Философский камень
The book's title was changed due to the American publisher's concern that children would be confused by a reference to philosophy. Other translations have also changed the first book's title, for instance, the French translation which changed "Harry Potter and the Philosopher's Stone" to "Harry Potter at the School of Wizards" for the same reason as the American translation, citing that the reference to the Philosopher's stone legend was "too obscure for a book aimed at the youth."
