The Handbook of Good English

As a professional advertising copywriter and English major, I have all the authoritative books on grammar, punctuation and usage, but "The Handbook of Good English" is my go-to source. (My major professor turned me on to it years ago; I just ordered a new copy to replace my original, which was borrowed and not returned.) Highly practical, eminently readable, easy to use and understand, and far more comprehensive than Strunk & White's "The Elements of Style," this is the one book everyone who writes for a living or just writes, period, should have it on their shelf.
