Reliable sources
Any material that is challenged or likely to be challenged must be accompanied by a reliable source. Material that counts as "original research" within the meaning of this policy is material for which no reliable source can be found and which is therefore believed to be the original thought of the Wikipedian who added it. The only way to show that your work is not original research is to produce a reliable published source that advances the same claims or makes the same argument as you.

In general, the most reliable sources are books, journals, magazines, and mainstream newspapers; published by university presses or known publishing houses. As a rule of thumb, the more people engaged in checking facts, analyzing legal issues, and scrutinizing the writing, the more reliable the publication. Material that is self-published, whether on paper or online, is generally not regarded as reliable, but see Verifiability for exceptions.

Secondary and tertiary sources should be used in a way that does not give rise to new analysies, syntheses or original conclusions that are not already present in the sources. In short, the policy of "No original research" requres that wikipedia users stick to the sources.
