On Wikipedia, notability is a test used by editors to decide whether a given topic warrants its own article.

Information on Wikipedia must be verifiable; if no reliable third-party sources can be found on a topic, then it should not have a separate article. Wikipedia's concept of notability applies this basic standard to avoid indiscriminate inclusion of topics. Article and list topics must be notable, or "worthy of notice". Determining notability does not necessarily depend on things such as fame, importance, or popularity—although those may enhance the acceptability of a subject that meets the guidelines explained below.

A topic is presumed to merit an article if:

  1. It meets either the general notability guideline below, or the criteria outlined in a subject-specific guideline listed in the box on the right; and
  2. It is not excluded under the What Wikipedia is not policy.

This is not a guarantee that a topic will necessarily be handled as a separate, stand-alone page. Editors may use their discretion to merge or group two or more related topics into a single article. These guidelines only outline how suitable a topic is for its own article or list. They do not limit the content of an article or list. For Wikipedia's policies regarding content, see Neutral point of view, Verifiability, No original research, What Wikipedia is not, and Biographies of living persons.

General notability guideline

If a topic has received significant coverage in reliable sources that are independent of the subject, it is presumed to be suitable for a stand-alone article or list.

  • "Significant coverage" addresses the topic directly and in detail, so that no original research is needed to extract the content. Significant coverage is more than a trivial mention, but it does not need to be the main topic of the source material.
    • The book-length history of IBM by Robert Sobel is plainly non-trivial coverage of IBM.
    • Martin Walker's statement, in a newspaper article about Bill Clinton, [1] that "In high school, he was part of a jazz band called Three Blind Mice" is plainly a trivial mention of that band.
  • "Reliable" means sources need editorial integrity to allow verifiable evaluation of notability, per the reliable source guideline. Sources may encompass published works in all forms and media, and in any language. Availability of secondary sources covering the subject is a good test for notability.
  • "Sources" [2] should be secondary sources, as those provide the most objective evidence of notability. There is no fixed number of sources required since sources vary in quality and depth of coverage, but multiple sources are generally expected. [3] Sources do not have to be available online or written in English. Multiple publications from the same author or organization are usually regarded as a single source for the purposes of establishing notability.
  • "Independent of the subject" excludes works produced by the article's subject or someone affiliated with it. For example, advertising, press releases, autobiographies, and the subject's website are not considered independent. [4]
  • "Presumed" means that significant coverage in reliable sources creates an assumption, not a guarantee, that a subject should be included. A more in-depth discussion might conclude that the topic actually should not have a stand-alone article—perhaps because it violates what Wikipedia is not, particularly the rule that Wikipedia is not an indiscriminate collection of information.

If a topic does not meet these criteria but still has some verifiable facts, it might be useful to discuss it within another article.
