New Library Book Return Quest Unlocked at Level 30 in WoW: Forever

At Level 30, players can hand in 25 Library Books for new rewards - even though only one of them might be usable in the Forever beta.

On the WoW: Forever Beta, players who have reached level 30 can now turn in 25 Library books to claim an even bigger reward. Unfortunately, though, only one of them can be equipped at level 30.

Library books are found all around Azeroth, and upon handing them in, you can claim different rewards at different levels. The quest for 25 books requires level 30.
