I was recently browsing through books in a shop while I was on a layover at the Atlanta airport. One book I was looking at was the paperback edition of a hardback best-seller -- one of the more popular nonfiction books in recent years. And right there in front of me was a glaring typographical error on one of the pages I perused.
I'm not usually particularly good at noticing those types of errors. I don't have the copy editor gene, so to speak. But I don't think anyone can argue that in these days of massive upheaval in the publishing world that copy editing hasn't suffered greatly.
