If you want to do city tasks for the Academy of Arcane Science you will need to first do this short delivery quest. City tasks are only for players who are in guilds and reward you with status points.
Neophyte Jhanov (in Academy of Arcane Science library) asks you to find Archivist Jindlefog in the Academy of Arcane Science in North Freeport. To get to him you need to go down the elevator and you will find him down there at +10, -38, -119. The elevator doesn't really look like an elevator, and you push a small floating lever to go down.
This opens up the Report to Paragon Jalex quest (see related quests) which then allows you to do City Tasks for the Academy of Arcane Science.
