boolean and
Boolean ‘AND’

A

B

A&B

Example: “asthma AND exercise” yields pages that include both words

boolean not
Boolean ‘NOT’

internet directories
Internet Directories
  • Provide categorized lists of Web sites, constructed by humans (professional and/or volunteer editors)
  • Tend to be selective rather than all-inclusive (most aim for quality over quantity)
  • Usually include searchable database containing descriptions of the directory’s Web sites
  • Require some knowledge of subject matter
  • Some categories can quickly become outdated

      • Galaxy Medical List
      • Achoo
      • MedWeb
      • Hardin MD
search engines
Search Engines
  • A computer-generated index of all the infor-mation found on all searched Web pages
  • Aims to include all Web pages that contain the information, but without assessing quality
  • Takes you to the exact page on which the words you are looking for appear
  • Regularly updated by automated processes
