Adding Soviet Books

[Shriya]

I have recently developed an interest for books published in the USSR from 1917 to 1991. I also posses some rare ones like Kostya Ryabtsev's Diary: Scenes of School Life, September 1923-June 1924. However, most of these books and a page for their authors are not listed on Goodreads. The list included Anton Chekhov, Vsevolod Ivanov and a few others, who definitely deserve a mention. I have added information about all the authors and the books that I could find. However some additional information is needed about a lot of others likeN. Ognev and L. Kassil etc. Could someone help me, please?
