Any time your work contains or refers to someone else's ideas, words, images, media, or sounds you need to include a citation.
1. In-text citations should be inserted at the point of use in your assignment and indicate that the information you just presented came from a source other than your own brain or common knowledge.
2. A Works Cited or References section should be included at the end of your assignment.
3. In Works Cited / References, list all the works you referred to with in-text citations in the body of your assignment.
4. There are many citation styles, each with it's own precise formatting. The most popular at Clark are MLA and APA.
