"When Nabokov started translating [his memoir] into Russian, he recalled a lot of things that he did not remember when he was writing it in English..."

"It came out in Russian and he felt that in order to represent his childhood properly to his American readership, he had to produce a new version. So the version of Nabokov's autobiography we know now is actually a third attempt, where he had to recall more things in Russian and then re-translate them from Russian back into English."
