Broadcast documentary makers – what do you do with your historic interviews tapes?

I wrote an article for Britain Journalism Review (BJR) last year on what journalists do with their paper and digital archives and what are the problems of preserving ‘the first draft of history’.

I’m  following up with a natural second part to this which is: what to do about all those significant interview videos and audio tapes that are in warehouses and are historic in value. I made three Timewatchs in the 1990s with people who have never otherwise been interviewed. I interviewed at length a range of USAF (SAC), RAF and Red Air Force officers, from generals right down to crew, and then a long list of Cold War players including J K Galbraith. I would say many are of historic value and only a few minutes were actually broadcast.

There were lots of other significant interviews in other projects I worked on. Mostly we edited in 30 – 60 seconds but there were dozens of hours of tapes. While I have transcripts in my paper archives the beta tapes are stored somewhere by the independent TV company I was working with and I suspect other journalists and film-makers have this problem. Please tell me your story:
