I hope I'm not beating this to death, but I love a good challenge. Using Proquest's American journal archive, I generated a list of 140 articles that were published with Twain as author with a cutoff date of around 1912. I ran that through RefWorks to generate an HTML bibliography which can be seen at: http://faculty.quinnipiac.edu/libraries/tballard/twainjournals.html I hope this is helpful.
