The portal Jewish History Online is a meta-platform for simultaneous searches in the content of various digital projects. The service is hosted at the Moses Mendelssohn Center for European-Jewish Studies in Potsdam and is being developed jointly with the Institute for the History of German Jews in Hamburg. The aim is to make thematically relevant content from different projects accessible via a common interface for the first time, thus enabling easier access to small databases or editions and opening up new perspectives on one's own research questions. The portal character also contributes to a greater visibility of the participating projects. The Key Documents Edition published by the IGdJ is one of the four projects that have been involved right from the start. Have a look:
