How To Find What You
Want
Directories vs. Search
Engines
Directories
• Lists of Web sites added
by a human
• May be general or
subject-specific
• Yahoo : general
• Kathy Schrock's Guide
for Educators : subjectspecific
Search engines
• An index built by a
computer program that
goes out and collects
data
• More inclusive than a
directory
• Keyword searchable
Successful Searching
•Combining terms is called Boolean logic
•Combine terms to both expand and limit
your search
•Most search engines have an advanced
feature that allows this
Boolean Logic : AND
Limits your search
Women & History
Only returns pages with both of
these terms on them
Boolean Logic : OR
Broadens your search
Women or History
Returns every page with either of
these terms on them
Boolean Logic : NOT
Limits your search
