Non-fiction (or nonfiction) is any document or media content that attempts, in good faith, to convey information only about the real world, rather than being grounded in imagination. Non-fiction typically aims to present topics objectively based on historical, scientific, and empirical information. However, some non-fiction ranges into more subjective territory, including sincerely held opinions on real-world topics. Often referring specifically to prose writing, non-fiction is one of the two fundamental approaches to story and storytelling, in contrast to narrative fiction, which is largely populated by imaginary characters and events. Non-fiction writers can show the reasons and consequences of events, they can compare, contrast, classify, categorise and summarise information, put the facts in a logical or chronological order, infer and reach conclusions about facts, etc. They can use graphic, structural and printed appearance features such as pictures, graphs or charts, diagrams, flowcharts, summaries, glossaries, sidebars, timelines, table of contents, headings, subheadings, bolded or italicised words, footnotes, maps, indices, labels, captions, etc. to help readers find information. While specific claims in a non-fiction work may prove inaccurate, the sincere author aims to be truthful at the time of composition. A non-fiction account is an exercise in accurately representing a topic, and remains distinct from any implied endorsement. Source: Wikipedia (en)
