I agree with you - there are many details that are either missing from the documentation or the books on the topic. Actually reading the code usually provides the necessary _practical_ structures used in the real projects. One of the counter-examples had been the implementation of egalitarian paxos for me: when I had first read the paper I've thought that I didn't understand a lot. By reading throught the code written by the actual author I had realised that the paper by itself described something quite far away from a practically working prototype; So it wasn't my understanding of the paper in the first place that was the problem.
