SOE said they fixed the sorting, who'd have figured they'd not have gotten that fixed on the first try...
The books are selling through DoF, you have to take a couple of carpet rides, or see if anyone on your server are selling the essentials 50-59 for provisioners at the broker. Cost at merch is around 5G 85S, I put a few up for 6 - 7G on Najena and they sell ok.
Safe travels friend.
