Wikipedia:Notability
This page documents an English Wikipedia consensus. When in doubt, discuss first on this guideline's talk page. |
This page in a nutshell: Wikipedia articles cover notable topics—those that have gained sufficiently significant attention by the world at large and over a period of time, and are reliable and independent sources to gauge this attention. The notability guideline does not determine the content of articles, but only whether the topic may have its own article. |
On Wikipedia, notability is a test used by editors to decide whether a given topic warrants its own article.
Information on Wikipedia must be
A topic is presumed to merit an article if:
- It meets either the general notability guideline (GNG) below, or the criteria outlined in a subject-specific notability guideline (SNG); and
- 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
General notability guideline
A topic is presumed to be suitable for a stand-alone article or list when it has received significant coverage in reliable sources that are independent of the subject.
- "Presumed" means that significant coverage in Wikipedia is not an indiscriminate collection of information.[1]
- "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,[2] 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 that sources need editorial integrity to allow in any language. Availability of secondary sources covering the subject is a good test for notability.
- "Sources"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.[5]
If a topic does not meet these criteria but still has some verifiable facts, it might be useful to discuss it within another article.
Subject-specific notability guidelines
In some topic areas, subject-specific notability guidelines (SNGs) have been written to help clarify when a standalone article can or should be written. The currently accepted subject guidelines are listed in the box at the top of this page and at Category:Wikipedia notability guidelines. Wikipedia articles are generally written based on in-depth, independent, reliable sourcing with some subject-specific exceptions. The subject-specific notability guidelines generally include verifiable criteria about a topic which show that appropriate sourcing likely exists for that topic. Therefore, topics which pass an SNG are presumed to merit an article, though articles which pass an SNG or the GNG may still be deleted or merged into another article, especially if adequate sourcing or significant coverage cannot be found, or if the topic is not suitable for an encyclopedia.
SNGs also serve additional and varying purposes depending on the topic. Some SNGs, for example the ones in the topic areas of
Some WikiProjects have provided additional guidance on notability of topics within their field. Editors are cautioned that these WikiProject notability guidance pages should be treated as essays and do not establish new notability standards, lacking the weight of broad consensus of the general and subject-specific notability guidelines in various discussions (such as at Wikipedia:Articles for deletion).
Notability guidelines do not apply to content within articles or lists
The criteria applied to the creation or retention of an article are not the same as those applied to the content inside it. The notability guideline does not apply to the contents of articles. It also does not apply to the contents of
Article content does not determine notability
Notability is a property of a subject and not of a Wikipedia article. If the subject has not been covered outside of Wikipedia,
Notability requires verifiable evidence
The common theme in the notability guidelines is that there must be verifiable, objective evidence that the subject has received significant attention from independent sources to support a claim of notability.
No subject is automatically or inherently notable merely because it exists: the evidence must show the topic has gained significant independent coverage or recognition, and that this was not a mere
Notability is based on the existence of suitable sources, not on the state of sourcing in an article
The absence of sources or citations in a Wikipedia article (as distinct from the non-existence of independent, published reliable sources in libraries, bookstores, and the internet) does not indicate that a subject is not notable. Notability requires only that suitable independent, reliable sources
Wikipedia articles are
Current state of the article | Sources available in the real world
|
Result |
---|---|---|
No or few suitable sources cited | No or few suitable sources that could be cited | Likely not notable |
Multiple suitable sources cited | Multiple suitable sources that could be cited | Likely notable |
No or few suitable sources cited | Multiple suitable sources that could be cited | Likely notable |
Notability is not temporary
Notability is not temporary; once a topic has been the subject of "significant coverage" in accordance with the general notability guideline, it does not need to have ongoing coverage.
While notability itself is not temporary, from time to time a reassessment of the evidence of notability or suitability of existing articles may be requested by any user via a deletion discussion, or new evidence may arise for articles previously deemed unsuitable. Thus, an article may be proposed for deletion months or even years after its creation, or recreated whenever new evidence supports its existence as a standalone article.
Notable topics have attracted attention over a sufficiently significant period of time
Wikipedia is a lagging indicator of notability. Just as a
If reliable sources cover a person only in the context of a single event, and if that person otherwise remains, and is likely to remain, a low-profile individual,
Whether to create standalone pages
When creating new content about a notable topic, editors should consider how best to help readers understand it. Often, understanding is best achieved by presenting the topic on a dedicated standalone page, but it is not required that we do so; at times it is better to cover a notable topic as part of a larger page about a broader topic, with more context (and doing so in no way disparages the importance of the topic). Editorial judgment goes into each decision about whether or not to create a separate page, but the decision should always be based upon specific considerations about how to make the topic understandable, and not merely upon personal
- Does other information provide needed context? Sometimes, a notable topic can be covered better as part of a larger article, where there can be more complete context that would be lost on a separate page (due and undue weight. Fringe theories, for example, may merit standalone pages but have undue weight on a page about the mainstream concept.
- Do related topics provide needed context? Sometimes, several related topics, each of them similarly notable, can be collected into a single page, where the relationships between them can be better appreciated than if they were each a separate page (as at Music of the Final Fantasy VII series). Other times, when many similar notable topics exist, it is impractical to collect them into a single page, because the resulting article would be too unwieldy. In that case, a viable option is creating a new list or category for the broader topic and linking to the individual articles from it (as with Category:Restaurants in New York City).
- What sourcing is available now? Sometimes, when a subject is notable, but it is unlikely that there ever will be a lot to write about it, editors should weigh the advantages and disadvantages of creating a a standalone article for a new film be createdonly if reliable sources confirm that principal photography for the film has commenced, as completion of the film is generally seen out to the end from this point on.
Why we have these requirements
Editors apply notability standards to all subjects to determine whether the English language Wikipedia should have a separate, stand-alone article on that subject. The primary purpose of these standards is to ensure that editors create articles that comply with major content policies.
- We require "significant coverage" in reliable sources so that we can actually write a whole article, rather than half a paragraph or a the advice below.)
- We require the existence of indiscriminate collections of information.
- We require that all articles rely primarily on not advertising a product, service, or organization. See Wikipedia:Autobiographyfor discussion of neutrality concerns of self-published sources.
- We require the existence of at least one secondary source so that the article can comply with Wikipedia:No original research's requirement that all articles be based on secondary sources.
- We require multiple sources so that we can write a reasonably balanced article that complies with Wikipedia:Neutral point of view, rather than representing only one author's point of view. This is also why multiple publications by the same person or organization are considered to be a single source for the purpose of complying with the "multiple" requirement.
- We require editors to use their judgment about how to organize subjects so that we have neither long, bloated articles nor WP:FAILN.)
Because these requirements are based on major content policies, they apply to all articles, not solely articles justified under the

