A citation is the documentation you provide about where you got specific information or ideas. You need to include enough documentation about each source so that a reader can find these sources on their own. (This means that, in academic writing, we need to include more than just the link!) Usually you incorporate this information as in-text citations (or hyperlinks on web sources), footnotes, or endnotes.
You will often be asked to compile a list of citations for the sources you've used at the end of a research paper or other assignment. Depending on the citation style you use, this list is called a "Bibliography," "Works Cited," or "References" page.
Your instructor may ask you to use a particular citation style, such as MLA, APA, or Chicago. Citation styles provide guidelines that help you present citation information with consistent formatting and punctuation. If you need to look up guidelines for a particular citation style, our Citation Help page can direct you to various print and online style manuals. We also recommend the Purdue OWL for helpful guidelines and examples. Since different disciplines tend to favor some citation styles over others, check with your instructor to see if there is a style you should use in their class.
Any time you reuse, reference, or make a call out to someone else's ideas or work you need to add a citation. Usually this includes any time you include direct quotations, paraphrase an idea, or summarize someone else's work!

On our Video in the Curriculum and Podcasting and Audio in the Curriculum pages we have resources to help you think through these topics, such as:
