Thank you Paul, Ian, Fabio, Dan and Gary,

First, the good news.  It looks like the 2nd one is  “Concentration City” by J.G. Ballard and I am hugely thankful for your help with this.

Alas the first story still remains a mystery but the timecon.htm list is interesting.

My reason for asking about the first one (the planet-wide city is that a similar story has just appeared in an anthology of Danish SF (which I’ll be reviewing on <a href=”http://www.concatenation.org”>SF2 Concatenation’s</a> autumnal edition this September.  Of course there is nothing wrong with giving a good trope more than one airing.

Cheers

Jonathan

Title: If This Is Winnetka, You Must Be Judy
Author: F. M. Busby
Year: 1974

And there’s a list of publications.

On a related note, the theme of the global subway system was also used by Walter Jon Williams in Metropolitan in the 80s or 90s. I almost voted for it, but I read the post again and noticed that Jonathan read it in the early 70s. Interesting, though – was Williams directly inspired by Ballard?
