William Dean Howells 
My Mark Twain (Barnes & Noble Digital Library) 
Reminiscences and Criticisms

Published in 1910, this book is a testament to the long friendship between Howells and Twain.  ‘Emerson, Longfellow, Lowell, Holmes—I knew them all and all the rest of our sages, poets, seers, critics, humorists, ‘ Howells writes;  ‘they were like one another and like other literary men; but Clemens [Twain] was sole, incomparable, the Lincoln of our literature.’ The second half of the book collects Howells’s perceptive reviews of Twain’s works.
