Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
Amazing book. I have purchased Logolepsy books offline. I am happy to see there books online. Thank you Amazon for such quick delivery.
* Shrink Packaging of books to avoid soiling. Excellent packaging I must say! * FSC Grade Natural shade text paper which makes the book very light-weighted and portable * The cover has a beautiful design with an amazing matte lamination! * Cost is pretty much justified for a book finishing of this quality.
