Referencing is an essential part of academic writing. Its purpose is to acknowledge the original source of ideas and work that is not the author's own, and to point the reader to the original documents so that they can determine independently whether the attributed sources support the author’s argument as written.
To allow readers to trace a cited source quickly and accurately, researchers usually follow a certain citation style. The citation style you use depends on a variety of factors. Many disciplines tend to use one particular style over another (APA for psychology, for example). Your instructors may require you use a certain style, so ask what style to use before you begin your research. If you aren't required to use a certain style, use one that you are comfortable with and that best fits your needs.
There are several different styles of referencing:
