NOTE

The note concerns the systematization of Stalin's personal library. "It all began with the library in the first apartment," writes E.S. Gromov, "around 1920. Its owner was evidently completely indifferent to rarities, to bibliophilic treasures. The General Secretary simply had no time for them. He needed the library strictly for work, for current tasks, references, information, as well as for relaxation. Social-political and historical books and journals predominated. Stalin had felt a strong pull toward history, including military history, since his youth. He also kept the works of political opponents, above all Trotsky. Naturally, he had all of Lenin, read and reread. Nor was literary classics forgotten, although initially there were few of them: Lev Tolstoy, Garshin, Gorky, Chekhov, Uspensky..." The wife of S.M. Kirov, who also had a large library, once suggested inviting a librarian to systematize the books. "Kirov objected: 'Comrade Stalin's wife invited a librarian, who arranged the books according to all the rules of library science. And then Comrade Stalin could not find a single book without the catalogue and rearranged everything his own way'" (See Gromov E.S. Stalin: Art and Power. Pp. 58-59). By the end of his life, Stalin's library comprised no fewer than 20,000 volumes.
