Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.
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.
What really irritates me,as a C.A. Smith fan is that Out of Space and Time and Lost Worlds both were issued in two volumes,with different stories in each volume.I have Out of Space and Time vol.2 and Lost worlds vol.1.However none of these listing note which volumes these books are.Furthermore there is no way of contacting the sellers to rectify this situation.Lets hope someone from Amazon reads this and gets the information from the booksellars,so I don't have to purchase 3 or 4 Lost Worlds vol.1s before I finally get volume2!
