For many years prior to glasnost and before the Ardis editions Chekhov Publisher  of the East European Fund (NYC) published the only Russian-language editions of Nabokov's work. Globus in San Francisco has a few of these rare editions left. Available are: DAR ($25); Vesna v Fialte i drugie rasskazy ($20); Drugie berega ($20).  See http://pweb.jps.net/~globus. Scan down to Chekhov Publishers section.
 
Also listed is a new  bilingual Russian edition of Nabokov's autobiography. This would be very useful for language students and for those wishing to compare the Russian and English versions ($18).
