[2020] The Spire Library

This sounds like you are getting confused between Orbs and Crystals as the Spire of Eternity only has a maximum of 12 Crystals each week. These represent the unlocking points for the rewards that the Fellowship can win.
The 330 you are referring to are the Orbs that the Fellows get for completing each encouter, these are what unlock the Crystals, that then grant the Ranking Points.  

Not about winning @ButterCup about hoping that we are able to help players if they are stuck with any terminology in the game.
As with all Ancient Wonders their benefits increase as they are upgraded, this specific one can grant between 0.5 and 15 Ranking Points per Spire Crystal.
