I tried to think chronologically, but some of the earlier poets ended up later in the list, and after I exhausted the list of things that "HAD" to be there, I went back to other works by the same authors. I could have gotten to 100 easily if I started adding shorter works, like Pushkin's Medny Vsadnik or Tsygane, or Kuprin's Legkoe Dykhanie, or Zolotoy Telenok by Il'f and Petrov.

I should have also mentioned that the names were in Russian whenever the English translation was unknown to me or varied enough.
