There is very little published literary criticism of creative nonfiction works, despite the fact that the genre is often published in respected publications such as The New Yorker , Vanity Fair , Harper's , and Esquire .  A handful of the most widely recognized writers in the genre such as Robert Caro , Gay Talese , Joseph Mitchell , Tom Wolfe , John McPhee , Joan Didion , John Perkins , Ryszard Kapuściński , Helen Garner and Norman Mailer have seen some criticism on their more prominent works. "Critics to date, however, have tended to focus on only one or two of each writer's works, to illustrate particular critical points."  These analyses of a few key pieces are hardly in-depth or as comprehensive as the criticism and analyses of their fictional contemporaries [ citation needed ] . As the popularity of the genre continues to expand, many nonfiction authors and a handful of literary critics are calling for more extensive literary analysis of the genre.
