GoodReads

Naturally, my third book would “not be found” because despite it selling through pre-orders, Kindle paid, and paperbacks, since the sales numbers magically disappear, the book doesn't exist.

I suppose, I will manually enter it using the ISBN, which serves no purpose because it is not like any of my books sales are being tracked accordingly.

GoodReads actually was the site where I started gaining deeper insight or evidence as I like to call it.
