{{main|Help:Interlanguage links}}
'''Interlanguage links''' are links from any page (most notably articles) in one language edition of Wikipedia (or another Wikimedia project with different language editions) to one or more nearly equivalent or exactly equivalent pages in another language edition of ''the same'' Wikimedia project. As of February 2013, the use of "local" links for interlanguage linking has been deprecated, with interlanguage link data being centralized on [[Wikipedia:Wikidata|Wikidata]], a [[data model|structured]] [[knowledge base]] project. Pages with their interlanguage links on Wikidata display an "Edit links" button under the language list.

{{A note}} The information below is '''deprecated''', and kept for historical purposes.

Prior to February 2013, interwiki links were generated using "local" links within articles, taking the form <code><nowiki>[[language code:Title]]</nowiki></code>, where the language code is the two-letter code as per [[ISO 639-1]]. (See [[m:List of Wikipedias|Complete list of language Wikipedias available]]: English language is "en", German is "de", etc.) So, for example, in the English language article on [[plankton]], which is available on many other wikis, the interlanguage links might look like this:

<pre><nowiki>
[[ar:عوالق]]
[[de:Plankton]]
[[eo:Planktono]]
[[es:Plancton]]
[[fr:Plancton]]
[[nl:Plankton]]
[[ja:プランクトン]]
[[ko:플랑크톤]]
[[pl:Plankton]]
[[pt:Plâncton]]
[[ru:Планктон]]
[[simple:Plankton]]
[[zh:浮游生物界]]</nowiki></pre>

These links do not show up in the article, but instead populate the "Languages" list on the sidebar. While they can be theoretically located anywhere in the article, they were typically placed at the bottom.
