Didn't Diane Duane eventually do new updated versions of her YA fantasy books? I can't remember the name of the series, but I remember her or someone else talking about how she went back and updated things like the computers and pop culture references.
As David mentioned, she did that for her Young Wizards novels, although not for the parallel Feline Wizards novels in the same continuity (which, despite being about talking cat wizards, are
not YA), so there are some chronological discrepancies between the two now.
Wasn't that done because the last 3 books were solidly placed post-TMP, so it created a more obvious inconsistency when you had all of them together?
Actually, no. When
Swordhunt, the followup to
The Romulan Way, was originally written (and published in two halves as
Swordhunt and
Honor Blade, because
The Empty Chair was delayed but they'd already reserved two slots on the publishing schedule), it was written to take place during the 5-year mission, with an opening editor's note explaining the discrepancy with the previous books. That was under John Ordover's editorship, but by the time Duane was ready to get back to work on TEC, Ordover had left and Marco Palmieri had taken over the project. At that point, they decided to shift the setting to post-TMP for the whole series, so
My Enemy, My Ally, The Romulan Way, and
Swordhunt (reunited as one book) were
all revised to be post-TMP. (Changes in
Swordhunt include changing Uhura's rank from lieutenant to lt. commander and removing a reference to "The Doomsday Machine" being "not so long ago.")
The Empty Chair is the only Rihannsu novel (and the only Duane novel other than
Spock's World) that was unambiguously post-TMP in its original version.
Although, as with Young Wizards, it creates a discrepancy, since
The Wounded Sky and
Spock's World are part of the same continuity but did not have their chronological references, ranks, etc. updated with the rest. Which is why I still prefer the original versions of MEMA and TRW. Which is still reconcilable with the newer books, more or less, since the new ones are set after
Spock's World and thus should be post-TMP anyway.
Another famous example: The original magazine version of "Tarzan of the Apes" by Edgar Rice Burroughs had a scene where Tarzan fights a tiger -- in Africa?
When it was pointed out to ERB that tigers are not native to Africa, he changed it to a lioness in all subsequent editions.
Except that there really aren't any jungles to speak of in Africa either, at least not of the type Burroughs depicts in the novels. So it's incongruous that he changed that one thing but kept the rest.
