This page documents an English Wikipedia notability guideline.

Editors should generally follow it, though exceptions may apply. Substantive edits to this page should reflect consensus. When in doubt, discuss first on this guideline's talk page.

Shortcuts

This page in a nutshell: If a topic has received significant coverage in reliable secondary sources that are independent of the subject, it is presumed to satisfy the inclusion criteria for a stand-alone article.

Not to be confused with WP:CITE, WP:FOOT, WP:NOT, or WP:Not Now. "WP:NOTE" and "WP:NN" redirect here.

Within Wikipedia, notability refers to whether or not a topic merits its own article at Wikipedia. Article topics of need to be notable, or "worthy of notice." It is important to note that topic notability on Wikipedia is not necessarily dependent on qualities like fame, importance, or popularity, although they may contribute.

A topic is presumed to be notable enough to merit an article if it meets the general notability guidelines below. A topic can also be considered notable if it meets the criteria outlined in one of the the more subject-specific guidelines: Academics, Books, Films, Music, Numbers, Organizations & companies, People, and Web content.

If an article currently does not cite reliable secondary sources, that does not necessarily mean that its topic is not notable.

These notability guidelines only outline how suitable a topic is for its own article. They don't directly limit the content of articles. 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

Shortcut

WP:GNG

If a topic has received significant coverage in reliable sources that are independent of the subject, it is presumed to satisfy the inclusion criteria for a stand-alone article.

"Significant coverage" means that sources address the subject directly in detail, and no original research is needed to extract the content. Significant coverage is more than trivial but may be less than exclusive.^[1]
"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. Availability of secondary sources covering the subject is a good test for notability.^[2]
"Sources,"^[3] for notability purposes, should be secondary sources, as those provide the most objective evidence of notability. The number and nature of reliable sources needed varies depending on the depth of coverage and quality of the sources. Multiple sources are generally preferred.^[4]
"Independent of the subject" excludes works produced by those affiliated with the subject including (but not limited to): self-publicity, advertising, self-published material by the subject, autobiographies, press releases, etc.^[5]
"Presumed" means that substantive coverage in reliable sources establishes a presumption, not a guarantee, of notability. Editors may reach a consensus that although a topic meets this criterion, it is not suitable for inclusion. For example, it may violate what Wikipedia is not.^[6]

A topic for which this criterion is deemed to have been met by consensus, is usually worthy of notice, and satisfies one of the criteria for a stand-alone article in the encyclopedia. Verifiable facts and content not supported by multiple independent sources may be appropriate for inclusion within another article.

Notability requires objective evidence

Shortcuts

The common theme in the notability guidelines is the requirement for verifiable objective evidence to support a claim of notability. Substantial coverage in reliable sources constitutes such objective evidence, as do published peer recognition and the other factors listed in the subject specific guidelines.

Wikipedia is not a news source: it takes more than just a short burst of news reports about a single event or topic to constitute evidence of sufficient notability. The Wikimedia project Wikinews covers topics of present news coverage.

Articles not satisfying the notability guidelines

Shortcut

WP:FAILN

Although articles should demonstrate the notability of their topics, and articles on topics that do not meet this criterion are generally deleted, it is important to not just consider whether notability is established by the article, but whether it readily could be. Remember that all Wikipedia articles are not a final draft, and an article can be notable if such sources exist even if they have not been added at present. Merely asserting that such sources exist is seldom persuasive, especially as time passes and actual proof does not surface. If it is likely that significant coverage in independent sources can be found for a topic, deletion due to lack of notability is inappropriate unless active effort has been made to find these sources. For articles of unclear notability, deletion should be a last resort.

If an article fails to cite sufficient sources to demonstrate the notability of its subject, look for sources yourself, or:

Ask the article's creator or an expert on the subject^[7] for advice on where to look for sources.
Put the {{notability}} tag on the article to alert other editors.
If the article is about a specialized field, use the {{expert-subject}} tag with a specific WikiProject to attract editors knowledgeable about that field, who may have access to reliable sources not available online.

