I've added a new edition to my book with a new cover. I've succeeded in making it the default or primary cover. However, since the ISBN is attached to the first edition, there is a problem with the link to buy on the new edition. It searches using only the title, and leads to a different book from my own. Is there a way to attach the ISBN to the new edition? The old edition directs correctly - I assume because of the ISBN. Thanks to anyone who can help.
At this time, there is no workaround for this problem. The 'get a copy' links search first by ISBN, and if that is absent, they search by title instead. From personal experience, if I can't get the book I want directly through the 'get a copy' link, I check to see if there is a url on the Goodreads page, which often will redirect me towards the correct sale page. I have added your website as the url for that edition. Hopefully that will help.
Thanks to anyone who can help.
