These are the readable books I found that aren't obtainable anymore:
The Fall of Spiritkeep
Location: No longer exists (Stormknights library), Old unused guildhall of the Stormknights, located where Ab'dendriel is now.
Codex of the Stormknight
Scientific Contest
Location: Previously on one of Edron's beaches
Minotaur Lookout
Location: Rumor has it this scroll was completely removed from game. The previous location was on top of the mountain with the single Minotaur.
Fishing Master Certificate
Location: A certificate awarded to Santiago in Tutorial Island which is not accessible anymore. Can be found in his cellar. It was a daily respawn.

There are, for example Rookgaard scroll mentioning minotaur mage:
Still no sign of a ship yet.
Even though I am looking out since days, now.
Never again will I swear in the presence of the holy mage, in order to avoid such
duties in the future.
