The Turnitin study follows a recent report by the Pew Research Center that shows growing concern among college presidents about the issue of plagiarism. Of the 1,055 presidents surveyed, 55 percent believe that plagiarism is increasing in their institutions while just two percent believe it is decreasing. 

The new Turnitin study examined 128 million content matches from 33 million student papers that were submitted to Turnitin between June 2010 and June 2011. The study uncovered the most popular categories of content used in student papers.
