I'm really looking forward to getting a copy of this. Co-authored by Ammon Shea, who recently read the OED cover to cover, if you can believe that. I'll be talking to him about it for an upcoming Errata post.
This is a remarkable book. And some of the words are truly disturbing. I remember one referred to a particularly gruesome effect of extreme constipation that still makes me queasy. (I seem to have blocked the word itself, thankfully.)