Stand-alone lists
Notability guidelines also apply to the creation of stand-alone lists and tables. Notability of lists (whether titled as "List of Xs" or "Xs") is based on the group. One accepted reason why a list topic is considered notable is if it has been discussed as a group or set by independent reliable sources, per the above guidelines; and other guidelines on

Articles not satisfying the notability guidelines
Topics that do not meet this criterion are not retained as separate articles. Non-notable topics with closely related notable articles or lists are often merged into those pages, while non-notable topics without such merge targets are generally deleted.
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[8] for advice on where to look for sources.
- Place a {{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 sourcesnot available online.
If appropriate sources cannot be found after a good-faith search for them, consider merging the article's verifiable content into a broader article providing context.[9] Otherwise, if deleting:[10]
- 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 seven days if nobody objects. For more information, see Wikipedia:Proposed deletion.
- For cases where you are unsure about deletion, believe others might object, or another editor has already objected to a previous proposed deletion, nominate the article for the articles for deletion process, where the merits will be debated and deliberated for seven days.
For articles on subjects that are clearly not notable, then deletion is usually the most appropriate response, although other options may help the community to

- ^ Including but not limited to newspapers, books and e-books, magazines, television and radio documentaries, reports by government agencies, and academic journals. 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. It is common for multiple newspapers or journals to publish the same story, sometimes with minor alterations or different headlines, but one story does not constitute multiple works. Several journals simultaneously publishing different articles does not always constitute multiple works, especially when the authors are relying on the same sources, and merely restating the same information. Similarly, a series of publications by the same author or in the same periodical is normally counted as one source.
- ^ Works produced by the subject, or those with a strong connection to them, are unlikely to be strong evidence of notability. See also: Wikipedia:Verifiability § Questionable sources for handling of such situations.
