Which Hogwarts textbook did J.K. Rowling publish as a 2001 charity companion book?

J.K. Rowling published Fantastic Beasts and Where to Find Them as a 2001 charity companion book.

The book is presented as a Hogwarts textbook by Newt Scamander, a fictional magizoologist. Rowling wrote it as a companion to the Harry Potter series, including annotations attributed to Harry, Ron, and Hermione in the original charity edition.

Proceeds from the first edition supported Comic Relief. The book describes magical creatures and includes Scamander’s notes about species, habitats, and encounters. Its fictional textbook format gives readers an expanded view of the wizarding world beyond the main novels.

The title was later used for the 2016 film, but the film is not a straightforward adaptation of the short book. Instead, Rowling wrote a new screenplay featuring Newt as its central character and set the story decades before Harry’s time.
