Past surfing

I’ve just started reading again a Readers Union edition of John Brunner’s oddity Stand On Zanzibar. No date of publication on offer but it’s 500+ pages in hardback and originally published in the UK in 1968 for a modest £2.10! So the RU edition must be dead old.
    It’s is all about the horrors of the 21st century, according to the blurb in tiny print on the front fold of the dust jacket. I wonder if the horrors include predictions of Bier Smarmer, Edstone Milipede, Jonah Burntbum and all the rest?
