有声读物: Mark Twain; his life and work. A biographical sketch

As far as anyone has been able to establish, Will Clemens was NOT related to Sam Clemens (Mark Twain), though they did become acquaintances. The 200-page biography Will Clemens wrote and published himself may have been the earliest full-length study of MT. It was published July 1,1892 as "No. 1" in a paperback series called "The Pacific Library," price 25¢, and did well enough to be republished in 1894 by a publisher in Chicago. Throughout the book Clemens relies mainly on other writers' previously published work. (summary by John Greenman)
