Writing book reviews is a great way to develop your skills in non-fiction. Contact the book section editor for your local newspaper or for magazines you read to express interest in doing them. Include samples of any past publications you have. Once you receive an assignment, follow the guidelines for freelancers. Read articles on book reviewing to help you. Have an experienced writer or editor review your draft before submitting it. Keep a file of your published clips.
