Notability

WP:GNG (meet all criteria)

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 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.
- WP:SIGCOV
"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, 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" 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. 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.

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

WP:NBIO

On Wikipedia, notability is a test used by editors to decide whether a given topic warrants its own article. For people, the person who is the topic of a biographical article should be "worthy of notice" or "note"—that is, "remarkable" or "significant, interesting, or unusual enough to deserve attention or to be recorded" within Wikipedia as a written account of that person's life. "Notable" in the sense of being famous or popular—although not irrelevant—is secondary.

People are presumed notable if they have received significant coverage in multiple published secondary sources that are reliable, intellectually independent of each other, and independent of the subject.

If the depth of coverage in any given source is not substantial, then multiple independent sources may be combined to demonstrate notability; trivial coverage of a subject by secondary sources is not usually sufficient to establish notability.
Primary sources may be used to support content in an article, but they do not contribute toward proving the notability of a subject.

People who meet the basic criteria may be considered notable without meeting the additional criteria below. Articles may still not be created for such people if they fall under exclusionary criteria, such as being notable only for a single event, or such as those listed in Wikipedia:What Wikipedia is not.

WP:NARTIST (meet any criterion)

This guideline applies to authors, editors, journalists, filmmakers, photographers, artists, architects, and other creative professionals. Such a person is notable if:

The person is regarded as an important figure or is widely cited by peers or successors; or
The person is known for originating a significant new concept, theory, or technique; or
The person has created or played a major role in co-creating a significant or well-known work or collective body of work. In addition, such work must have been the primary subject of multiple independent periodical articles or reviews, or of an independent and notable work (for example, a book, film, or television series, but usually not a single episode of a television series); or
The person's work (or works) has: (a) become a significant monument, (b) been a substantial part of a significant exhibition, (c) won significant critical attention, or (d) been represented within the permanent collections of several notable galleries or museums.

WP:NFILM

One of the general notability guideline's criteria is that coverage should come from reliable sources that are independent of the subject. This section discusses a source's independence and reliability.

Independence: The source needs to be independent of the topic, meaning that the author and the publisher are not directly associated with the topic. Authors should not include members of the production, and publishers should not include the studio or companies working with it on the production and release. The kinds of sources that are considered independent are those that have covered topics unrelated to the one at hand, such as periodicals. Books that discuss a film in a larger context or among other films are also potential sources; see this section's last paragraph regarding the amount of coverage in a source. Press releases, even if they are reprinted by sources unrelated to the production, are not considered independent.
Reliability: The content guideline to identify reliable sources says, "Reliable sources may be published materials with a reliable publication process, authors who are regarded as authoritative in relation to the subject, or both." Sources that have published materials in print (such as newspapers and other periodicals) are reliable if their publication process is considered reliable. If these sources also publish materials online, then it is usually fair to assume that these materials have a similar publication process (see WP:NEWSBLOG). If sources publish materials only online, then their publication process and/or the authority of the author should be scrutinized carefully. Note should be taken that IMDb is not considered a reliable source for proving notability.

To presume notability, reliable sources should have significant coverage.

Some films that do not pass the above tests may still be notable, and should be evaluated on their own merits. The article's ability to attest to a film's notability through verifiable sources is significant. Some inclusionary criteria to consider are:

The film represents a unique accomplishment in cinema, is a milestone in the development of film art, or contributes significantly to the development of a national cinema, with such verifiable claims as "The only cel-animated feature film ever made in Thailand" (See The Adventure of Sudsakorn)
The film features significant involvement (i.e., one of the most important roles in the making of the film) by a notable person and is a major part of their career.
- An article on the film should be created only if there is enough information on it that it would clutter up the biography page of that person if it was mentioned there.
The film was successfully distributed domestically in a country that is not a major film producing country, and was produced by that country's equivalent of a "major film studio". Articles on such a film should assert that the film in question was notable for something more than merely having been produced, and if any document can be found to support this, in any language, it should be cited.

