This would be incredible. I'll tr yo track down a copy.I really like this book: Amazon.com: College of Wizardry (Advanced Dungeons & Dragons/AD&D Accessory) (9780786907175): Bruce R. Cordell: Books
It breaks down Mathghamhna in a great amount of detail. It is actually a high schoo" and university combined. I don't know if you want to go this route, but they even describe the Apprentices (level 0) daily schedule with random chore tables (and punishments). Later on you graduate to Initiate (level 1-6) and has the duties that entails and then finally you become a Guild Wizard at 7th level.
There is a lot of detailed information, all written for AD&D 2nd ed. But I feel it is very done. It is one of my favorite books that I try to use for my wizard PCs which I play or DM.
The Arcane Order is an ongoing presence in a few of our campaigns, and my Factotum character served as an ajunct professor for a semester teaching "Aberration Handling" (Students interview the Spectator Beholderkin who serves in the minor magical artifacts vault, the Otyugh that serves in the kitchens as a garbage disposal at the bottom of a shoot, dissect a Lurking Strangler and each student gets to Raise a Rust Monster). I've made up various details about the University, but I've kept it vague. Having a book with details would be an excellent resource!
