Wikipedia:Long-term Unsourced Articles

The purpose of this policy is to improve the overall reliability and accuracy of Wikipedia by automatically deleting articles which have remained unsourced for a long period of time, after a final warning period.

As stated in WP:Attribution, the threshold for inclusion in Wikipedia is whether material is attributable to a reliable published source. Properly sourced articles are critical to the reliability and accuracy of Wikipedia as a whole. When articles are created which lack proper sources, they may be tagged with notices such as {{Unsourced}} in order to notify editors to add proper sources. However, hundreds of articles exist that have not been edited more than a few times or in many months; these articles have fallen through the cracks. This issue has been a major issue and has led to numerous occurrences of negative media coverage. Articles that have remained unsourced for over 3 months should be placed in a status warning of imminent deletion in order to offer editors a final chance to source the article. After another 3 months those articles will be speedily deleted. Although some valid articles may be deleted, this process will ensure a higher reliability and accuracy of Wikipedia and also prevent articles from indefinitely having unsourced information which may be incorrect.
