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.
These Seymour Simon (Smithsonian) books are a joke. $7 dollars for a book that is thinner than most magazines. Ridiculous, your paying for the Smithsonian name only. I bought a few of these books at the same time and I have regretted wasting my money since they have come in. The people who give good reviews are either too easily impressed or just don't know what a good book is. Buyer Beware!
