like to call attention to the effects of unknown origins still in our holdings.

The ITS is working on making even more collections available on the portal in the future, along with the most comprehensive possible research functions. The portal, it should be added, is no substitute for a direct visit to the ITS archives in Bad Arolsen. We welcome your comments about this portal so that we can continue to improve our service.

The use of the portal is free of charge; donations are always welcome!

About the ITS Holdings

The ITS Archive preserves one of the largest collections worldwide on the history of the Holocaust and the National Socialist concentration camps, on Nazi forced labor and on so-called displaced persons. The holdings contain original documents on the registration and care of the survivors after 1945, as well as documents the Allied forces were able to secure when they liberated the concentration camps, for example prisoner identity cards from the Buchenwald and Dachau camps. Correspondence with survivors of Nazi persecution and their families, conducted as part of the process of clarifying their fates, constitutes another part of the holdings. Finally, the ITS stores numerous copies or microfilms of documents from other archives or public institutions, which it collected in order to meet its own tracing responsibilities. In June 2013, the ITS’s original collections were added to the UNESCO “Memory of the World” registry.

A complete inventory of the ITS’s archival collections and other indexing information (the digital copies themselves are not available) can be found here as well as on the portal of the „European Holocaust Research Infrastructure“ (EHRI). The finding aids published on the two websites, however, adhere to a structure different from the one chosen for the publication on this portal. That is because archival indexing geared towards the interests of historical research has only recently become one of the ITS’s priorities.

Moreover, provenances customary in archives have been re-organized, and documents grouped according to pertinence. Whereas the finding aids reflect the original provenances, in this portal, for technical reasons, the system by which the documents are actually organized in the ITS archive has been retained.

Here, too, the reconfigured collections are not indexed according to uniform criteria and are thus displayed in different ways. This explains the differing research criteria: the personal effects sorted alphabetically according to owner's name, as well as the card index of the Reich Association of Jews in Germany (Reichsvereinigung der Juden in Deutschland), can be searched not only via personal name but also via date of birth; the death march collections on the other hand, can be researched according to place names and by way of a geographical map. Research in the children’s tracing service is carried out in keeping with the file structure. Each collection is accompanied by an introductory text explaining the origins of the respective documents.
