Information on google is vast! You MUST evaluate your sources.
The free web is chock full of great information, but it can be difficult to sift through the sheer amount of results to find meaningful information that is reliable, accurate, and top quality. For that reason, be aware that you'll need to evaluate your sources with a more keen lens than you would with library sources.
Below are a few hints to becoming a more critical researcher, especially when you are searching the free web.
Use CRAAP detection to evaluate sources
Google can offer you, the researcher, a lot more than a simple results list based on a keyword search.
The basic Google search assumes AND between each word.
Use site to find certain types of sites, e.g., site: gov or site: edu
Use filetype to find specific formats, e.g., filtetype: pdf or filetype: doc
Use intitle to find sites where words are in title of the page, e.g., intitle: google search tips
This may help you find more relevant results
Use the advanced search to narrow your results using the above tips and more and get better results!
How to do it: click on the gear on the right side of the results page.
Wikipedia can be a useful site for finding information, however, it (along with other broad encyclopedias like WorldBook or Britannica) is not cited as a scholarly source.
What does that mean?
If you really love wikipedia...
I advise students to use wikipedia to find basic information. Later, after you've collected background information from better sources like Health and Wellness, you may chose to revisit wikipedia to find more sources in the referneces section of the page. By this time you will have developed your own expertise on the topic and will be better equipped to sift through wikipedia's information.
