After long discussions, me and Chiara Storti reviewed the "Pride and
Prejudice" item and some of it's related items.
We then wrote this *long* message here:
It's the first attempt to find a solution for Wikidata and books,
especially regarding Wikisource.
It's not complete but it's a start.
I encourage you to take your time to read it.
As Sam Wilson is working on Ws-search, we could start populating some items
with the right statements.
