I've decided to start referring to the '97 Special Edition as the "Second Edition" of the SWT, being that it has attempted to replace the original "First Edition". Then comes the "Third Edition" in 2004, and then the "Fourth Edition" in 2011. (Fourth time, Force time unlucky!?)
While I think of it, I'll throw in "Edition 1.5" if you want to count the addition of the "A New Hope" subtitle.
