Figures in brackets after the volume titles indicate 2017’s rankings if applicable. RE indicates a volume that came out before 2017 but did not appear in last year’s rankings. If a volume came out in 2017 but did not rank, then this is indicated. If a volume is new then no figure is given.
The list below is the POS (bunsho) ranking for the full year 2018. The rankings cover the top 500 sellers of all books during the year, but those given below are just the light novels on the list. This is why there are many gaps in the rankings. There are no sales figures given for this data, and the data set is different from the one Oricon uses, which explains differences in the rankings. It has the advantage, though, of reporting much lower ranks than Oricon does.
Please note that unlike previous years this data was taken directly from the top 500 myself. There may be things that are missing as a result (eg. I didn’t spot Ameku Takao no Jiken Karte when going through as the rankings give the volume title only for that one). If you notice anything missing please let me know
Bear in mind that, unlike Oricon, POS rankings use the calendar year for the yearly rankings data.
