Dr. Montessori's Own Handbook

As a result of the widespread interest that has been taken in my method of child education, certain books have been issued, which may appear to the general reader to be authoritative expositions of the Montessori system. I wish to state definitely that the present work, the English translation of which has been authorised and approved by me, is the only authentic manual of the Montessori method, and that the only other authentic or authorised works of mine in the English language are "The Montessori Method," and "Pedagogical Anthropology."
