Do you know the protocol of having duplicate books on your Amazon KDP Select bookshelf? I didn’t before, but I do now. First off, as much as I would like to keep my bookshelf tidy by deleting unwanted things, unfortunately, there is no option to take that action. Maybe there is a way internally through KDP, I’m not sure, but what I am certain of is an author is not able to make it happen.
The alternative solution is to change your active book to an unpublished draft. And, if you want to start off fresh still using the same book title, but not wanting the baggage that goes along with it (e.g. reviews, editorials, etc.) you would then use the option “Add a New Book” to create a new book with the same title but under a different ASIN. To be frank, my thinking was the old, unpublished draft would be closed and obsolete, however, that wasn’t the case.
What I came to learn was if you have the same title book their detail pages automatically link within 48 hours after an additional edition or version is published as long as the content, title, and contributors are exactly the same. The only way to avoid this automatic action in the future is to change a small detail in the title by adding a subtitle or a change to the form in which the author’s name is written as desired. You might perform this with the unpublished draft so the system doesn’t feed and match details for similarities.
Though in my case, since it had already happened, it took a few times going back and forth in correspondence with KDP representatives to get things corrected. Things ended well, but it was a headache getting to that point. Hopefully my experience prevents you from making the same error.
