I regularly keep uptaded of the few advancements of Wikidata:WikiProject Books (since most decisions are done already) and wish to contribute more in the future.
Currently, I'm getting more and more interested by the Wikibase docker image possibilities.
I believe manually editing should be encouraged by the community, as it takes time (100 years?) to build a knowledge graph model, we would better do it slowly and carefully.
