An editor of a journal wants to publish a book review of a recently published book and makes a relevant professor, who has read and used the book, to do it. The problem is the editor is not an expert in the specific subject matter of the book, therefore, can not make any judgment on the merit of the book review and wonders if the 'book review' should go to another reviewer for a peer review. Another problem is, to the editor, the authors are the only accessible people who are knowledgeable about the subject matter of the book . Do you think it is okay to request the author/s to review the book review ?
