The Central Name Index, with 50 million reference cards on 17.5 million persons, is a globally unique testimony on the crimes of the Nazi Regime and its consequences.
Each of the eleven member states of the International Commission is entitled to request a digital copy of the documents kept in Bad Arolsen and provide this to a national partner institution. This was established in the Berlin Agreements from 9 December 2011. Thus, international access to the documents in the ITS Archive, which is inscribed on the UNESCO „Memory of the World“ register, can be facilitated, not only for scholarly research but also for personal research on family fates.
These Copyholders are partner institutions of the International Tracing Service (ITS). In 2014 a project was implemented for improving user access and achieving a more concerted procedure through regular information exchange among the users. As part of this, the ITS, in a cooperative effort with the Wiener Library and the United States Holocaust Memorial Museum (USHMM), will be organizing a series of workshops through 2018. This project is financially supported by a private British Cultural Foundation.
- Partner institutions holding digital copies are in:
- Belgium: Archives de l'État en Belgique, Brüssel
- France: Archives Nationales, Pierrefitte-sur Seine
- Israel: Yad Vashem, Jerusalem
- Luxemburg: Centre de Documentation et de Recherche sur la Résistance, Luxemburg
- Poland: Instytut Pamięci Narodowej (IPN), Warschau
- United Kingdom: The Wiener Library, London
- USA: US Holocaust Memorial Museum (USHMM), Washington
Every year the ITS transfers to all the partner institutions an updated version of its digital holdings which includes all newly scanned documents.
