Searching the
Internet
Most finding tools fall into one
of three categories
General Directories; Search Engines;
Specialised Directories
Many are hybrids
Directories - a large collection of links arranged
in categories.
The sites are hand-picked by human beings (payment
helps)
Sites are selective and categorised - The wheat not the
chaff
Size of database is small and based on the title page
(A
database is searched not the entire Internet.
2 - 3 million entries
typically in a directory (1 - 3 billion (US) in a search engine)
Web directories are designed primarily for
browsing and general questions
They are a good start whwen you have a
general question such as
'what is bird flu?' , 'What museums are
there in Pompeii', 'What's Goa like?'
Yahoo can be customised to become a
Portal
