Memoirs and autobiographies are important forms of creative non-fiction. While both tell the true story of one's life, they do so in different ways. Memoirs may be written in vignettes or chapters illustrating random memories, while autobiographies are more linear. Autobiographies tend to reveal the life of a person in chronological order, while memoirs often show glimpses here and there. These two forms of book creatively tell a truthful tale.
Literary journalism, according to the University of Idaho, is a major sub-genre of creative non-fiction. Straight journalism is factual, which doesn't apply to creative non-fiction. However, while literary journalism is more creative and uses literary narrative techniques it is still journalism, truthfully describing real events and facts. Literary journalism often includes features and first-person perspectives about travel, food or cultural events. The journalist usually tells of his experience while relaying information about the location, or food, or event discussed.
Books that provide an introspective approach about a real event or place are often considered creative non-fiction. The website Creative Nonfiction uses the example of both "Death in the Afternoon" and "Down and Out in Paris and London" as good creative non-fiction books. The site states that the books look at poverty and society through an informative lens while also providing a personal edge.
