Of course, the Mages Guild is no mere curiousity shop. Persons judged worthy to join the Mages Guild are given access to libraries and laboratories of every description. Not all at once, of course, but gradually. One has to be careful about whom one trusts with great power. After all, the Mages Guild is all about responsibility. If you're thinking of making wizardry your profession, you should join and work your way up the ranks.
