What is the title of J.K. Rowling’s 2008 companion book about wizarding creatures?

J.K. Rowling’s 2008 companion book about wizarding creatures is Fantastic Beasts and Where to Find Them.

The book is presented as a Hogwarts textbook written by Newt Scamander, a fictional magizoologist. Rowling published it under the author name Newt Scamander, with proceeds from the original charity edition supporting Comic Relief and Lumos-related work.

Its entries describe creatures such as the Acromantula, Basilisk, Banshee, and Niffler. The Hogwarts textbook framing makes the book look like an object from the wider wizarding world, and Harry and Ron’s imagined annotations add to that effect in the original presentation.

The title later became the basis for a film series beginning with Fantastic Beasts and Where to Find Them in 2016. The film story expands Newt Scamander from a fictional textbook author into a central character.
