In this Department, we regard copying and pasting from Internet sources or copying down passages from books as unfair and unethical. It is equally unethical to hand in a paper which you have bought from a website or paid someone to write for you, or to present work that a friend or relative has written for you as if it were your own. Consistently failing to state that you are quoting from other writers or using their ideas in a paper constitutes intellectual theft as well. We will take appropriate action if we discover that plagiarism has been committed; in extremely serious cases, this could result in expulsion from the university.
