I have a reference question. I wonder there're any good English-language collections of major CR documents or official talks. For example, like 5-16 notice, 16 articles, Lin Biao's 5-18 talk, etc. Several might be available on the internet but I still prefer the printed source. I know about Michael Schoenhals' book but it seems to be more a documentary history for teaching purpose, rather than a serious reference collection.
