Non-fiction is one of the two main divisions in writing, the other form being fiction. Non-fiction is a story based on real facts and information . Non-fiction is a narrative, account, or other communicative work whose assertions and descriptions are believed by the author to be factual. These assertions and descriptions may or may not be accurate, and can give either a true or a false account of the subject in question, however, it is generally assumed that authors of such accounts believe them to be truthful at the time of their composition or, at least, pose them to their audience as historically or empirically true. Reporting the beliefs of others in a non-fiction format is not necessarily an endorsement of the ultimate veracity of those beliefs, it is simply saying it is true that people believe them (for such topics as mythology, religion). Non-fiction can also be written about fiction, giving information about these other works. Non-fiction need not necessarily be written text, since pictures and film can also purport to present a factual account of a subject.
Essays, journals, memoir, diaries, documentaries,], scientific papers, photographs, biographies, textbooks, travel books, blueprints, technical documentation, user manuals, diagrams and some journalism are all common examples of non-fiction works, and including information that the author knows to be untrue within any of these works is usually regarded as dishonest. Other works can legitimately be either fiction or non-fiction, such as journals of self-expression, letters, magazine articles, and other expressions of imagination. Though they are mostly either one or the other, it is possible for there to be a blend of both. Some fiction may include non-fictional elements. Some non-fiction may include elements of unverified supposition, deduction, or imagination for the purpose of smoothing out a narrative, but the inclusion of open falsehoods would discredit it as a work of non-fiction. The publishing and bookselling business sometimes uses the phrase "literary nonfiction" to distinguish works with a more literary or intellectual bent, as opposed to the greater collection of nonfiction subjects.
