What to read after The German Ideology?

"This new edition makes easily available the really living parts of the authors' first exposition of the new revolutionary philosophy, written with all the freshness of a new discovery. It includes the vital first part of the book, which remains a basic text for every student of Marxism, and the most telling points, fully relevant today, out of the polemics which occupy the rest of the work. Added as appendices are Marx's famous theses on Feuerbach and his unfinished "Introduction to a critique of political economy," not previously published in English. The present edition has been edited by C.J Arthur, of the School of Social Studies at Sussex University, England, who supplies a lucid introduction on the place of the work in the evolution of Marxism"--Page 4 of cover.
