Dorothy Hermann’s highly praised biography, Helen Keller: A Life (1998), serves as an excellent companion to The Story of My Life with its detailed and impartial depictions of Keller and Sullivan. Hermann illustrates Helen's life both in private and public spheres and delves into the complex dynamic between the student and her teacher.

Keller’s autobiographical sequel to The Story of My Life is Midstream, My Later Life (1929, 1968). In this work, Keller narrates the twenty-five years following her graduation from Radcliffe College, highlighting the people she encountered and her extensive efforts in social reform.

In Helen and Teacher: The Story of Helen Keller and Anne Sullivan Macy (1997), Joseph P. Lash examines the life events of Anne Sullivan before and after her association with Helen Keller, in addition to Keller's own background. He illustrates how their remarkable lives intertwined to achieve significant accomplishments.

Margaret Marshall Saunders, a contemporary of Keller, advocated for child and animal welfare. Her most famous book, Beautiful Joe: The Autobiography of a Dog (1893), tells the story of an abused dog who eventually finds a loving home.
