An item [[ https://www.wikidata.org/w/index.php?title=Q61988325&oldid=876136391 | was created ]] with a link to sourceswiki (or "old Wikisource", mul.wikisource...). However, the link is not displayed anywhere on the page. (Subsequently, the item was merged to [[ https://www.wikidata.org/wiki/Q5612101 | another ]] but this page doesn't display the link either.)
By the way, should this happen at all? I must have missed that sitelinks to sourceswiki are allowed.
Live list of them: [[ https://query.wikidata.org/#SELECT%20%3Fitem%20%3Ftitle%20%3Farticle%20WHERE%20%7B%0A%20%20%3Farticle%20schema%3Aabout%20%3Fitem%3B%20schema%3AisPartOf%20%3Chttps%3A%2F%2Fwikisource.org%2F%3E%3B%20schema%3Aname%20%3Ftitle%20.%0A%7D%20ORDER%20BY%20%3Ftitle | query ]].
