Simon Winchester, The Professor and the Madman

Simon Winchester, The Professor and the Madman. The story of the OED. I've always been fascinated and puzzled by the creation of dictionaries - how would you write the first one? Apparently, by reading every book and writing down every word and quotes of it used in every context. The story of the people who created the dictionary (an army of volunteers including one notable murderer and lunatic) was interesting, but I enjoyed the dictionary parts more. I think I read the wrong book, as the author has written another book about the venerable dictionary focusing on the work itself.
