Corrected entry: If it's so easy for Stephen Strange, a mere student, to conjure up a gateway inside the library whilst it is forbidden and without being noticed by the guardian present, surely a former master like Kaecilius could easily do it as well and steal the entire book of Calgiostro instead of only a few pages, without anyone noticing.

Correction: Kaecilus entered the library with a large group of followers and decapitated the guy watching them. He wanted to be seen. Secondly Kaecilus actually had the book in his hands, so if he wanted the book he would have taken it, instead of the pages he took.
