Many thanks to David Seaman, coordinator of the University of Virginia's Electronic Text Center, for his many hours of work on this project. Also contributing hard work to this hypertext: The staff of the university's Special Collections department, particularly Heather Moore, who gave extensive assistance with the research, and Ned Berkeley, who scanned in the first edition covers, the obscene illustration from the sales prospectus, the prospectus advertising, and the 1884 Twain photo. Polly Page in Printing Services provided the microfilm from which the first-edition illustrations were scanned.
