Change Book Cover > Likes and Comments

I have librarian status but would still like to check in about correcting a book cover to one of my books. I read in the librarian manual this was possibly against the rules, even if it is my own book. I have changed the cover many years ago once I started my own publishing company, however the ISBN and ASIN used did not change, as the book was set up 10+ years ago with the proper ISBN under my company, but the improper cover, because that's what Amazon was using at the time. It has since been fixed. How do I update to the proper cover. If needed, we can change the book with the old cover to the old ISBN if needed. FYI - the old publisher no longer has rights to sell the book, so that cover is out of print/no longer sold.

CORRECT:
Book Title: The Invisible Enemy II: Vendetta
ISBN: 978-0996639712
ASIN: B006VOLIHI [kindle]
Publisher: Black Fox Imprint


OLD
Book Title: The Invisible Enemy II: Vendetta
ISBN: 978-1608444328
ASIN: none
Publisher: Dog Ear Publishing

If the ISBN remains the same (or ASIN for Kindle and Audible editions) you can add an alternate cover edition.
If the ISBN has changed add a new edition.
