Help:Permalinks

A permalink is a "permanent link"; a type of URL designed to refer to a specific information item and to remain unchanged permanently, or at least for a lengthy period of time. This allows you to cite an article or send a link to another person which you can be sure displays the specific version you were viewing at the time -- any later revisions will not be visible. This is helpful if you are concerned that the information you are referring to might be deleted, altered, or vandalized between the time that you send the link and someone else views it.

How do I create a permalink?
When you click "permalink" or "permanent link" in the navigation bar, you are taken to a revision page which displays the following information just below the page title:
 * Revision as of [time, date] by [username] (Talk | contribs | block)
 * (diff) ←Older revision | Current revision (diff) | Newer revision→ (diff)

You can also find the revision page for any old version of an article by clicking on the appropriate revision date in any page history.

The url from this page will look something like this:
 * http://wikiname.wikia.com/index.php?title=Namespace:Pagetitle&oldid=2828

Copy this URL from your browser's address bar to link to this particular revision of a page. The "oldid" at the end ensures that the page will look exactly as it did when you created the link.

How do I use a permalink on a wiki page?
Permalinks must be added using the normal external link format, with a space between the URL and any desired description text:
 * Revision as of August 1

If you create such links frequently, you may wish to copy the Permalink Template to your wiki and alter it as desired (see Help:Templates for more information).

You can also view the revision ID ("oldid") of the current version of a page using the new variable.

Older versions of MediaWiki
Prior to MediaWiki 1.5, only old revisions could be linked to, and these were not permanent, since deletion and undeletion of a page would change the revision ID, and moving a page would change the revision ID. The "oldid" used in 1.5 will remain a permanent link unless a page is actually deleted.
