Yahoo
is an example of a commercial subject directory. Subject directories
are collections of Web sites that people have selected and organized.
They
have arranged selected Web sites into subject categories and sub-categories.
The
quality of sites in a subject directory is usually good.
Sometimes
links are annotated so you'll know before clicking on it what a
site contains.
Many
commercial subject directories, such as Yahoo, also have a search
engine function.
