Whether you are using APA or MLA style, be consistent and use the same style throughout your citations.
Some students wonder why there are multiple citation styles. Different subjects use different styles because researchers are interested in different things. For example, APA is used more in science classes because it places a stronger emphasis on dates and currency than MLA.
The Southeast Reading Writing Center can help you with citation questions. The Writing Center has live chat and asynchronous (email) options to guide you in formatting your citations. They also offer multiple workshops you can attend for free that focus on APA or MLA styles.
