The goal of a Wikipedia article is to create a comprehensive and neutrally written summary of existing mainstream knowledge about a topic. Accordingly, Wikipedia does not publish original research. An encyclopedia is, by its nature, a tertiary source that provides a survey of information already the subject of publication in the wider world. Accordingly, and because Wikipedia is open to editing by anyone, we require that information be verifiable in reliable sources. Ideally all information should be actually cited to reliable sources to evidence it is verifiable. When adding content and creating new articles an encyclopedic style with a formal tone is important. Instead of essay-like, argumentative, or opinionated writing, Wikipedia articles should have a straightforward, just-the-facts style.
