I hope everyone has had a chance to read Tom’s brief essay on the drawbacks of using Google and Wikipedia for your academic research. To follow up on this topic, here is a recent article about faculty at Middlebury College banning students from citing Wikipedia.
Notice that the argument does not focus so much on the accuracy of Wikipedia articles, but instead focuses on the fact that college level students should not be referencing encyclopedias in their papers. Please keep in mind that encyclopedia articles, in whatever form, should be considered entry points in to the literature on your topic. In fact, most encyclopedia articles will include a list of sources. If you ever need help finding sources listed in an encyclopedia article, just contact the library!
