@Ragman,
I've got that. Don't agree with everything in it by now, but it's a classic.
The book my ex treated himself to is Fowler's Modern English Usage, 2nd edition. Haven't even opened it, but, it's there, just in case I want to check something. Ex was a lit major with mfa in theater, later a playwright; he considered that book as a prize.
A few weeks ago I was reading the 90th anniversary issue of the New Yorker - great issue - and in there, an editor who rose from a beginning editing job to being one of the top editors there mentioned that her favorite is Fowler. Now I may actually read some of it. I like the New Yorker editing in general.
I edited because I just remembered that it wasn't me who bought that..
