A Book Review is moreso an individual reader’s personal taste in the book whether it be the writing style, novel’s topic or even the genre. A reader’s mood swing at the moment can affect their review.
While an Editorial Review is less personal and more professional. It can be a great tool in increasing book sales. It’s where the reader points out the pros and cons that makes a book great or not so great. It’s more of an evaluation.
Although, both works to the advantage of the book getting into the hands of other readers. Book reviews have the greatest allure to the general public because they are written by everyday readers not professional analyzing the book. But when professional marketing it’s the Editorial Reviews that pulsl the punch.
