You can also look this up directly on wikidata:
<https://www.wikidata.org/w/api.php?action=wbgetentities&sites=enwiki&titles=Douglas_Adams&props=>

A bit more terse, and with full URLs in the output:
<https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q42&props=sitelinks|sitelinks/urls&sitefilter=enwiki>

You can also let yourself be redirected directly:
<https://www.wikidata.org/wiki/Special:GoToLinkedPage/enwiki/Q42>

Or the the reverse redirect:
<https://www.wikidata.org/wiki/Special:ItemByTitle/enwiki/Douglas_Adams>
