This seems very interesting: maybe, there will be a time when Wikidata (or similar) will host the bibliographic records

of thousands of libraries...

Right now, I'm not sure if we want to discuss a massive upload of these records in WD,

because:

* they are in MARC, which is way more complex than the list of bibliographic properties currently in WD

* they will be in German

* do we really need so many records of books, articles and work, at this early stage?
