I don't know how many regular readers of normblog will remember this post of mine from the end of last year detailing the lengths of Dickens's novels, but it gives a total of nearly 4 million words. Here is someone - Matthew Davis - who has made the effort of reading them all during 2012.
My own progress on reading the Dickens oeuvre slowed somewhat this year. The only Dickens I read was American Notes. I'll have to do better in 2013. (Via: ME.)
