Which J.K. Rowling book introduced the wizard Newt Scamander as its credited author?

Fantastic Beasts and Where to Find Them introduced the wizard Newt Scamander as its credited author.

The book is presented as a Hogwarts textbook written by Newt Scamander, a fictional magizoologist. Harry Potter, Ron Weasley, and Hermione Granger are listed as former owners of the copy associated with the school story.

Rowling originally published the book in 2001 as a charity companion volume to the Harry Potter novels. Its entries describe magical creatures and include humorous notes attributed to the students who share the textbook.

The title later became the basis for a film series set decades before Harry Potter’s school years. In those films, Newt is a central character played by Eddie Redmayne, but the original book is a short reference-style work rather than a conventional novel.
