Which J.K. Rowling book introduced the wizarding school Hogwarts to readers?

Harry Potter and the Philosopher’s Stone introduced the wizarding school Hogwarts to readers.

In the novel, Harry learns on his eleventh birthday that he is a wizard and receives an invitation to attend Hogwarts School of Witchcraft and Wizardry. The school becomes the central setting for most of the main series and is divided into four houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin.

The first book establishes many details that later stories expand, including the Sorting Hat, magical subjects, Quidditch, and the school’s staff. Hogwarts is fictional, but Rowling drew on memories of schools and on British boarding-school traditions when shaping the setting.

The title differs across English-language editions. In the United States, the same novel is called Harry Potter and the Sorcerer’s Stone. Both titles refer to the same first book and the same magical object.
