This summer I have a book coming out from the Historical Materialism Book series. You can read more about it here (as well as freak out at its price, but it will be out in paperback from Haymarket in a year). The book is mostly made up of pieces that have appeared before in various journals, some now defunct, although there are a few new pieces, an essay on Sohn-Rethel that I never found a home for, as well as a piece on "Spontaneous ideology" and Deleuze and Guattari's idea of social subjection/machinic enslavement.
