(no subject)

I have finished The Hitchhiker's Guide to the Galaxy. Slowly slowly I add to my geek cred on all those '100 books everyone should have read' memes. So now I know where Babelfish came from, and 42. OTOH I wonder at the lack of commas after apostrophes in this original paperback (which somehow has not fallen apart in the last 30 years.) Not the punctuation apostrophe, the other kind. 'What's happened Ford?' sort of thing. It's endemic. Is this a feature of Adams' style?
