He published "In Memoriam"--his poem commemorating Susy Clemens--as "SLC."

Subject: Query: Did Mark Twain publish as "Samuel Langhorne Clemens"?

I am trying to find out whether Mark Twain ever published as "Samuel Langho= rne Clemens," "Samuel L. Clemens," or "Samuel" or "Sam Clemens" AFTER the f= amous Feb. 1863 first use of "Mark Twain." Until this afternoon, when I hap= pened 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.

Many thanks
Barbara
