Wikipedia:Help with sources
|This essay contains the advice or opinions of one or more Wikipedia users. Essays may represent common ideas, or ideas that many users would not support. They are not rules. Think carefully about what they say before following them.|
References that are about the subject – at least one paragraph, but it is better to have more. They should not be catalogues, directory listings, or just anything that happens to have the name in it. Several sources – not just one. It must be notable.
Something that is generally trusted to tell the truth. Examples are a major newspaper, a book that is factual, or a popular magazine or journal which is known for its accuracy. Blogs, MySpace, Facebook, forum/Usenet posts, fansites, or Twitter are not acceptable. It must be verifiable.
Nothing written by the subject, paid for or linked with the subject. It should not be their website, a press-release or a primary source.
