Spot the error? (If you can’t, it’s to do with a missing apostrophe.) In defence of the publishers, Wiley, this book doesn’t come out until April 2007 so there’s time to fix the cover. Presumably their authors do know how to write; perhaps it’s their designer who doesn’t. (That’s an ugly sentence, but I’m showing off two apostrophes.)
Or maybe they think there’s no need to bother with apostrophes in the digital age…

My word, that’s appalling.
Someone was telling me yesterday that Sweden abolished the apostrophe at some point … I sincerely hope we’re not heading the same way.
