Information on Wikipedia must be reliable and verifiable.
Facts, opinions, theories and arguments may only be included in articles if they have already been published by reliable sources. Sources you use should have a reputation for accuracy, and should not be associated with the subject. Citing sources is one of the main duties of Wikipedia and is an official rule for every article on Wikipedia. Any material that is not sourced may be challenged and removed by another editor. Reading Wikipedia:Reliable sources will give you an idea about whether your sources are good enough. If you are still not sure, you can ask at Simple talk.
Note: other Wikipedia articles are not reliable sources (though you can of course copy related sources from other Wikipedia articles).
- have a reputation for being reliable
- are independent of the subject
- can be verified by other editors
