Insights for How to Detect Plagiarism

  • If a student has copied text from a Web site, the easiest way to prove it is to search for the suspicious bit of text using a search engine. To do this, put the text in quotes: "Whether you think you can or whether you think you can't, you're right." (This one is actually from Henry Ford.)
  • Many of the free plagiarism-detection services only search the documents or Web pages that you specify. In general, the plagiarism-detection software that searches the entire Internet for copied information must be purchased.
  • If you think you've received work that has been copied, or if a detection service alerts you to this possibility, be sure to confirm that the attribution is actually missing (sometimes plagiarism-detection software won't be able to tell the difference). Also check to make sure that the work in question isn't, in fact, another copy of the person's work from a personal or school Web site.
