This chapter presents the information and guidelines that will need to know about what and when to cite so that student can avoid plagiarism, both intentional and unintentional. Intentional Plagiarism is the kind of plagiarism most people think of when the subject is brought up: deliberate cheating on an assignment by copying a few sentences, a few paragraphs, or even an entire paper without quoting or citing the source. Self-recycling occurs when students reuse their own writing. Common examples include using a paper from a previous course in another course, turning in the same paper to two different instructors during the same term, or using portions of previously written work in new work. Plagiarism and copyright infringement both refer to violations of intellectual property standards, but the two violations are different. Plagiarism is an ethical violation relating to a lack of proper attribution for borrowed material. Copyright infringement is a legal violation relating to the misuse of intellectual property.
