This category tracks pages using ISBN [[Help:Magic links|magic links]]. Magic links will be removed from the MediaWiki code at some point. As of November 2016, there is no need to make changes to these pages. A consensus decision will determine how these identifiers should be modified. (For further information see [[:mw:Requests for comment/Future of magic links]], for current alternative ways of creating these links see [[:mw:Help:Magic links]].)
