The book I read is the first link at the bottom of my message above. In there I randomly picked from the bibliographic references, just to double check: is this so? The second link I've provided above might be the us english language precursor of the book I've read. It has the same primary author and it came up when I googled for the German one. So they seem to be tightly related. I don't know if that has a comparably thorough bibliography, though. And the referenced books from the bibliography were 90% German language papers, agriculture, weaving machines, nutrition, pharmacology, what have you. So: I suggest the above linked books :-)
