I've mentioned before Sir Winston Churchill's multi-volume, heavy, out of print, hard-to-find in public libraries, history of World War I, the
World Crisis -- which I've read is better than his outstanding World War II history.
Justificaton for this post : A fresh search shows World Crisis volume 1 became available, this year, as an uncorrected Canadian optical character recognition scan, at archive.org:

I think it's still under copyright in the US, and thus should only be downloaded by Americans (and Europeans?) when visiting Canada. But -- let's call it fair use -- I just peaked in a few spots, and find the volume of OCR errors is fewer than the norm. To me, it's readable.
However, if I understand Canadian copyright law correctly (highly questionable), they cannot upload any subsequent volumes, as they were published after 1923, and the Copyright Act of Canada came into effect in 1924.
In just over three years, all Churchill's works go into public domain in Canada, but I expect it will take years after that for volunteer proofreaders to fix the scan errors.
Yes, I am aware this post makes current copyright law look absurd
