Wikipedia is an encyclopaedia, and the community constantly strives for accuracy. Articles should be neutral and should contain only verifiable information and opinions that already exist in reliable sources.
 |
Neutral point-of-view (or NPOV) means that content is written objectively and without bias, merely presenting the facts and notable viewpoints of others. A general-purpose encyclopedia ought not contain articles that favor particular viewpoints. Striving for a neutral point-of-view helps prevent articles from becoming advertisements or propaganda.

Verifiability means that articles should contain only material that has been published by reliable sources, such as reputable newspapers and scholarly journals. All content should ideally be supported by a citation, but content that is controversial or likely to be challenged will definitely require one! Unsourced material may be removed at any time, and it is the obligation of the editor adding material to provide a reliable source. |
 |
No original research means that articles may not contain previously unpublished arguments, concepts, data, opinions, or theories. This prohibition means that Wikipedia editors' own analysis or synthesis should not be included in articles. Basically, Wikipedia is a record of human knowledge, viewpoints, and summaries that already exist and are expressed elsewhere. |
