Since I wrote the above, I found where this had been discussed before. I guess if we want it, we would just have to copy from the internet places for our own personal use and not share it. Is that the way you see it?
Yes, the last I looked, this work had its copyright restored. It will eventually fall back into the public domain, but I don't know when, and, I recall seeing legal warnings sent to people who were still distributing it.
