Shalidor's Insights (Quest)

Background
"Urag gro-Shub is looking for writings by the Arch-Mage Shalidor, so that he can translate them into something useful for the College. He's asked that I attempt to find another copy for him."

Walkthrough
Once you have been admitted to the College of Winterhold you have access to the Arcanaeum. The Arcanaeum is tended by an old Orc named Urag gro-Shub. You have to ask Urag if he needs any special books to be found. Urag will talk about the Arch-Mage Shalidor and his understanding of magic. Urag will then ask you if you wish to find Shalidor's Insights for him. Accept.

In the chest located on the map is a copy of Shalidor's Insights. Return the book to Urag and receive 30 gold. Urag says he'll need a couple of days to translate the book. Wait 48 hours and ask Urag how the research is coming along, and—if you've waited long enough—he'll say they've completed the translation, and gives you three Shalidor's Insights: These are scrolls which lower the cost and increase the duration of spells for 120 seconds. The kind of scroll you get depends on which tree (Destruction, Alteration, Conjuration, ...) you have the highest level on. Uncommonly, the Dragonborn will get a random magic skill increase (Destruction, Alteration, Conjuration, ...). This increase does NOT count as one of the five training points each level but it functions in the exact same manner as it would a trainer.
