Deletion of articles on Wikipedia

Volunteer editors of Wikipedia delete articles from the online encyclopedia regularly, following processes that have been formulated by the site's community over time. The most common route is the outright deletion of articles that clearly violate the rules of the website (speedy deletion). Other mechanisms include an intermediate collaborative process that bypasses a complete discussion (proposed deletion or PROD), and a whole debate at the dedicated forum called Articles for deletion (AfD). As a technical action, deletion can only be done by a subset of editors assigned particular specialized privileges by the community, called administrators. An omission that has been carried out can be contested by appeal to the deleting administrator or on another discussion board called Deletion review (DRV).

Unless an administrator deletes an article on sight, the deletion process involves the addition of a template to the report by an editor, indicating to readers and other editors which kind of deletion process is sought for that article. Removing a template proposing speedy deletion or proposed deletion often precipitates a formal nomination for deletion through AfD. In contrast, removing an AfD template is not permitted until the discussion has concluded. When an article is deleted, the article's talk page is generally also deleted, as are links that redirect to the deleted article. Deletion discussions are carried out on separate pages dedicated to that purpose and are not deleted. Wikipedia administrators can see content that has been deleted, but other editors and visitors to the site do not.^{[note 1]} Processes exist for editors to request access to deleted content to use for other purposes.

Occasionally, deletion instances attract public attention, causing controversy or criticism of Wikipedia or other entities. Conventions and practices of deletion have caused a long-lasting controversy within the Wikipedia community, with two schools of thought forming, one generally favoring deletion as a conventional and relatively routine practice (deletionism) and the other proposing broader retention (inclusionism).

Through the AfD process, almost 500,000 articles have been deleted from the English Wikipedia between 2001 and 2021. In 2021, about 20,000 articles were nominated for deletion from the English Wikipedia. About 60% of articles nominated for deletion are deleted, about 25% are kept, and the remainder are merged with another article, redirected to another article, or met with another fate.^[3]
