Canon Library

The Canon Library is a library in Headquarters that Agents can borrow the books, movies, or generally anything regarding a specific canon if they do not have the material themselves for an exorcism or if they need to familiarize themselves with a new canon.

It is unknown exactly who (or what) staffs the Canon Library, since Agents are not allowed to enter and are required to ask for what they want at the door. The Librarian is perfectly happy with this state of affairs.
