A new book by Richard C. Borden points out some interesting connections between Nabokov's SPEAK MEMORY and Valentin Kataev's memoir MY DIAMOND CROWN (1977, which mentions VN several times), pp. 114-116.
 
Those interested in the post-Stalin rebirth of Russian modernism will find much of interest in:
"THE ART OF WRITING BADLY: Valentin Kataev's Mauvism & the Rebirth of Russian Modernism" (Northwestern UP: Evanston, 1999). In addition to Kataev Borden examines Aksyonov, Limonov, Erofeev, Bitov, and Sasha Sokolov.
