Candidates

• Apart from those of the query from the proposal, here is a query for more candidates, for some of them their respective fitting editions (version, edition or translation (Q3331189)) should get a Incunabula Short Title Catalogue ID (P6494) statement:

  SELECT DISTINCT ?item ?itemLabel ?pub ?inception ?istc WHERE {
    {
      ?item (wdt:P31/wdt:P279*) wd:Q3331189.
      ?item wdt:P577 ?pub.
      FILTER((?pub > (xsd:dateTime("1449-01-01T00:00:00Z"))) && (?pub < (xsd:dateTime("1501-01-01T00:00:00Z"))))
    }
    UNION
    { ?item (wdt:P31/wdt:P279*) wd:Q216665. }
    SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en,de,fr,la". }
    MINUS { ?item wdt:P195 wd:Q82133. }
    OPTIONAL { ?item wdt:P577 ?pub. }
    OPTIONAL { ?item wdt:P571 ?inception. }
    OPTIONAL { ?item wdt:P6494 ?istc. }
  }
  ORDER BY ?istc ?pub ?inception
  LIMIT 100

• And here the query used to bring the catalog code (P528) to this property via QuickStatements:

  SELECT
  # ?item ?itemLabel
  ?qid ?P6494 WHERE {
    ?item p:P528 ?st.
    ?st ps:P528 ?value.
    ?st pq:P972 wd:Q634670. # Incunabula Short Title Catalogue
    BIND(SUBSTR(STR(?item), 32) AS ?qid)
    BIND(CONCAT('"', ?value, '"') AS ?P6494)
    SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  }
  LIMIT 100
  

  Try it! ; Try it!
• The values in catalog code (P528) don't have any special references, only reference URL (P854) with unspecific redirects, cf. here:

  SELECT ?prop ?propLabel ?count WHERE {
    {
      SELECT ?refProp
             (COUNT(?refProp) AS ?count)
             WHERE {
        ?item p:P528 ?statement.
        ?statement pq:P972 wd:Q634670.
        ?statement prov:wasDerivedFrom ?wdRef.
        ?wdRef ?refProp [].
      }
      GROUP BY ?refProp
    }
    ?prop wikibase:reference ?refProp.
    SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  }
  ORDER BY DESC(?count)
  

  Try it! ; Try it!. And I've removed them using this query:

  # query that can be used to remove redundant values of P528 that are now in P6494:
  # download as CSV, put a minus sign in front of the second column and then run in QuickStatements
  
  SELECT
  #?item ?itemLabel ?value
  ?qid ?P528
  #?istc
  WHERE {
    ?item p:P528 ?st.
    ?st ps:P528 ?value.
    ?st pq:P972 wd:Q634670. # Incunabula Short Title Catalogue
  #  OPTIONAL { ?item wdt:P6494 ?istc. }
    BIND(SUBSTR(STR(?item), 32) AS ?qid)
    BIND(CONCAT('"', ?value, '"') AS ?P528)
    SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  }
  LIMIT 100
