Mark Twain is one of my favorite authors. The Mark Twain House is only an hour from where I grew up. I've listened to many of his short stories on audio and fell in love with his accounts of being a newspaper reporter in the mid-west. I own a 26 volume collection of his major novels and most of his favorite short stories - every copy bears his litho signature. A litho signature may not mean much, but Twain rarely allowed this, and as far as I know, never without his personal approval. I wouldn't dare take the books out. They have been passed down through my family and are, for their age, in quite good shape. That is why I like these Kindle books so much. There are no editorial alterations that I can find. The whole text has been preserved. These books are a joy to read both on Kindle and on PC.
