ISBN - 1 unfound, another misplaced?

[Blue]

I listened to Hard Eight on Overdrive (and I swear the ISBN was not on Goodreads a week ago).

Info from Overdrive:
Publisher: Macmillan Audio
Edition: Unabridged
MP3 audiobook
ISBN: 9781427217066
File size: 245980 KB
Release date: October 25, 2007
Duration: 08:37:24
Number of parts: 7

1) I found an edition that matches that information, even with 'Overdrive' in the edition (which I have not seen before) BUT the ISBN is different.
https://www.goodreads.com/book/show/3...

2) I did an ISBN search and found this: https://www.goodreads.com/book/show/2...
However that date does not match up.

I did an ISBN search on the Overdrive ISBN (the second linked edition) and found WorldCat, but no entry for the ISBN in the edition I linked first.

What ought to be done in such a case?

Do you mean that all ISBNs ought to be added if nothing is found in the search, or that if the ISBN is valid some program/spider will have already grabbed it and put it on Goodreads? I have been having the issue of listening to something on Overdrive and nothing coming up for the ISBN on Goodreads quite a bit, including for book nine of this series.

In this case, it appears the ISBN was added, but somehow the information that bast matched what I listened to had a different ISBN and that ISBN is not listed in WorldCat. What course of action would you recommend?

Worldcat lists the edition with your ISBN: https://www.goodreads.com/book/show/2... as published 2007 and as there aren't other details that differ I think you can change the date on it (wait for other opinions, though).

Goodreads has automated imports - bots, but I don't think they can import everything ever published (at least, not yet). On the edit page if you click on "Librarian Changelog" and then filter to "this edition" and the changes were made by something like "amazon_kcw", "barnes noble", "onix ingram" - non-user profile, then that would be them.

And worlcat (great though it is) doesn't have listing for everything ever published, either.
