These are things I currently have in progress
Currently working through Chapters 4-8 of "Gramsci's Laboratory" by Alvaro Bianchi with my 2-person philosopy reading group. In conjunction with this, we'll also be reading or rereading some of the source materials in Gramsci's Prison Notebooks and other writings.
I"m also re-reading at least some of Marx's "Capital" (vol. 1) with another discussion group, along with David Harvey's "A Companion to Marx's Capital".
Then there are these:
"The Darker Nations: A People's History of the Third World" Vijay Prashad
"Freedom is a Constant Struggle" Angela Y. Davis
Nothing specific in mind for the further future. We'll see.
Books I've been reading list -- Not really 50 list -- Home Page.
