Folks, brace yourself for what might seem to be the most idiotic question you have heard in a long time. (taking deep breath e)Are there country specific editions of the OED that are published for selected populations of English speakers?

I have a dictionary on my desk and I am staring at it in utter bewilderment as I write. This is the ninth edition of the OED, and has the word prepone listed as an entry. It doesn't say anything about the origin.
tsuwm's entry above, about Indian English, sent me burrowing in the much ignored opening pages and sure enough, it says there, in an italicised blurb, that the edition is meant for sale only in the subcontinent. Books are relatively less expensive in India and friends travelling east always return with supplies for my shelves. This one is almost certainly, one such transatlantic traveller. Which brings me back to my question. And are there French, German, or Chinese editions too, apart from this Indian one?
