What's the legal position on sharing broadcast transcripts? I've recorded a couple of recent Wikimedia-related radio interviews and transcribed them to avoid sharing the audio. I was thinking of sharing transcripts through this list and perhaps a press archive on the Wikimedia UK site. My instinct is that the content of the conversation, unlike the audio itself, is non-copyrightable, but online I've seen some descriptions of transcripts as derivative works. I'm rather keen not to get the chapter in trouble!
