Yahoo!
is an example of a commercial subject directory.
Yahoo!
has arranged selected Web sites into subject categories and sub-categories
and
has a search engine function.
But
beware! There are too many Web pages for any singular directory
service to organize. Plus,
you may have to click through categories and subcategories to get
to useful information.
