Wright, Wayne W. (2000). Thornton W. Burgess: A descriptive book bibliography, revised and enlarged edition. Sandwich, MA: The Thornton W. Burgess Society. [This is an invaluable guide to Burgess's vast and sometimes confusing literary output, including foreign and translated editions. Wright also indicates which newspaper stories comprise which book, an enormous help!]
Dowhan, Michael W. (1990). Thornton W. Burgess, Harrison Cady: A book, newspaper, and magazine bibliography. New York: Carlton Press.[An astounding guide, particularly useful for tracking down TWB's non-bedtime story work. One copy available in the Minuteman Library network--a non-circulating reference book in the Westwood Library's children's room (be prepared to sit at a tiny table).]
