Approximate equivalent of the DNB No WP on WikisourceEdit

This query returns Wikisource pages where at least one of the main subjects is missing an English Wikipedia article. Right now this excludes DNB redirect pages; many of these are missing main subjects entirely.

SELECT ?subject ?subjectLabel ?ws WHERE 
  ?item wdt:P1433 wd:Q15987216.
  ?item wdt:P31 wd:Q19389637.

Get data about people based on items connected through Commons sitelinksEdit

I don't expect to reuse this query much, or maybe ever, but the pattern for "get the person, either directly or through their category" is useful on Commons generally. Also, while I didn't think of this earlier, it wouldn't be that hard to directly input sitelinks.

SELECT ?subject ?birth ?death ?commonscat ?creatorpage

  SELECT ?subject WHERE {  
    VALUES ?item {wd:Q332331 wd:Q449885 wd:Q6264333}
      ?item wdt:P31 wd:Q5.
      BIND (?item AS ?subject).
    } UNION {
      ?item wdt:P301 ?subject.
} AS %subjects
  INCLUDE %subjects.
  OPTIONAL {?subject wdt:P569 ?birth.}
  OPTIONAL {?subject wdt:P570 ?death.}
  OPTIONAL {?subject wdt:P373 ?commonscat.}
