Change ISBN & ASIN numbers for revised edition

[Chris]

I have a revised edition of THE LOST HEIR by Chris Gourley (new cover, reformatted, corrections and additional material). It now has a new ISBN and ASIN # B09JVRJZWL
ISBN 979-8750170197
395 pages
Could you please correct this for me? Thank you!

I don't think these ASIN and ISBN are new. Both seem to be in the database since 2021.

I understand that you have a new cover for this ASIN and ISBN. We don't remove older covers as readers prefer to see the cover they have. Instead, we create an Alternate Cover Edition (ACE). I created an ACE for the ASIN: The Lost Heir.

For the ISBN the situation is slightly more complicated as it is currently assigned to the Large print edition: The Lost Heir. Was this wrong to begin with, or was the ISBN of the large print edition reassigned to the new edition? Both are valid options, I just need to know which one to do.
