On International Holocaust Remembrance Day, the European Commission encourages staff to take part in the crowdsourcing project #everynamecounts by the Arolsen Archive, by transcribing the information from the registration files of prisoners into a digital archive whilst remembering their names and stories. The archive contains around 30 million documents with references to the fates of 17.5 million people. In order to allow researchers and decedents to access the data, Arolsen are building the world’s largest online archive on people persecuted and murdered by the Nazis and their collaborators.
