You said Lolita, right?
Of course. Vladimir Nabokovs Lolita, published in 1955 and made into a film directed by Stanley Kubrick in 1962, is the work most identified with the Russian-American author. Its entered into the parlance, seeped far into the public consciousness: even popular music in the 80s featured Sting referring to the novel and its author in the Police song, Dont Stand So Close to Me.
But theres a lot more to Nabokov than the yearnings of Humbert Humbert. And this week for the first time in 50 years without special permission researchers can visit the Manuscript Division of the Library of Congress for access to a vast array of papers donated to the Library by Vladimir Nabokov (1899-1977) and members of his family, from materials related to Lolita to background on his numerous novels, short stories, poems, literary criticism and film treatments. Most of it is in English or Russian, although some is in German; some of Nabokovs materials are written under the pen name V. Sirin.
One other note Vladimir Nabokovs character may have gotten butterflies pursuing a nymphet, but Nabokov got butterflies pursuing butterflies: he was an accomplished lepidopterist.
