To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
A wonderful book on so many levels, truly a classic. Our daughter received a copy 45 years ago when she was 2 years old, kept asking us to read it to her. We have given copies to many new babies, something they normally wouldn't likely see other wise. Normally, we have to special order which is a nuisance.
