The J. Whitridge Williams Collection contains correspondence (1920-1936), newspaper clippings, and biographical material. The collection is primarily composed of the first five editions of Williams' Obstetrics: a Textbook, A Book for the Use of Students and Practitioners. These editions were Williams' personal copies and contain his extensive annotations and corrections. A copy of his A Sketch of the History of Obstetrics in the United States up to 1860 is also included.
