I still remain confused. That is not new in itself, is it? LOL
Does the use of the term a 'new printing' differ in any significant way to a 'revised' edition? Isn't that a distinction with no difference ? [To borrow R Franz's coinage here]
Also - and this seems absurd to the 10th degree - why issue all the changes to made to the old books and then reprint it with the changes?
Any clarification that will help this old fud get that?
