Any other information: There is no formal catalogue for the material, beyond terse file names indicating the topic and/or participants. However we do have printed listings for around 80% of them. The listings are limited - they consist of the opening script of the programme, which gives a one-sentence description of the speakers and topic, plus a music listing. They are printed only, not digital.
We would welcome the provision of resources to fully catalogue the programmes and transcribe the written descriptions to digital form.
