"Declassified in Part"? That seems odd, considering that Soviet Celestial-Mechanics Literature shouldn't[1] be under copyright, especially not that published before 1958. Anyone find any interesting "sanitized" parts? I spot checked ~10 pages and didn't find anything beyond an ordinary, if long, review article.

[1] On the other hand, http://diafilmy.su is unexpectedly down. They used to have nice educational filmstrips for orbital mechanics, gratis.
