There aren't many societies to write about. The Paris Commune lasted too little and Marx himself covered it in "The Civil War in France". On history of the Soviet Union prior to like 1940s "The History of the All-Union Communist Party (Bolsheviks): Short Course" is a good read – bolsheviks had to analyze their history to keep on rolling. I have to mention that even in the USSR, if we take the criteria for Socialism from "The Critique of the Gotha Programme" – "single-mode" economy with no kolkhozes or other kinds of even collective private property and moneyless product exchange inside the country with the dictatorship of the proletariat –, Socialism was not achieved. After 1953 things go bullshit.
I can send links to some materials my buddies have made on the class struggle, economy and politics in the USSR, but they are in Russian yet.
In general, go read Marx and Engels first, then go for Lenin's and Stalin's works, they're good, just don't buy the Plekhanov's bullshit about "Marxist philosophy" – Marxism is a science.
