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 the talk page.

Shortcuts WP:N WP:NN WP:NOTE

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 not outside the scope of Wikipedia. We consider evidence from reliable and independent sources to gauge this attention. The notability guideline does not determine the content of articles, but only whether the topic should 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 verifiable; if no reliable, independent 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, though notability is commonly used as an inclusion criterion for lists (for example for listing out a school's alumni). For Wikipedia's policies regarding content, see Neutral point of view, Verifiability, No original research, What Wikipedia is not, and Biographies of living persons.

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 that 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 merits its own article. 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.^[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.

In some topic areas, consensus-derived subject-specific notability guidelines (SNGs) have been written as alternative to the general notability guideline to allow for a standalone article. The currently-accepted subject-specific notability guidelines are listed in the box at the top of this page and listed at Category:Wikipedia notability guidelines. These subject-specific notability guidelines are generally derived based on verifiable criteria due to accomplishment or recognition in that field that either in-depth, independent sourcing likely exists for that topic but may take time and effort to locate (such as print works in libraries local to the topic), or that sourcing will likely be written for the topic in the future due to the strength of accomplishment (such as winning a Nobel prize). Thus, we allow for the standalone article on the presumption that meeting the SNG criteria will guarantee the existence or creation of enough coverage to meet GNG.

These are considered shortcuts to meeting the general notability guideline. A topic is not required to meet both the general notability guideline and a subject-specific notability guideline to qualify for a standalone article. Note, however, that in cases where GNG has not been met and a subject's claim to meeting an SNG is weak or subjective, the article may still be deleted or merged: a presumption is neither a guarantee that sources can be found nor a mandate for a separate page.

Note that in addition to providing criteria for establishing notability, some SNGs also add additional restrictions on what types of coverage can be considered for notability purposes. For example, the SNG for companies and organizations specifies a very strict set of criteria for sources being considered. SNGs may also include suggested alternatives to deletion in the event that a subject is not found to be notable.

Some WikiProjects have provided additional guidance on notability of topics within their field, such as WikiProject Military History notability guidance. 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 WP:AFD).

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 guidelines do not apply to contents of articles or lists (with the exception of lists which restrict inclusion to notable items or people). Content coverage within a given article or list (i.e. whether something is noteworthy enough to be mentioned within the article or list) is governed by the principle of due weight and other content policies. For additional information about list articles, see Notability of lists and List selection criteria.

Notability is a property of a subject and not of a Wikipedia article. If the subject has not been covered outside of Wikipedia, no amount of improvements to the Wikipedia content will suddenly make the subject notable. Conversely, if the source material exists, even very poor writing and referencing within a Wikipedia article will not decrease the subject's notability.

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 short-term interest, nor a result of promotional activity or indiscriminate publicity, nor is the topic unsuitable for any other reason. Sources of evidence include recognized peer-reviewed publications, credible and authoritative books, reputable media sources, and other reliable sources generally.

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 an article (as distinct from the non-existence of sources) does not indicate that a subject is not notable. Notability requires only the existence of suitable independent, reliable sources, not their immediate presence or citation in an article. Editors evaluating notability should consider not only any sources currently named in an article, but also the possibility or existence of notability-indicating sources that are not currently named in the article. Thus, before proposing or nominating an article for deletion, or offering an opinion based on notability in a deletion discussion, editors are strongly encouraged to attempt to find sources for the subject in question and consider the possibility of existent sources if none can be found by a search.

Wikipedia articles are not a final draft, and an article's subject can be notable if such sources exist, even if they have not been named yet. If it is likely that significant coverage in independent sources can be found for a topic, deletion due to lack of notability is inappropriate. However, once an article's notability has been challenged, merely asserting that unspecified sources exist is seldom persuasive, especially if time passes and actual proof does not surface.

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.

Wikipedia is a lagging indicator of notability. Just as a lagging economic indicator indicates what the economy was doing in the past, a topic is "notable" in Wikipedia terms only if the outside world has already "taken notice of it". Brief bursts of news coverage may not sufficiently demonstrate notability. However, sustained coverage is an indicator of notability, as described by notability of events. New companies and future events might pass WP:GNG, but lack sufficient coverage to satisfy WP:NOTNEWSPAPER, and these must still also satisfy WP:NOTPROMOTION.

If reliable sources cover a person only in the context of a single event, and if that person otherwise remains, or is likely to remain, a low-profile individual, we should generally avoid having a biographical article on that individual.

When creating new content about a notable topic, editors should consider how best to help readers understand it. Sometimes, understanding is best achieved by presenting the material on a dedicated standalone page, but it is not required that we do so. There are other times when it is better to cover notable topics, that clearly should be included in Wikipedia, as part of a larger page about a broader topic, with more context. A decision to cover a notable topic only as part of a broader page does not in any way disparage 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 likes or dislikes. Wikipedia is a digital encyclopedia, and so the amount of content and details should not be limited by concerns about space availability.

