The "Round Table" of the theatre collections in Berlin is coordinated by the Akademie der Künste and the ITI. It is an internal forum for communication of the theatre-collecting institutions just like for theatres and artists that endeavour the documentation of their work. The portal Berliner Theater Archive provides an overview over and the access to 15 institutions as well as their respective stocks: Akademie der Künste, Berliner Ensemble, Deutsche Oper, Deutsches Theater, ITI/Mimecentrum, Maxim Gorki Theater, Komische Oper, Stadtmuseum Berlin, Freie Universität, Theater des Westens, Theater an der Parkaue, Kinder- und Jugendtheaterzentrum in der Bundesrepublik Deutschland, Universität der Künste, Volksbühne am Rosa-Luxemburg-Platz.
