To gain access to the next floor of the library click on the bookcase wall by Custodian Naddar ( -65, 37, -71 ) Copy/waypoint -65.48, 37.00, -71.02. It will lift into the ceiling and give you access to a hidden passageway that leads up to another teleporter with a reddish color. This is a trap! When you step on it three rounds of mobs will charge one after the other. Zulfiqar the Indomitable will be leading the last group. Now the teleporter will have the normal color and it will take you to the Grand Hall.
Clear out the mobs in the Grand Hall and then touch each of the three big symbols on the walls. This will cause a magical book staircase to form in the center of the room. This takes you up to the last floor where you will find Head Archivist Farooq.
Hail Farooq to tell him the location, the weapon and the murderer. You must answer the questions correctly to update the quest; otherwise you will have to redo the entire zone from the start. Have one individual who has kept track of the answers undertake the dialogue.
The Scholar will spawn as a named ^^^ and attack you. Kill him.
Return to Cataloger Jamillah at the entrance of the library to complete the quest.
