The debate focused on the published book, because Sholokhov's archive was destroyed in a bomb raid during the Second World War and no manuscript material or drafts were known. 143 pages of the manuscript of the 3rd & 4th books were later found and returned to Sholokhov; since 1975, they have been held by the Pushkin House in St Petersburg. Then, in 1987, several hundred pages of notes and drafts of the work were discovered, including chapters excluded from the final draft. The writing paper dates back to the 1920s: 605 pages are in Sholokhov's own hand, and 285 are transcribed by his wife, Maria, and sisters. Sholokhov had had his friend Vassily Kudashov look after it, and after he was killed at war his widow took possession of the manuscript, but she never disclosed it. The manuscript was finally obtained by the Institute of World Literature of the Russian Academy of Sciences in 1999 with assistance from the Russian government.
