There are millions of websites out there on the World Wide Web. How do you know if it's a quality web site?
1. Authorship. Who wrote or created the content? Look for an "About" link to learn the answer to this.
2. Timeliness. When was it created? Some information is stable, like what countries were part of the Axis during World War II. Other information isn't, like the current economic or political statuses of many countries. So, while a website from the National Archives and Records Administration in 2005 about World War II has relevant information, a website about the government of Tunisia from 2008 isn't going to be correct.
3. Bias. Even without reading the "About" section of the site, can you detect a particular bias? Is the site encouraging you to believe something by using emotional language? Does it present an opinion or does it present facts?
4. References. Does the site present references or links to the sources of information it presents? Can you locate these sources so that you can read and interpret the information yourself?