• 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 (Barack Obama presidential campaign, 2012#Other initiatives and Mitt Romney presidential campaign, 2012#International trip, for example). Other times, standalone pages are well justified (as with President of the United States as well as standalone biographies of every individual President). One should particularly consider 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 permanent stub. On the other hand, an article may be a stub even though many sources exist, but simply have not been included yet. Such a short page is better expanded than merged into a larger page (see also the essays Wikipedia:Every snowflake is unique and Wikipedia:Run-of-the-mill). Sometimes, when information about a future event is scarce, coverage may instead be better suited to a larger encompassing article (see also Wikipedia:CRYSTAL). Other times, a future event may clearly be suitable for a standalone page before it happens (such as the 2020 Summer Olympics). However, before creating such an article, make sure that the likelihood of the future event to happen is reasonably assured. For example, the WikiProject Film strongly recommends that a standalone article for a new film be created only when principle photography on the film can be affirmed, as films are generally seen out to the end from this point on.

Subject-specific notability guidelines and WikiProject advice pages may provide information on how to make these editorial decisions in particular subject areas. When a standalone page is created, it can be spun off from a broader page. Conversely, when notable topics are not given standalone pages, redirection pages and disambiguation can be used to direct readers searching for such topics to the appropriate articles and sections within them (see also Wikipedia:Redirects are cheap).

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 definition of that topic. If only a few sentences could be written and supported by sources about the subject, that subject does not qualify for a separate page, but should instead be merged into an article about a larger topic or relevant list. (See the advice below.)
• We require the existence of "reliable sources" so that we can be confident that we're not passing along random gossip, perpetuating hoaxes, or posting indiscriminate collections of information.
• We require that all articles rely primarily on "third-party" or "independent sources" so that we can write a fair and balanced article that complies with Wikipedia's neutral point of view policy and to ensure that articles are not advertising a product, service, or organization.
• 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 articles so narrow that they cannot be properly developed. Editors may decide that it is better for readers to present a narrow subject as part of a broader one. For example, editors normally prefer to merge information about translations of books into the larger subject of the original book, because in their editorial judgment, the merged article is more informative and more balanced for readers and reduces redundant information in the encyclopedia. (For ideas on how to deal with material that may be best handled by placing it in another article, see WP:FAILN.)

Because these requirements are based on major content policies, they apply to all articles, not solely articles justified under the general notability criteria. They do not, however, apply to pages whose primary purpose is navigation (e.g. all disambiguation pages and some lists).

Self-promotion and publicity

Publication in a reliable source is not always good evidence of notability. Wikipedia is not a promotional medium. Self-promotion, autobiography, product placement and most paid material are not valid routes to an encyclopedia article. 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—without incentive, promotion, or other influence by people connected to the topic matter.

Independent sources are also needed to guarantee a neutral article can be written; see Wikipedia:Autobiography for discussion of neutrality concerns of self-published sources. Even non-promotional self-published sources, like technical manuals that accompany a product, are still not evidence of notability as they are not a measure of the attention a subject has received.

Events

Wikipedia is not a news source: it takes more than just routine news reports about a single event or topic to constitute significant coverage. For example, routine news coverage such as press releases, public announcements, sports coverage, and tabloid journalism is not significant coverage. Even a large number of news reports that provide no critical analysis of the event is not considered significant coverage. The Wikimedia project Wikinews covers topics of present news coverage. In some cases, notability of a controversial entity (such as a book) could arise either because the entity itself was notable, or because the controversy was notable as an event—both need considering.

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; notable list topics are appropriate for a stand-alone list. The entirety of the list does not need to be documented in sources for notability, only that the grouping or set in general has been. Because the group or set is notable, the individual items in the list do not need to be independently notable, although editors may, at their discretion, choose to limit large lists by only including entries for independently notable items or those with Wikipedia articles.

There is no present consensus for how to assess the notability of more complex and cross-categorization lists (such as "Lists of X of Y") or what other criteria may justify the notability of stand-alone lists, although non-encyclopedic cross-categorizations are touched upon in Wikipedia:What Wikipedia is not. Lists that fulfill recognized informational, navigation, or development purposes often are kept regardless of any demonstrated notability. Editors are still urged to demonstrate list notability via the grouping itself before creating stand-alone lists.

Fringe topics

For guidance on fringe topics, see Wikipedia:Fringe theories.

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^[6] 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 sources not 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.^[7] Otherwise, if deleting:^[8]

• 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 preserve any useful material.
