Reference is a relation between objects in which one object designates, or acts as a means by which to connect to or link to, another object. The first object in this relation is said to refer to the second object. The second object, the one to which the first object refers, is called the referent of the first object. When you write any paper, assignment, you are required to refer to the work of other authors. Each time you do so, it is necessary to identify their work by making reference to it— both in the text of your assignment and in a list at the end of your assignment. This practice of acknowledging authors is known as referencing. References must be provided whenever you use someone else’s opinions, theories, data or organization of material. You need to reference information from books, articles, videos, computers, other print or electronic sources, and personal communications.
