"BookAuthority uses a proprietary technology to identify and rate the best books, using dozens of different signals, including public mentions, recommendations, ratings, sentiment, popularity and sales history. This includes maintaining the most comprehensive collection of book recommendations from domain experts such as Elon Musk, Warren Buffett, Prof. Daniel Kahneman, Sheryl Sandberg, and David Allen. Only the very best books are featured on BookAuthority. To keep our site objective and unbiased, ratings are calculated purely based on data. We do not accept requests to feature a book, nor are we doing business with publishers or authors."
