There's nothing of the sort in-game yet, but as more people latch on to the lore, SE gets more excited about adding things like bestiaries, expanded journals, and gear compendiums where we'd unlock "tome" / "library" entries for completing certain sets of gear or killing certain sets of mobs, or completing certain quest lines.

Can't help you there - I remember all this stuff because I build personal libraries for use in wikibuilding, lol.
