How To Remove A Duplicate Book Title

[Ken]

My book, which was published on August 26 by Balboa Press, was not in your system. So, on the weekend, I added this title Dream Job Discovery – How to Find a Job That Fuels Your Passion and Inspires Your Purpose which is the paperback version of my book.

Then, thinking I was adding the Kindle version (which I had purchased to make sure it worked) to my shelf, I mistakenly added that version as well Dream Job Discovery: How to Find a Job That Fuels Your Passion and Inspires Your Purpose.

Since the Kindle version is from Amazon.ca and not Amazon.com, is it best to delete the Kindle ISBN and leave just the paperback version?

Or is it best to delete both and add the Amazon.com version instead?

Thank you in advance for your help with this. Much appreciated.

Amazon uses the ASIN. Sometimes they differ between countries but I have tested it and the Canada one and the US one both have the same ASIN. So there are no changes that need to be made.
I have combined the two editions under the same umbrella record.

Those are not duplicates, but different editions. The Kindle ASIN is the same on amazon.com. I have added the hardcover.
