The Norwegian Digital Radio Archive -- The Norwegian Broadcast Corporation (NRK, www.nrk.no) and the National Library of Norway has for six years been working together to digitise the historical radio archive of NRK. The project aims at preservation, professional re-use, and general access. More than 50.000 hrs (170.000 programs) have now been digitised in high quality. The archive is built within the National Library of Norway, but serves as the every-day radio archive for NRK with their headquarters 1000 kms away. The archive is also now the repository where the National Library of Norway stores copies of the daily radio broadcast in Norway, enabling the archive to be updated on a daily basis. The archive is also integrated with FEIDE (www.feide.no), a federated authentication regime for the research and education sector in Norway. Based on the use of FEIDE, the National Library of Norway has established a role-based access control for the archive.
