This is a good book. It would be even better if it were typeset in LaTeX.
I wonder if such an effort could be financed from some kind of microgrants. Take old Soviet maths and physics books - they were very good! - translate them into English, possibly with small alterations (e.g. a QR code link to an animation), type them in LaTeX or AMSTeX and release them under a friendly license.
If it was a Western book, definitely, but with books published in the 1980s in the USSR, I am not sure how it works.
The USSR was not a signatory to the Berne convention, so the original rights may be lapsed. Russia joined the Berne convention in the 1990s, but there were some reservations agreed upon that limited the retroactivity.
I think only Russian IP lawyers can answer that question with any precision.
