Locate and speak to Urag gro-Shub . If there's any business he wants to attend to, then you're good to go. Just like the previous Quest, he wants a [ random ] book from a [ random ] location. There's a marker where the book is. It can be in a cave, in a fort, but it's inside a chest. Once you got the book, bring it back to Urag to receive your payment...
Note: As it happened, this quest can ALSO be glitchy. For example, you can FIND a book BEFORE DOING this quest , and then once you have the quest Urag will tell you to go find a book from a dungeon you've already visited (for me it was "Glories and Laments").
Urag will NOT take the book from you're inventory and the book will NOT be in the chest where the game points to. Oh, and you CAN'T drop the book out of your inventory. Lesson learned: SAVE before hand.
