In the databooks, there's something called Konohagakure 100 Leaves Collection. Each "leaf" gives small bits of information about different things. However, there've only been 78 leaves so far (including the ones in the new databook) and they only appear in the databooks. Seeing how there are 22 leaves yet to discover and two of the Kujiin unused, it's possible that we get yet another databook sooner or later.
