These are more likely to return sites from credible sources. They save time by automatically filtering out poor quality material so you don't have to.
Use Internet Sources when:
You are prepared to evaluate the credibility of what you find
Much of the internet is opinion, undocumented, or otherwise not suitable for academic research. While good information can be found on the internet, it is mixed in with poorer quality material. Be prepared to spend time weeding the bad from the good.
You need Popular Culture or very current information
You know the website you are searching is credible
See Evaluating Web Sites above, or use one of the recommended Search Engines on this page.
