I take up a text, scrutinize it for errors. I root out as many cliches as I can, make the imprecise more exact, prune judiciously, recast maladroit constructions, enforce house style when reasonable, and try to leave what is OK the hell alone. I'm there to protect the writer and the publication from carelessness and embarrassment. Usually I succeed. Despite the occasional, and inevitable, oversight or blunder, for thirty-eight years I have left those texts better than I found them.
