The full audio of the cassettes are available at on YouTube and FaithMAndP.com.
It would be good if someone could 1) do some đŸ“–digital preservation of these, 2) create text transcripts of each, using AI, and 3) make the complete text of all cassettes available in some easily-searchable form.
The goal would be to make the information more accessible in terms of "crime scene analysis", by critical researchers. But I suppose some pro-Freeman folks might use it for their own purposes too.
The first step would just be to download all the audio from YouTube. After that, I don't know if it would be possible to get any established digital preservation organizations to take them? Such as archive.org?
To a large extent, YouTube may have already created transcripts for these videos. TODO: Look further, it may be possible to mass-download these transcripts.
