The threshold for inclusion in Wikipedia is verifiability, not truth—that is, whether readers are able to check that material added to Wikipedia has already been published by a reliable source, not whether we think it is true. Editors should provide a reliable source for quotations and for any material that is challenged or likely to be challenged, or the material may be removed.TeapotgeorgeTalk 17:53, 12 January 2010 (UTC)
Providing references
editWelcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add content (particularly if you change facts and figures) please cite a reliable source for the content you're adding or changing. This helps maintain our policy of verifiability. Take a look at Wikipedia:Citing sources for information about how to cite sources and the welcome page to learn more about contributing to this encyclopedia. Thank you. --Deskford (talk) 18:03, 12 January 2010 (UTC)
