I'm a fairly latecomer to the beta, so my vagueness about Sorcery really isn't because senescent. That's just the way I normally act. 
Yes, I know it's a Magic technology. I know it gives you elemental books you can (without another tech) sell to other leaders.
But why does research suddenly give you a bunch of a magical books at one time?
If I didn't research the books or buy them from anyone else, would any of my magically inclined champions be able to cast in the spells in them upon reaching the right magical level (ie, apprentice, adept, etc) that seems to auto-pop spell availability?
Where are the contents of the books listed? They aren't in the help system. It looks like a placeholder sentence.
