Wikipedia:Citing Wikipedia

We advise special caution when using Wikipedia as a source for research projects. Normal academic usage of Wikipedia is for getting the general facts of a problem and to gather keywords, references and bibliographical pointers, but not as a source in itself. Remember that Wikipedia is a wiki. Anyone in the world can edit an article, deleting accurate information or adding false information, which the reader may not recognize. Thus, you probably shouldn't be citing Wikipedia. This is good advice for all tertiary sources such as encyclopedias, which are designed to introduce readers to a topic, not to be the final point of reference. Wikipedia, like other encyclopedias, provides overviews of a topic and indicates sources of more extensive information. See researching with Wikipedia and academic use of Wikipedia for more information.

If you do decide to cite Wikipedia, remember that its articles are constantly changing: cite exact time, date, and the article version you are using. Page history and toolbox features "cite this article" and "permanent link" are very useful for finding that information.

If you decide to quote or paraphrase Wikipedia text (despite all the warnings above applying to the information in Wikipedia), then you must cite Wikipedia appropriately; otherwise you plagiarise, which is against academic norms and may subject you to censure. Such failure also violates Wikipedia's CC BY-SA copyright license, which is a violation of copyright law.
