[thelist] Directory Sites

[Paul Fisher]

I've got a client who's building a large directory site.  It's a directory
of businesses in a specific industry, with each business having their own
page on the directory.  It will need very good search facilities to allow
people to find exactly the right business.

He wants to see some examples of such directory sites.  Of course there's
Yell.com, but does anyone know of any other sites like this - in any
industry or topic?
