First is the description of the book, not a summary. Sufficient description should be given so that the reader, as he reads the review, will have some understanding of the author's thoughts. This account of the contents of a book can often be woven into the critical remarks. Second, something about the author. Biographical information should be relevant to the subject of the review and enhance the reader's understanding of the work under discussion. Third, an appraisal, preferably indirect, through description and exposition and based on the aims and purposes of the author. While a critical review is a statement of opinion, it must be a considered judgment including, a statement of the reviewer's understanding of the author's purpose; how well the reviewer feels the author's purpose has been achieved; and evidence to support the reviewer's judgment of the author' achievement. When finishing the minimum essential of a book review, we now come to another point: preliminary mechanical steps.
