The comma is the cause of so much confusion—odd, because it’s supposed to clarify writing. One of the main points of confusion, at least with my editing clients, is the series or serial comma, the pesky critter that goes (or doesn’t go) before the final “and” in a series of items.
The Chicago Manual of Style generally endorses series commas, and you’ll find that many books are edited with that style in mind (as is this blog). I have a profound comfort level with the series comma because that’s what I was taught. Magazines and especially newspapers, however, often follow the Associated Press (AP) Stylebook, which eschews the series comma in favor of saving space. In a publication that accepts advertising, the more text that can be fit in a smaller amount of nonpaid editorial space, the better.
I think many readers are being subconsciously taught AP style because so many people read magazines, newspapers, and their online equivalents in greater number and frequency than books. I also wonder if the public schools are no longer teaching the series comma in English classes, as I remember so clearly from my younger days. Certainly, many of my clients are mildly shocked or uneasy with the series comma. “Are you sure that goes there?” is a common question. Yes, I say, and then I explain why.
Of course, even AP style requires that a series comma be used when there is potential misunderstanding without it. Writers and editors who use AP style and who don’t fully understand the rules surrounding the series comma often err in these situations. If you use AP, it’s worth refreshing yourself on the stylebook’s comma rules.
In my wanderings around the Web, I’ve found an excellent resource for AP editing questions at the School of Journalism and Mass Communications, University of South Carolina. This article by Doug Fisher, from their August 2005 newsletter, is a wonderful reintroduction to the comma and its pitfalls: http://www.jour.sc.edu/news/csj/CSJAug05.html.
I especially like that Fisher references and endorses Bryan Garner’s exception to the comma after the year in an exact date. To explain, using Fisher’s example, a comma should be after the year (and the state) in this sentence: “Construction of the plant in Lima, Ohio, began on Aug. 16, 1984, and took six years.” The exception to the comma after the year is when the date or place is used as an adjective, e.g. (Garner’s example) “The court reconsidered its July 12, 1994 privilege order.”
No editor or writer should be without a good usage guide, and I am partial to Garner’s Modern American Usage, which you can find at the usual booksellers online and off. Garner has such a commonsense and thoughtful approach to English that I find myself reading beyond my original question, just enjoying the writing and the information. (I also used to read dictionaries as a child, so perhaps I’m just weird.)
(The title of this post is a play off the lengthy book titles from yesteryear and allowed me to introduce the comma in what is now considered an old-fashioned construction. See Chicago 7.132: “Old-fashioned titles connected by or are usually treated as follows: England’s Monitor; or, The History of the Separation or England’s Monitor, or The History of the Separation…”)
