I noticed nobody responded to that question. I believe it has come up before, so check the archives. I seem to recall at one point there was an article that listed the top 100 works about Mark Twain--it included reference, biography, special topics, primary works, and so on. Does any LIST-member recall where that article appeared? Maybe we could link it to the FORUM site and/or the proposed FAQ. Harold K. Bush, Ph.D Saint Louis University
