It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply. Any substantive edit to this page should reflect consensus. When in doubt, discuss first on the talk page.
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.
The article title should define what the article is about. If there is enough valid content to fill an article about a person, then that person's name (such as "John Doe" or "Jane Doe") would be an appropriate title. If, however, there is only enough information about one notable event related to the person, then the article should be titled specifically about that event, such as Steve Bartman incident. Sometimes when a famous person dies, there is enough information for an article about their death, such as Death of Michael Jackson or Death of Diana, Princess of Wales. If a notable person's main article is too long to contain all of their works, then a separate page can be created for that information, such as George Orwell bibliography. If the person was the victim of a notable murder, then a title such as Murder of Kitty Genovese is appropriate.
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 may not be 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.
