When writing any type of paper for class, you will probably refer to the intellectual work of others as support for your own ideas, arguments, and assertions. As you do so, principles of ethical behavior and of academic integrity demand that you give credit to the originators of the ideas or specific sentences and phrases you use.
The reason that academic papers require the use of highly detailed methods of making references to the work of others is to avoid the risk of seeming to pass off the work of someone else as your own work. This is one way of defining plagiarism. You should take a look at the library guide Academic Integrity: Resources for Students & Faculty to learn more details about academic integrity and the University's policies.The following tutorials will go further toward introducing you to the intersection of academic integrity and citations and references.
