Wikipedia:The answer to life, the universe, and everything

We need sources that provide significant coverage. Usually this means discussion of the subject directly and in detail, with some sort of analysis, critique, or debate. Not: passing mentions, directory or database listings, or government records.

We usually need more than one distinct source discussing the subject. There is no fixed number, but the sources should be distinct and provide separate coverage, rather than just repeating the same information.

We need sources that are reliable. Usually this means that the publisher has a reputation for fact-checking, editorial oversight, and accuracy. For example: books from reputable publishing houses, mainstream newspapers, academic journals, magazines, and other established publications. Not: tabloids, discussion boards, fansites, social media, and most self-published blogs.

We need sources that are independent of the subject of the article. This means not connected or influenced by the subject. Not: books or articles written by the subject, material paid for or commissioned by the subject, press releases, churnalism, or interviews where virtually all of the information comes from the subject or their spokesperson.
