Jeff Tucker at Mises.org has just announced the full release of the online version of Uncle Murray's astounding two-volume set on the history of economic thought. Read them and weep:
=> Economic Thought: Before Adam Smith - An Austrian Perspective on the History of Economic Thought, Volume I
=> Classical Economics: An Austrian Perspective on the History of Economic Thought, Volume II
All Jeff has to do now, is to get Tom Woods to volunteer to write the unstarted third volume; 'The Twentieth Century and the Madness of the Keynesians'.
In the meantime, you can get the beautifully produced hard-copy versions, here.
