Overview and Contradictions

Research-based writing in American institutions, both educational and corporate, is filled with rules that writers, particularly beginners, aren't aware of or don't know how to follow. Many of these rules have to do with research and proper citation. Gaining familiarity with these rules, however, is critically important, as inadvertent mistakes can lead to charges of plagiarism, which is the uncredited use (both intentional and unintentional) of somebody else's words or ideas.

While some rhetorical traditions may not insist so heavily on documenting sources of words, ideas, images, sounds, etc., American academic rhetorical tradition does. A charge of plagiarism can have severe consequences, including expulsion from a university or loss of a job, not to mention a writer's loss of credibility and professional standing. This resource, which does not reflect any official university policy, is designed to help you develop strategies for knowing how to avoid accidental plagiarism. For instructors seeking a key statement on definitions and avoidance on plagiarism, see Defining and Avoiding Plagiarism: The WPA Statement on Best Practices.

(Purdue University students will want to make sure that they are familiar with Purdue's official academic dishonesty policy as well as any additional policies that their instructors have implemented.)
