I am trying to find out whether Mark Twain ever published as "Samuel Langhorne Clemens," "Samuel L. Clemens," or "Samuel" or "Sam Clemens" AFTER the famous Feb. 1863 first use of "Mark Twain." Until this afternoon, when I happened to check on it, I thought he published "In Defense of Harriet Shelley" (in North American Review, 1894) under "Samuel Langhorne Clemens," but he did not--he published that essay under "Mark Twain." If anyone knows whether there is a source for this information, please let me know. I've checked Rasmussen, and a few other sources.
