Does anyone know what JK Rowlings pseudonym book is called?

Question

Ive heard that JK Rowling has other books out besides the Harry Potter series, and I heard that its under a different name. Does anyone know what the/these books are called, and under what name?

Answer 1

You could be thinking of Quidditch Through the Ages (by "Kennilworthy Whisp") and Fantastic Beasts and Where To Find Them (by "Next Scamander").

They're technically not written under a pseudonym (J.K. Rowling's name is inside), but her name is not on the outside.
