Information on Wikipedia must be reliable and verifiable.
Facts, viewpoints, theories, and arguments may only be included in articles if they have already been published by reliable and reputable sources. Sources should have a reputation for fact-checking and accuracy, and be independent of the subject. Citing sources is one of the core elements of Wikipedia and is official policy for every article on Wikipedia. Any unsourced material may be challenged and removed. For academic subjects, the sources should preferably be peer reviewed. Sources should also be appropriate to the claims made; outlandish claims need strong sources.
- have a reputation for reliability: they are reliable sources
- are independent of the subject
- are verifiable by other editors
If your article does not cite reliable, independent sources, it will almost certainly be deleted.
