List of policies and guidelines

Wikipedia articles should be based on reliable, published sources; and, all majority and significant minority views that appear in these sources should be covered by these articles (see Wikipedia:Neutral point of view). The word "source" as used on Wikipedia has three related meanings: the piece of work itself (the article, book), the creator of the work (the writer, journalist), and the publisher of the work (for example The New York Times, Cambridge University Press, etc.). All three can affect reliability. Reliable sources may be published materials with a reliable publication process, authors who are regarded as authoritative in relation to the subject, or both.

The reliability of a source depends on context. Each source must be carefully weighed to judge whether it is reliable for the statement being made and is the best such source for that context. In general, the more people engaged in checking facts, analyzing legal issues, and scrutinizing the writing, the more reliable the publication. Sources should directly support the information as it is presented in an article, and should be appropriate to the claims made. If a topic has no reliable sources, Wikipedia should not have an article on it.

This guideline discusses the reliability of various types of sources. The policy on sourcing is Wikipedia:Verifiability, which requires inline citations for any material challenged or likely to be challenged, and for all quotations. The policy is strictly applied to all material in the mainspace—articles, lists, and sections of articles—without exception, and in particular to biographies of living persons, which states:

Contentious material about living persons that is unsourced or poorly sourced—whether the material is negative, positive, neutral, or just questionable—should be removed immediately and without waiting for discussion.

In the event of a contradiction between this page and our policies regarding sourcing and attribution, the policy takes priority and editors should seek to resolve the discrepancy. Other policies relevant to sourcing are Wikipedia:No original research and Wikipedia:Biographies of living persons. For questions about the reliability of particular sources, see Wikipedia:Reliable sources/Noticeboard.
