Those of you who keep up to date with  Book Briefing will have noticed that I quite often mention when American spelling is used in what I thought were British books. There's nothing wrong with American spelling, in several instances it makes more sense than the British version. My problem is that most of the visitors to this site are based in the United Kingdom. So, I use British spelling. Overexposure to American spelling can result in me failing to spot when there is an alternative British version I should be using. And then there are the word processing programs which automatically substitute American spellings and the danger of me failing to notice the change if I get too used to the "wrong" version.
