Essential (translated) russian chess books?

Yeah, I think you are right.  There is only 75 games and 284 pages in the Spanish translation, and I think the English is probably the same.  The adapter made a selection from the games.

Viswanathan Anand writes in the introduction to Artur Yusupov's Build up Your Chess 1 The Fundamentals that Yusupov has "mastery of the methods of the Russian chess school," so Yusupov's 9 book series might be worth a look.  Yusupov himself says his inspiration for grading the material by difficulty came from the Russian books of Victor Golenishchev.

ChessOK has released software versions of some of Golenishchev's books in English: Chess Guide for Club Players, Chess Guide for Intermediate Players and Chess Tactics in Open Games all of which run on Peshka.

Chess King produces apps for Android phones or tablets featuring material from books by Victor Golenishchev, Sergei Ivashchenko, Alexander Kalinin and Victor Khenkin translated from Russian.

The apps give you a couple of sample lessons for free, but you have to make an in-app purchase to get them all.

On the FIDE website, there is a list of recommended Russian books by IM and FIDE Senior Trainer Anatoly Bykhovsky:

http://trainers.fide.com/recommended-books.html

He recommends Kasparov, Victor Khenkin, Kotov, Yakov Neishtadt and Alexei Suetin, but for trainers, he gives Golenishchev and Ivashchenko.  He also cites other books specifically designed for 1st through 4th category players by GM Valery Chekhov, Vladimir Barsky and Gregory Bogdanovich.  I don't think these books have been translated into English.

Konstantin Sakaev and Konstantin Landa provide a reading list in The Complete Manual of Positional Chess: The Russian Chess School 2.0 -Opening and Middlegame: Rubinstein, Alekhine, Capablanca, Alexander Panchenko's Mastering Chess Middlegames and Theory and Practice of Chess Endings, Shereshevsky's Endgame Strategy and Contours of the Endgame, Portisch and Sarkosy's 600 Endgames, Israel Gelfer's Positional Chess Handbook 1-2, Alexander Kotov's Think like a Grandmaster, Max Euwe's Strategy and Tactics a course of chess lectures, Nunn, Dorfman, Tukmakov, Dvoretsky, Beliavsky and Mikhalchishin's Intuition, tactical puzzles by I.L. Slavin, Sergey Ivashchenko, V.A. Konotop and S.V. Konotop, Vlastimil Hort and Vlastimil Jansa's The Bext Move, and Volokitin's Perfect Your Chess.

Sergey Ivashchenko's Chess School Manual of Chess Combinations series is available in a multilingual edition including English from the publisher, Russian Chess House.

I.L. Slavin has a 15 book series starting with mate in 1 problems, and building all the way to 1st category level.  I don't think it has been translated.

I've posted here almost 12 (TWELVE ) years ago about a translation from a Russian booklet and then, completely forgotten about it...

That link to the FIDE Trainers website no longer works and the list is no longer on the FIDE website (or not in a public part of the website), but somebody posted the list on Reddit. See FIDE Trainer's Commission (TRG) list of recommended books (July 2020, but the list was from 2018, apparently).

That a long list
