With the rise of digitization, broadcasting archives are growing increasingly acces- sible. National projects like LARM, BBC’s World Service Archive Prototype and BBC Genome Project as well as transnational project such as Europeana, EUScreen and Transnational Radio Encounters (TRE) create new possibilities for researchers and enable new histories to emerge. Broadcasting archives are increasingly relevant as collections of cultural heritage and resources for cultural memories, and thus also as objects of ideological mobilisation for national and supranational projects as well as for minorities and communities. At the same time, smaller, private and commercial online archives increasingly challenge large public archives as access points for cultu- ral memory, community and creativity. This workshop welcomes archivists, researchers, broadcasters and radio aficionados alike in a discussion of the practical and methodological implications of such archival transformations. In line with TRE‘s objectives, the workshop focuses on radio archi- ves as repositories of cultural encounters, and asks how collaborations and clashes between cultures have been documented, stored and re-circulated in broadcasting archives, how archival knowledge can be networked to restore the knowledge of such encounters and how the increased availability of archival material may be used to ge- nerate new transnational and transcultural spaces of dialogue. https://transnationalradio.org
