Busby, Mark, and Dick Heaberlin, eds., From Texas to the World and Back: Essays on the Journeys of Katherine Anne Porter, Texas Christian University Press, 2001.

Busby and Heaberlin have collected several essays written by scholars and critics, following the development of Porter as a writer.

Carlson, Elof Axel, The Unfit: The History of a Bad Idea, Cold Spring Harbor Laboratory Press, 2001.

Carlson has put together a study of the philosophy and history of eugenics, the philosophy that led to the involuntary sterilization of people in the United States who were deemed unfit and later to the Nazi campaign of creating a super race. This is not a pleasant book to read but one that gives the reader some idea about why Mrs. Whipple was so concerned about hiding her son's supposed lack of normal mentality.
