Information on Wikipedia must be reliable and verifiable.

Facts, viewpoints, theories, and opinions may only be used 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 most important parts of a Wikipedia article 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 refer directly to the claims made; for example, strong claims need very strong sources. If you are not sure if your sources are good enough, look at Wikipedia:Reliable sources, and if you're still not sure, you can ask the Reliable Sources Noticeboard for advice.

  • Do not use other Wikipedia articles as sources (though you can of course copy relevant sources from other Wikipedia articles).
  • Do not include your own opinions or experience.
