“Please take back out every Oxford comma,” a journalistic-minded author of mine once said. I began my editing career using Associated Press (AP) Style, so I understood his suggestion, but the house style at my current company mandated the use of the serial comma. We had a short, spirited, and (thankfully) respectful debate about it, and ultimately house style prevailed. I convinced the author that the meaning in his writing remained unchanged and using a serial comma accomplished something important to the company—it maintained consistency throughout their titles.
