You can also use a search engine like Google . Just be aware of what information you are getting!!!!!!!!!
Ask yourself:
Who put this information here? (Might they be biased?)
What expertise do they have about this topic? (Are they a Ph.D. at a university or Joe-Bob in his basement?)
Why did they put it here? (Are they trying to sell something or convince me of a particular point of view?)
When did they put it here? (Is the information outdated?)
