Which 2001 J.K. Rowling book was written as a Hogwarts textbook credited to Newt Scamander?

Fantastic Beasts and Where to Find Them is the 2001 J.K. Rowling book presented as a Hogwarts textbook by Newt Scamander.

The book is a fictional textbook about magical creatures in the Harry Potter world. Its credited author, Newt Scamander, later became the central character in the Fantastic Beasts film series. Rowling wrote the published companion book to resemble a student’s Hogwarts reading material, including fictional notes associated with Harry and Ron.

Quidditch Through the Ages is another Hogwarts-associated companion book, but it covers the history and rules of the wizarding sport. The two books were published together in support of Comic Relief. The later films are not straightforward screen adaptations of the 2001 textbook; they expand the character and setting into an original prequel-era story.
