Das Kapital in German is at Michio Akama's web site
http://www630.cpm.ehime-u.ac.jp/AkamacHomePage/Akamac_E-text/Kapital/Kapital.html
It is from the MEW, i.e., the 4th edition.
There are still a few chapters missing.
Michio also started the Theories of Surplus value.
Part of the work was done by me, I have sent her those things which I
scanned in for my own work, but the overwhelming majority of the work
was done by Michio. I also have scanned in the first chapter of
Capital II, the chapters on credit of Capital III, the whole
Contribution to the Critique of Political Economy, and Marginal Notes
about Wagner, all in German, and will send it to her after I have
proofread it etc., it may be a few months until I get to it.
