The Elements of Style

I have an old, yellowed copy of a previous edition of this book. I got the new edition with a view to assigning it as a required text in a college composition class, and I think it would be valuable for students. Handy for me, too. It's got all the basics. I refer to my Garner's Modern American Usage or the Chicago Manual of Style for my tougher questions of usage, but Strunk & White is great for “style” questions.
