Google generating URLs?

A Google search produces results from a "catalogued" Usenet search string

[Phil_Payne]

If I search on my name using google.co.uk one of the hits close to the top is not a real URL at all but a search on Usenet - if you click on it, Google actually does the Usenet search on Googe Groups.

The hit delivered in the SERPS is not a page at all.

Has Google "remembered" that Usenet query? The stuff you find is all about a famous libel case I was involved in back in 1999. It's a little bit of an issue because my email address and phone number have changed since then, so people looking for me are really being served obsolete information.
