worldcat lists the institutions with this book https://search.worldcat.org/title/1048005393, you’ll probably have to show up in person. You may be able to do an inter-library loan if your local library doesn’t have the book, you could get it from a sister library. However, the only public library that lists having the book is the Austin Public library in Austin, Texas.

If you want the instances to sync, you just need to sync the directory. (I currently use nextcloud sync for this, but in the past I used synching and before that btsync)

If they dont try to modify the files at the same time (with sync delay) there won’t be any issues. If they do grow out of sync, you can fix pretty easily with db repair.

This uses ffmpeg under the hood and muxes the file into a .m4a file without transcoding. Basically keeping whatever compression youtube used for the audio (which is some sort of mpeg4 compatible audio, probably depends a little bit)

This still recompressed, but it’s the best you can do using youtube as the source.

• uploader (almost certainly, but theoretically you could skip this step if you encoded your video well) compresses audio
• uploader uploads to youtube
• youtube re-compresses the audio again (almost certainly transcoding into a different codec)

Churning through senseless trends is a time honoured tradition. Just like beef stroganoff.
