* "The King's English" by H.W. Fowler: This book, while not directly used in teaching Helen Keller, was likely influential in Anne Sullivan's own writing and communication skills. It focuses on grammar and style, areas that Anne Sullivan would have been focused on in teaching Helen.
* Dictionaries: Anne Sullivan would have used dictionaries to help Helen understand new words and concepts.
* Various other books and materials: Anne Sullivan used various books and materials tailored to Helen's individual needs and interests.
It's important to remember that Anne Sullivan's approach was not about rote memorization from a single book. It was about creating a personalized learning experience for Helen Keller, using various tools and methods to help her understand the world around her.
