Speak to Gradav at the Guardian's Library in Karazhan.
Quest Text
Was I supposed to be looking for this journal? It can't be... I don't quite recall...
Of course! It is Gradav you're thinking of. He was looking for the book when I got here. Surely he must've found it by now; why don't you go ask him about it?
I'd lend you a hand... but these books are just so... interesting!
Completion
Can't you see I'm in the middle of something here? What do you want?

The Guardian's Library is the large hall after Curator. The mobs here will auto-clear some time after the Shade of Aran has been defeated.
