I'm not clear what you mean. I have old editions, each clearly marked in this manner: (not on the glossy cover, but on the appropriate title pages according to Library of Congress protocols) First Edition February, 1993 Second Edition, 1st Printing, February, 1995 Second Editon, 2nd Printing, July, 1995
The February, 1993 edition is obsolete September 1, 1995
Do you not have something similar on your editions?