WP:NMUSIC

Musicians or ensembles (this category includes bands, singers, rappers, orchestras, DJs, musical theatre groups, instrumentalists, etc.) may be notable if they meet at least one of the following criteria.

Note that regardless of what notability criterion is being claimed, the claim must be properly verified by reliable sources independent of the subject's own self-published promotional materials. It is extremely common for aspiring musicians who want a Wikipedia article for the publicity to make inflated or false notability claims, such as charting hits that did not really chart (or which charted only on a non-notable WP:BADCHART) or nominations for awards that are not prominent enough to pass criterion number 8 (below). Thus, notability is not determined by what the article says, it is determined by how well the article does or does not support the things it says by referencing them to independent verification in reliable sources.

Has been the subject of multiple, non-trivial, published works appearing in sources that are reliable, not self-published, and are independent of the musician or ensemble itself.
- This criterion includes published works in all forms, such as newspaper articles, books, magazine articles, online versions of print media, and television documentaries except for the following:
  - Any reprints of press releases, other publications where the musician or ensemble talks about themselves, and all advertising that mentions the musician or ensemble, including manufacturers' advertising.
  - Articles in a school or university newspaper (or similar), in most cases.
Has had a single or album on any country's national music chart.
Has had a record certified gold or higher in at least one country.
Has received non-trivial coverage in independent reliable sources of an international concert tour, or a national concert tour in at least one sovereign country.
Has released two or more albums on a major record label or on one of the more important indie labels (i.e., an independent label with a history of more than a few years, and with a roster of performers, many of whom are independently notable).
Is an ensemble that contains two or more independently notable musicians, or is a musician who has been a reasonably prominent member of two or more independently notable ensembles. This should be adapted appropriately for musical genre; for example, having performed two lead roles at major opera houses. Note that this criterion needs to be interpreted with caution, as there have been instances where this criterion was cited in a circular manner to create a self-fulfilling notability loop (e.g., musicians who were "notable" only for having been in two bands, of which one or both were "notable" only because those musicians had been in them.)
Has become one of the most prominent representatives of a notable style or the most prominent of the local scene of a city; note that the subject must still meet all ordinary Wikipedia standards, including verifiability.
Has won or been nominated for a major music award, such as a Grammy, Juno, Mercury, Choice or Grammis award. Note that this requires the person or band to have been the direct recipient of a nomination in their own name, and is not passed by playing as a session musician on an album whose award citation was not specifically for that person's own contributions.
Has won first, second, or third place in a major music competition.
Has performed music for a work of media that is notable, such as a theme for a network television show, performance in a television show or notable film, inclusion on a notable compilation album. (But if this is the only claim, it is probably more appropriate to have a mention in the main article and redirect to that article. Read the policy and notability guideline on subjects notable only for one event, for further clarifications).
Has been placed in rotation nationally by a major radio or music television network.
Has been a featured subject of a substantial broadcast segment across a national radio or television network.

WP:ORGCRIT

A company, corporation, organization, group, product, or service is presumed notable if it has been the subject of significant coverage in multiple reliable secondary sources that are independent of the subject.

These criteria, generally, follow the general notability guideline with a stronger emphasis on quality of the sources to prevent gaming of the rules by marketing and public relations professionals. The guideline, among other things, is meant to address some of the common issues with abusing Wikipedia for advertising and promotion. As such, the guideline establishes generally higher requirements for sources that are used to establish notability than for sources that are allowed as acceptable references within an article.

How to apply the criteria[edit]

WP:SIRS

Individual sources must be evaluated separately and independently of each other and meet the four criteria below to determine if a source qualifies towards establishing notability:

Contain significant coverage addressing the subject of the article directly and in depth.
Be completely independent of the article subject.
Meet the standard for being a reliable source.
Be a secondary source; primary and tertiary sources do not count towards establishing notability.

An individual source must meet all of these criteria to be counted towards establishing notability; each source needs to be significant, independent, reliable, and secondary. In addition, there must also be multiple such sources to establish notability. If the suitability of a source is in doubt, it is better to exercise caution and exclude the source for the purposes of establishing notability.
