Character entropy of Voynichese

As a sidenote, all problems with the modern copyright model are because it is not in concordance with the modern technological foundations of our society. To try to enforce copyright in our days is much like trying to force folks to ride horses when there are autos for more than a century there. New society needs new models.

But copyright issues are of course off-topic in this thread, so anyone interested in this discussion please open a separate thread.

Returning to the book, I checked the concept of "fair use" in the US law (which is the place of copyright of this book) and there is the concept of the "research" purposes, and also it matters whether the reproduction of the copyrighted material does influence the market value or does not. In this case the book is long out of print, and the content (teaching people to use BASIC) is obsolete, and the prices at Amazon speak for themselves. So in my understanding taking photos of three pages and sending them in private for research purposes does fall unto the "fair use". But to avoid any mischief, it is common in science and engineering to just procure permissions for reproduction from the copyright holders.
