What sources do you need before creating a Wikipedia page?

The sourcing requirement for a new article is the threshold above which the article is likely to survive community review and Articles for Deletion processes. The practical minimum is three to five substantial independent pieces from outlets that meet Wikipedia’s reliable-source standard, with each piece covering the subject directly and in depth rather than mentioning it in passing inside a story about something else. Quality matters as much as quantity: a single in-depth Bloomberg profile carries more weight than five trade-publication briefs. Complex or controversial subjects need more (often ten or more substantial pieces) because the article will attract scrutiny and the sources need to support the full range of content the article will contain. Press releases, sponsored content, wire-service syndications of company announcements, and the company’s own materials do not count toward this requirement regardless of where they appeared. We catalog the existing record against this standard during the readiness assessment.
