creative nonfiction and literary journalism use the power of language and literary devices more akin to fiction to bring insight and depth into the often book-length treatment of the subjects about which they write. such devices as dialogue, metaphor, digression and other such techniques offer the reader insights not usually found in standard news reportage. however, authors in this branch of journalism still maintain ethical criteria such as factual and historical accuracy as found in standard news reporting. they venture outside the boundaries of standard news reporting in offering richly detailed accounts. one widely regarded author in the genre is joyce carol oates, as with her book on boxer mike tyson.
