The Silver Age (Serebrianyi vek) of the Russian literature left priceless hand-written heritage, most part of which has not been studied yet. Writers’ archives include all stages of their literary lives – from drafts and clean copies to marginalia in books, newspaper cuts, copybooks and letters. Archive collections are situated in different cities and not infrequently in different countries. As far as Russia is concerned, the biggest storages of manuscripts, such as archives, scientific institutes and libraries, are located in Moscow and Saint-Petersburg.
