Awesome work Ayantir! Thanks for always doing these threads. It's great to have a plan. (You should also join us on Gitter, merlight too)
I am not sure if "AvA Keep Dumps" is that useful as the ids seem to be different between servers.
As for Librarian Book Manager, I still have my half finished addon with a list of *where* books have been found. Maybe I'll combine them and integrate them into Lorebooks...
P.S:
