I was noticing when I looked at some kindle books on Amazon's site that some will have a section next to customer reviews at top (near the graph of stars) where there are quotes such as "This book is easy to understand..." and it will say 7 reviewers made a similar statement.. Is this something that is inserted by the author or is it done by Amazon?
Some books also have editorial reviews at the top, before the customer reviews. Is that something inserted by the author? It is above the product details and are quotes with a name after them.
Many books don't have either of these areas so I was curious about this.
