… What Exactly Does An Editor Do? The Role Has Changed Over Time : NPR. (Hat tip, Dave Lull.)
I've done a lot of editing over the past half-century. Usually, it's pretty routine — tightening things up, coming up with a more efficient order. It can also be a pleasure. At The Inquirer I edited some real pros, and I knew what their prose sounded. Every now and then a phrase wouldn't sound quite. I would point that out to them, they would think for a minute, the tweak it. I copy-edited the late Stanley I. Kutler's Privilege and Creative Destruction for Lippincott years ago. Cleanest manuscript I ever saw. Maybe a comma got dropped somewhere. I don't recall changing anything.
