I was a little tough on the Okudas earlier in the thread, but all the same I would seriously
still buy an updated copy of this. There's so much more new material that could be added since the last edition (1996?), including of course that Paramount has now pronounced the TAS as canon, or near enough to it.
I do still take whatever the Chronology actually says with a grain of salt, however. It's a great book, but not a definitive text IMO.
