[edit]

Filtering all publications results in a timeout but selected publication types from the 18th century can be queried like this:

SELECT ?p ?pLabel ?pDescription ?year ?vd18 WHERE {
  # books and periodicals (all publications would lead to timeout)
  { { ?p wdt:P31/wdt:P279* wd:Q571 } UNION
    { ?p wdt:P31/wdt:P279* wd:Q1002697 } }
  
  # filter by date
  ?p wdt:P577 ?date .  
  FILTER (year(?date) >= 1701) .
  FILTER (year(?date) <= 1800) .

  # Publications with German or unknown language
  OPTIONAL { 
    ?p wdt:P407 ?lang 
    FILTER NOT EXISTS { ?p wdt:P407 wd:Q188 }
  } 
  FILTER (!BOUND(?lang)) .
  
  # get VD 18 ID, year, and labels
  OPTIONAL { ?p wdt:P6135 ?vd18 }
  BIND (year(?date) AS ?year) .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "de". }
} ORDER BY DESC(?vd18)
