This two-volume extra-illustrated version of The Life and Work of Susan B. Anthony contains 38 tipped-in letters and autographs inserted into the book by its author, Ida Husted Harper. She placed them into the book at the appropriate point in the narrative. The material covers the bulk of Anthony's working life. 19 of the letters are addressed to Anthony, and another 3 to Elizabeth Cady Stanton. The letters were evidently in the possession of Harper, who had access to Anthony's correspondence while writing the biography.
