Wikipedia:Undeletion policy
Undeletion
See the Wikipedia:Deletion log for pages that have been recently deleted. See Wikipedia:Votes for undeletion if you are concerned that a page may have been wrongly deleted.
To request that a page (or image) be restored,
- Place the page title on Wikipedia:Votes for undeletion, with the reason why you think it should be deleted
- It will remain there for a period of ten days, giving other users the chance to agree with the undeletion nomination or to object.
- A user's opinion will be counted if that user:
- has been in existence at least one week before the listing, and
- has at least 25 non-minor article edits logged
- Regardless of the above requirements, the page's initial author may vote (once).
- If at any time prior to ten days elapsing, at least 3 people (including the person who proposed it) currently want to undelete and a majority are currently in favor of undeletion, the page may be undeleted by a sysop. If ten days elapse and the proposed undeletion lacks 3 supporters and a majority, then the page remains deleted (to avoid rapid redeletion since deletion requires a 2/3 majority). When a sysop undeletes an article, they should list the article on Wikipedia:Votes for deletion. Further discussion can take place on the votes for deletion page, and after about a week the undeleted page will either be deleted again, or left undeleted.
If the page was obviously deleted 'out of process' (ie- not in accordance with current deletion policy), then a sysop may choose to undelete immediately. In this case, the sysop who deleted the page should be informed of the undeletion and the reason for it. The page should also be listed on VfD. If you are unclear as to whether it was out of process or not, the normal undeletion procedure should apply.
