{{ Self-reference link}} is used in articles about Wikipedia to link to a Wikipedia page in the form of an external link, so that the link will still work on mirrors and forks of Wikipedia. "Srlink" is short for "self-reference link". For when a self-reference link may, or should not, be used, see Wikipedia:Manual of Style/Self-references to avoid.
