Many types of plagiarism exist; some are obvious and some are not. A writer must know what constitutes plagiarism because ignorance of the facts will not excuse him or her from the consequences. The University of Pittsburgh's undergraduate plagiarism policy (University of Pittsburgh, 2008) lists examples of plagiarism:
The best defense against plagiarism is knowledge and the practice of effective writing skills. Learning how to paraphrase, quote, and to properly cite and reference material is critical. A writer will never gain good writing skills if he or she does not create their own work. Not procrastinating and beginning papers early will help to squelch the temptation to cheat by plagiarizing. The writer's academic, professional, and personal reputation is too valuable to lose over a moment of laziness or weakness.
