What Ruggeberg edition of IIH should I get?
I am planning to purchase an older copy of the Ruggeberg edition of IIH, in English. A couple different options are available to me: the 2nd edition (1971), the 3rd edition (1976), and the 6th edition (1993). I am inclined to choose the 1993 edition because it is the latest edition, and still the Ruggeberg one. But perhaps one of the earlier ones are actually better translated from the original?
