|"Is this all real? Or has this been happening inside my head?"
The subject of this article is of a real-life person, place, group, company, product, or creative work that has been mentioned "in-universe" in a canon source. The Harry Potter Wiki is written from the perspective that all information presented in canon is true (e.g., Hogwarts really exists), and, as such, details contained in this article may differ from real world facts.

Behind the scenes
- In the film adaptation of Harry Potter and the Philosopher's Stone, the shrieking book, in which Isaac is mentioned, appears to be a copy of The Works of the Most Reverend Dr. John Tillotson.
