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.
This notability guideline for biographies reflects consensus reached through discussions and reinforced by established practice, and informs decisions on whether an article about a person should be written, merged, deleted or further developed. For advice about how to write biographical articles, see Wikipedia:Manual of Style (biographies) and Wikipedia:Biographies of living persons.
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 subject of a notable murder, then a title such as Murder of Kitty Genovese is appropriate.
