The Barabtarlo Collection consists of letters, postcards, emails, manuscripts, photographs, audiocassettes, and videocassettes. These items were collected by Gennady Barabtarlo over the course of his association with the Nabokov Family and with Alexander Asarkan.

This series primarily consists of letters from three members of the Nabokov Family. It also includes miscellaneous documents, photographs, and audiovisual materials collected by Professor Barabtarlo. Professor Barabtarlo corresponded with Nabokov's widow, Véra Evseevna Nabokov, from 1979-1990. Much of their correspondence relates to Professor Barabtarlo's translation of Nabokov's English language works into Russian, including his novel "Pnin", short stories, and biographical essays. Most letters are in English and typed by Mrs. Nabokov's secretary. Some are in Russian and handwritten by Véra Nabokov. During 1979-1988, Professor Barabtarlo also corresponded with Nabokov's sister, Elena Vladimirovna Sikorski. Their correspondence centered on her family's life in Russia and subsequent emigration, as well as on aspects of Nabokov's fiction writing. Elena Sikorski's letters are in Russian and handwritten. The final group of correspondence, in English, is between Professor Barabtarlo and Nabokov's son, Dmitri, from 1987-2007. The correspondence largely concerns questions pertaining to Barabtarlo's translations of various editions of Vladimir Nabokov's works into Russian. Other topics mentioned within the correspondence are related to the controversy surrounding the publication of Nabokov's unfinished novel, "The Original of Laura" (See collection folder for Barabtarlo's remarks (1 leaf) on this.)

This subseries consists of correspondence from Véra Evseevna Nabokov, Elena Vladimirovna Sikorski, and Dmitri Nabokov.
