This is the extensively revised second edition of Kelly's A cyclopaedia of American medical biography, comprising the lives of eminent deceased physicians and surgeons from 1610 to 1910. (Philadelphia: W.B. Saunders, 1912). The extensively revised third edition published in New York by D. Appleton in 1928 also had a very different title: Dictionary of American medical biography. Lives of eminent physicians of the United States and Canada, from the earliest time. Although the title page of this second edition does not indicate it, this work was written by various physicians, including Kelly and Burrage, who also served as editors. It begins with a comprehensive bibliography of biographical literature on which the authors based many of the biographies. Digital facsimile of the 1920 edition from Google Books at this link.
