How come the site I was after (http://www.pataphysicsmagazine.com) was
not picked up by the google search engine?

One issue is that there appears to be no sites that link to this site
(at least not any that are already in Google's database). To see this
for yourself use the 'Find pages that link to the page" search on the
Google advance search page
<://www.google.com/advanced_search?hl=en>. This would mean that
the Google web spider ("GoogleBot") would have no way of finding this
site by following links from already known sites. To help Google out,
let them know about this site directly by going to
