Those were tomes removed from the game previously and turned into items you can only get for a small while. Afterwords when the NPC is gone you can trade them to is gone they become useless so you might as well throw them away. So not really needed.
Bi Stones = will be around for good (As we know it)
Irregular Tomes = only around during special events, and then become useless when event NPC is gone. (If you save them for another time the event is up, you can only trade them for crappy fireworks type items, so useless)
