Dear Sally, This will seem like ancient history, probably, but Professor Daniel M. McKeithan of the University of Texas at Austin published a book in 1958 titled COURT-TRIALS IN MARK TWAIN AND OTHER ESSAYS (The Hague: Martinus Nijhoff). He tried to cover the most significant examples of Twain's interest in the administration of justice. Herbert Feinstein wrote an article on Twain copyright battles--"Mark Twain & the Pirates," HARVARD LAW SCHOOL BULLETIN 13 (April 1962): 6-18. These are a start, anyway. Sincerely, Alan Gribben Auburn University Montgomery
