Book recommendation on Bolshevik organising during the Stolypin reaction.

Hello.I'm currently reading "History of the CPUSA (Bolsheviks) Short Course", and I've just finished the chapter on the period of the Stolypin reaction.In it, they mention the importance of a synthesis of illegal and legal work, using any legal channels possible to stay in touch with the masses.This is interesting to me, but I'd like to read some actual, more thorough, descriptions of what exactly this organising looked like, in detail.Do you know of any book/articles that go into specific details on this matter? Surely even during these heightened times they still kept minutes of their meetings! :)Preferably in English, my Russian is still sub-infant level. via /r/communism https://ift.tt/3glL628
