These rankings are series rankings, not volume rankings. The overall rankings list (the top one) has gaps as things that are not light novels (mostly manga) have been left out. This treatment has not been applied to the literature rankings, so there are a couple of non-light novels on there.
These rankings cover bookwalker ONLY but this is a major source of light novel sales, so is worth including despite being limited to a single site.
Obviously this is the Japanese bookwalker, not the global one.
Unlike in previous years, there is no “male” or “female” rankings this year.
