The Landesarchiv Berlin has expanded its cooperation with the Projekt European Holocaust Research Infrastructure (EHRI) project as of the beginning of 2023. EHRI forms an EU-funded, transnational association of research and educational institutions whose target is to further internationalise and network research on the history of the Holocaust. In this context, the EHRI portal is used to compile information on the respective archives that hold material on the persecution and murder of European Jews.
