For step 3 below, the disruptive students spawn throughout the library (upstairs and downstairs). Since it is a timed event, you are advised to clear all the trash in the library before carrying out step 2 (which starts the timed event).
Steps[]
Speak to Marian Cross on 2nd Floor at ( -75, 49, 78 ) Copy/waypoint -75, 49, 78 in the frozen library.
Speak to J.G. Hill on the upper level of the library at ( 74, 71, -116 ) Copy/waypoint 74, 71, -116. Tell her that the authors initials are "C.O.".
Defeat 7 disruptive students. This is a timed event with a limit of 10 minutes. If you run out of time, you will have to repeat step 2 again to restart the event.
Recover the other five Sealed Scrolls. The first two are in the same zone, the other three require entering the Tower of Frozen Shadow: Umbral Halls instance.
Shadowed Corridors: The Sealed Aged Scroll can be obtained on the first floor. On entering the south-east room, a shadowbeast spawns. Kill that and a small chest drops containing the scroll.
If the mob isn't there, run through the rooms on this floor spawning the normal guys (one spawns at a time in each room, you have to exit and reenter each time). Eventually a Large Undead Gnoll will spawn and drop the scroll.
Note for EQMaps users: it says "Ancient Gnoll" but "Large Undead Gnoll" dropped it
Umbral Halls: The Sealed Dusty Scroll can be obtained on the fourth floor as follows.
Click on the canopic jar at ( -69, 294, -8 ) Copy/waypoint -69, 294, -8, killed the three undead that spawn, and obtain the stomach of Amontehepna.
Click on the canopic jar at ( 37, 290, -42 ) Copy/waypoint 37, 290, -42, killed the three undead that spawn, and obtain the liver of Amontehepna.
