Which fictional textbook did J.K. Rowling publish to support Comic Relief in 2001?

J.K. Rowling published Fantastic Beasts and Where to Find Them to support Comic Relief in 2001.

The book is presented as a Hogwarts textbook written by the fictional magizoologist Newt Scamander. Its format includes Harry Potter’s, Ron Weasley’s, and Hermione Granger’s notes, making it resemble a borrowed schoolbook rather than a conventional narrative.

Alongside Quidditch Through the Ages, it was one of two charity books published in 2001 to raise money for Comic Relief. Rowling later developed the title into a film series, but the original book is a short companion work about magical creatures. Newt Scamander became the central character of the later films.
