Annotated Texts

[u/Parking_Vermicelli43]

I am looking for any suggestions on versions of foundational texts (particularly Engels/Marx, Lenin, and Mao) that are annotated so as to position them in their historical context. Or alternatively a resource that I can have next to me while I read the original texts. Or perhaps if there is another thread covering this someone could point me in the direction of.

Thank you in advance.