If appropriate sources cannot be found after a good-faith search for them, consider merging the article's content into a broader article providing context.^[8] Otherwise, if deleting:^[9]

If the article meets our criteria for speedy deletion, one can use a criterion-specific deletion tag listed on that page.
Use the {{prod}} tag, for articles which do not meet the criteria for speedy deletion, but are uncontroversial deletion candidates. This allows the article to be deleted after five days if nobody objects. For more information, see Wikipedia:Proposed deletion.
For cases where you are unsure about deletion or believe others might object, nominate the article for the articles for deletion process, where the merits will be debated and deliberated for five days.

Notability is not temporary

Shortcuts

If a subject has met the general notability guideline, there is no need to show continual coverage or interest in the topic, though subjects that do not meet the guideline at one point in time may do so as time passes and more sources come into existence. However, articles should not be written based on speculation that the topic may receive additional coverage in the future.

Notability of article content

Shortcuts

The notability guidelines determine whether a topic is notable enough to be a separate article in Wikipedia. Notability, in the sense used to determine article inclusion, does not directly affect article content.

But the term "notability" is still used in the sense of "importance" to describe the level of detail that is appropriate for an encyclopedic summary. Treat each aspect with a weight appropriate to its significance to the subject. Attend to anything that may construe undue weight, including depth of detail, quantity of text, prominence of placement, and juxtaposition of statements. Keep in mind that an encyclopedia article is a summary of accepted knowledge regarding its subject, not a complete exposition of all possible details. For example, the notability guideline for people states that lists of people are not meant to be exhaustive.

Article content is also governed by various content policies.

Notes

^ Examples: The 360-page book by Sobel and the 528-page book by Black on IBM are plainly non-trivial. The one sentence mention by Walker of the band Three Blind Mice in a biography of Bill Clinton (Martin Walker (1992-01-06). "Tough love child of Kennedy". The Guardian. {{cite news}}: Check date values in: |date= (help)) is plainly trivial.
^ Self-promotion, autobiography, and product placement are not the routes to having an encyclopedia article. The published works should be someone else writing independently about the topic. The barometer of notability is whether people independent of the topic itself (or of its manufacturer, creator, author, inventor, or vendor) have actually considered the topic notable enough that they have written and published non-trivial works of their own that focus upon it. Otherwise, someone could give their own topic as much notability as they want by simply expounding on it outside of Wikipedia, which would defeat the purpose of the concept. Also, neutral sources should exist in order to guarantee a neutral article can be written — self-promotion is not neutral (obviously), and self-published sources often are biased if even unintentionally: see Wikipedia:Autobiography and Wikipedia:Conflict of interest for discussion of neutrality concerns of such sources. Even non-promotional self-published sources, in the rare cases they may exist, are still not evidence of notability as they do not measure the attention a subject has received by the world at large.
^ Including but not limited to newspapers, books and e-books, magazines, television and radio documentaries, reports by government agencies, scientific journals, etc. In the absence of multiple sources, it must be possible to verify that the source reflects a neutral point of view, is credible and provides sufficient detail for a comprehensive article.
^ Lack of multiple sources suggests that the topic may be more suitable for inclusion in an article on a broader topic. Mere republications of a single source or news wire service do not always constitute multiple works. Several journals simultaneously publishing articles in the same geographic region about an occurrence, does not always constitute multiple works, especially when the authors are relying on the same sources, and merely restating the same information. Specifically, several journals publishing the same article within the same geographic region from a news wire service is not a multiplicity of works.
^ Works produced by the subject, or those with a strong connection to them, are unlikely to be strong evidence of interest by the world at large. See also: Wikipedia:Conflict of interest for handling of such situations.
^ Moreover, not all coverage in reliable sources constitutes evidence of notability for the purposes of article creation; for example, directories and databases, advertisements, announcements columns, and minor news stories are all examples of coverage that may not actually support notability when examined, despite their existence as reliable sources.
^ Sometimes contacting the subject of a biography or the representative of a subject organization will yield independent source material. Of course we have to be careful to observe and evaluate independence. You might also see if there is a wikipedia project related to the topic, and ask for help there.
^ For instance, articles on minor characters in a work of fiction may be merged into a "list of minor characters in ..."; articles on schools may be merged into articles on the towns or regions where schools are located; relatives of a famous person may be merged into the article on the person; articles on persons only notable for being associated with a certain group or event may be merged into the main article on that group or event.
^ Wikipedia editors have been known to reject nominations for deletion that have been inadequately researched. Research should include attempts to find sources which might demonstrate notability, and/or information which would demonstrate notability in another manner.
