Welcome back, Michael,
1. Are the 3 notebooks on the economic crisis of 1857 to
which you refer part of the (I think 23) notebooks on
economics of the 1850's?
2. At the end of your post you mention that you wonder why Marx
begins Vol III with cost price? I have no answer but am curious
if you thought of any altenative concepts that should lead off
the volume. Marx descibes the various parts of Vol III in a
letter to Engels dated 04/30/1868.
