When working on an assignment, you may find information in your research that you want to include in your assignment. You can use this information in a few different ways:
If you directly quote information or paraphrase it in your assignment, you must give credit to the original author.
Not only does citing information help you avoid plagiarism, but it is also a way for you to point your reader back to the information you referenced in your assignment. Being able to credit someone else’s work and direct readers back to the original source is one of the most important skills you will learn in college and take with you in your future career(s).
There are many ways you can cite your sources, often referred to as style guides. Different academic disciplines have created their own rules and guidelines for citing. The most common style guides for citing information in a written work include MLA, APA, and Chicago Style. However, disciplines like chemistry, medicine, journalism, law, and sociology have their own style guides. Your instructor will tell you which style guide they want you to use for your assignment. In other assignments, such as presentations, you can cite your source on your presentation slide or in a Works Cited slide at the end. In coding and programming assignments, if you use information from another source, you can include citation information in a comment. Always ask your instructor at the beginning of a course how they want you to cite information.
Remember, anything that is not your original work must be cited. This includes information from books, journals, newspapers, websites, videos, podcasts, presentations, interviews, social media accounts, even pictures!
One exception to the information listed above about citing is when you are using information that is considered common knowledge. Information is considered common knowledge if it can be found in many different places, is a noncontroversial fact, and the average person knows the information without having to look it up. Common knowledge can vary between cultures and disciplines. Examples of common knowledge include:
Common knowledge is dependent upon context, so make sure to check with your instructor when working on an assignment to know what they consider to be common knowledge and whether or not it needs to be cited. When in doubt, it is always best practice to cite the information!
Sometimes it can be difficult to determine when an in-text citation is needed. Below are some basic rules to help.
