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; for example, outlandish claims need very strong sources. If you're not sure if your sources are good enough, look at Wikipedia:Reliable sources, and if you're still not sure, you can ask at the Reliable Sources Noticeboard.
Note: other Wikipedia articles are not reliable sources (though you can of course copy relevant sources from other Wikipedia articles).
Good 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 may be deleted.
