Compile data about books referenced on Swedish wikipedia.
First extract all uses of Template:Bokref https://sv.wikipedia.org/wiki/Template:Bokref
Then try to identify unique books used. Obviously the same book can be refered to with different template usages, so we need to identify them via ISBN and Libris no.
Look at T205384 which probably includes large chunks of code/workflow to do this. https://figshare.com/articles/Wikipedia_Scholarly_Article_Citations/1299540 was used previously to grab ISBN sources, but it's old :)
