Information specialist, Phil Bradley has compiled a very useful guide to finding information with search engines.
The chart is divided into two columns: What do you need to find, and what do you already know? and then tells you What is the best resource to make use of?
For example, when you want a quick factual answer, Bradley lists several search engines, such as AskJeeves and Brainboost, that can provide it. Or if you want people’s opinions on a subject, try Google Groups or Daypop. Bradley also notes which search engines offer RSS feeds for your searches.
This is a great resource for those who can’t keep all the different search engines straight; So, pretty much everyone, I guess.
