Motivation[edit]

All printed material published in the 18th century in Germany and other German speaking areas is cataloged in VD 18 (Q1739957), often with digitized editions. Corresponding Wikidata items should be linked to this bibliography by the VD18 number. For examples of works already in Wikimedia projects see Category 18th century in German Wikisource, or this (fairly incomplete) query:

SELECT ?p ?pLabel ?year WHERE {
  ?p wdt:P31/wdt:P279* wd:Q571 .
  ?p wdt:P577 ?date .  
  ?p wdt:P407 wd:Q188 .
  FILTER (year(?date) >= 1701) .
  FILTER (year(?date) <= 1800) .
  BIND (year(?date) AS ?year) .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "de". }
}

Try it!

Disclaimer: my employer hosts the VD18 database and will extend a web portal for the bibliography that could benefit from linking with Wikidata. -- JakobVoss (talk) 20:11, 8 November 2018 (UTC)[reply]
