The World Wide Web provides plagiarists with a rich library of material from which to gather information, but it also provides professors with a powerful to check sources and catch the word thieves. The laziness that prompts students to cheat can also prompt them to do a terrible job with their plagiarism. Being able to copy electronic source material rids them of the chore of retyping the paper, and some students don't even bother to proofread the results. These halfhearted efforts can easily be detected if you know what to look for. Context Change .
Students try to camouflage copying by changing the context of the original paper.
For example, I received a paper purported to be a draft information security policy for an institute in Korea. The references to Massachusetts law were, therefore, somewhat startling. It turned out that the paper was an almost complete copy of Harvard University's information security policy. Missing Footnotes . One technique that seems to appeal to plagiarists is to skip footnotes altogether.
