"Autobiography of Mark Twain," published a full 100 years after its author's death

The 736-page "Autobiography of Mark Twain," published a full 100 years after its author's death, was a surprise bestseller when it came out earlier this month.

That's terrific news for the University of California Press, the book's publisher, which says "Autobiography of Mark Twain" is the biggest seller it's ever had.

Original plans called for a printing of 7,500, which was upped to 50,000 by the time the book actually went to press. It's since gone back again and again, bringing the total number of printed copies to 275,000. But still, it is hard to find -- as the N.Y. Times reported Friday, the book is selling so fast that it's selling out.
