Both are correct: From http://grammar.about.com/b/2008/01/21/questions-of-style-james-web-site-or-jamess-website.htm
Again, the authorities differ. With singular proper names ending in -s, insists the AP Stylebook, "Use only an apostrophe: Achilles' heel, Agnes' book, Ceres' rites"--a ruling upheld by the most recent edition of the Publication Manual of the American Psychological Association (APA Guide).
Not so fast, say most of the other guides. According to The New York Times Manual of Style and Usage (1999), "Almost all singular words ending in s require a second s as well as the apostrophe to form the possessive: James's; Chris's; The Times's."
And in this case, The Chicago Manual of Style agrees with the Times Manual. So does The Economist Style Guide (2005): "With singular words and names that end in s: use the normal possessive ending 's: boss's, St. James's, caucus's, Jones's, Delors's, Shanks's."
Most college writing handbooks also advocate the addition of s after the apostrophe--though The Blair Handbook (2003) does include an escape clause: "For singular nouns ending in s, it is always correct to form the possessive by adding both an apostrophe and -s. However, if pronouncing the additional syllable is awkward--as with last names that sound like plurals--some writers add only an apostrophe." |
