I recently responded to a query about MT's erotic writings. I did not have a citation at hand and gave some incorrect information. Here is the cite for the item I mentioned: Author: Twain, Mark, 1835-1910. Uniform title: Mammoth cod. Title: The mammoth cod, and Address to the Stomach Club / Mark Twain [i.e. S. L. Clemens] ; with an introd. by G. Legman. 1st ed. Milwaukee : Maledicta, 1976. Description: 25 p. ; 23 cm. Series: Maledicta Press publications ; 1. Other entries: Legman, G. (Gershon), 1917- Twain, Mark, 1835-1910. Some thoughts on the science of onanism. 1976. Cheers, Rhio H. Barnhart UC Davis
