When Not to Use Google
• Google doesn't cluster results• Google isn’t good enough to find a person's email
address• Google isn't the best place to find what an abbreviation
stands for• Some topic-specific directories are simply more fine-
tuned than Google's regular full-text search• When working on an in-depth research project (like a
college thesis), Google doesn't help you catalog multiple search results, or let you take notes on interesting sites.
Web Catalogues or Directories
Massive online catalogs that are edited, sorted, and organized by humans
