Evaluating Print vs Internet Sources - Tips from the Purdue Online Writing Lab (OWL).

It is okay to start looking for information using Google (or internet search engine of your choice). However, using Google Scholar can help you target more scholarly information. An added benefit to using Google Scholar is that it provides links to full text articles provided by the Purdue Libraries.

If you are off campus, you can edit the Library Links in Scholar Preferences so Google Scholar will continue to highlight the full text that is available through the Purdue Libraries. 

  • Go to
  • Click on the "hamburger menu" in the upper left corner (three horizontal lines)
  • Click on the Settings wheel at the bottom of the menu
  • Click Library Links
  • If Purdue is not in your list of Library Links, search "Purdue"
  • Select Purdue University -West Lafayette -Full Text at Purdue and Open WorldCat - Library Search

If you are expected to do a comprehensive literature search, you should consider using some of the scholarly databases provided by the Purdue Libraries.
