I don't remember which one of my friends wished for one central independant database.
I just realised, after editing a couple of messed up books on LeafMarks, that I have been using something very similar for quite some time now. Maybe because I like going for at least two different sources (the more the merrier, really), it didn't click in my head right away. This database is not complete, but it is still pretty darn good.
Here you have it:
