Urag gro-Shub

 is an Orc mage and the librarian of The Arcanaeum at The College of Winterhold in The Elder Scrolls V: Skyrim.

He is a merchant of books and takes his job very seriously. He initiates the Hitting The Books quest when the Dragonborn approaches him, requesting research materials for the Eye of Magnus. The books Urag sells vary over time.

Interactions
After finding the books at Fellglow Keep, gro-Shub rewards the Dragonborn with five skill books: Racial Phylogeny, Daughter of the Niben, Catalogue of Weapon Enchantments, Response to Bero's Speech, The Black Arts On Trial, and 2920, Hearth Fire (v9). He also gives out a misc quest involving the acquisition of the book The Legendary Scourge found in the chest near the Dragonwall in Bleak Falls Barrow. If the player already has the book, the quest will be bugged and the questmarker endlessly pointing at the chest, even though the book is already in the players inventory. If the player still possesses the Elder Scroll, Urag buys it for 2000 Septims.

Once the player has collected enough of the misc quest books for Urag he sends word to Orc Strongholds that the player should be allowed entry.

Quests

 * Hitting the Books
 * Fetch me that Book!
 * Elder Knowledge
 * Shalidor's Insight
 * Discerning the Transmundane

Bugs
During the side quest, Return "Brothers of Darkness" book, Urag will not recognize that the player is in possession of the book. To remedy this, type in this Console Command using the tilde button (~):
 * setstage MGR20 20

This allows the player to turn in the book.

Similarly for the quest to "Retrieve Remanada", if you have already picked up the book he will not recognize that you have it nor will the quest marker recognise that the book is no longer in the whatever chest you looted it from.
 * NOTE: This also works with Find Souls, Black and White.
 * NOTE: This also works with Children of the Sky (or something like that) too.
 * NOTE: This doesn't seem to work in all cases

To return other book use command (tested with the wild elves):
 * setstage MGR20B 20
 * or setstage MGR20 20


 * When this bug occurs on PS3 or XBox 360 it is unfixable, there has been no solution found and chances are one never will.
