Work on the Historisch Kritische Wörterbuch des Marxismus (HKWM) project began in 1983, the year of the 100th anniversary of the death of Karl Marx. In over 15 volumes including 1,500 entries, numerous authors define and explain Marxist terminology. So far, volumes 1 to 8/II have been published; some of the most important terms stem from these volumes.
The journal Historical Materialism has published some further terms in English.
