Sometimes when you create a Kindle edition, it is posted separately from the print edition so it is appears to be an entirely different book, with two distinct pages. There’s no rhyme or reason why this happens to some books and not others, but it can be a real problem – especially when you’ve cultivated a bunch of reviews for one edition. But even if you haven’t, it’s a good idea to have both editions in one place so buyers don’t have to hunt around for different options.
To link two books together, take these steps:
Email firstname.lastname@example.org and give them the ASIN and ISBN numbers of both editions, and request to have the two books linked together – should take 2-3 days.
