Subject
Directories
have arranged selected Web sites into subject categories and sub-categories.
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
(though the Library does not recommend searching the one at
www.yahoo.com as regular listings can sometimes be paid listings
with no indication).
The quality
of sites in a commercial subject directory are often good, though
most often you will have to evaluate them with as much rigor as you
would find from a search engine.
