A citation is a way to tell people that an idea, words, or picture, came from someone else. It is a way of referring to the original work; it tells your reader or audiencewhere you got that idea, words, or picture from.

The word "reference" is often used interchangeably with citation. It means the same thing. You are being asked to refer to wherever the information came from originally.

A bibliography is a collection of citations or references, usually at the end of a work.

In Western culture, we believe that ideas belong to the creator. Their ideas may come in different forms, whether written, spoken, or visual (like a piece of art or a photo), but it's still their idea. We give credit to those individuals who created the ideas originally. If you don't give credit to who the creator, that's stealing someone else's work  and it's known as plagiarism. 

Citing is how we give credit. But besides giving proper credit and avoiding plagiarism, there's a number of reasons why a person should cite. 

• To provide enough information that your reader can go find the original source if they wanted
• To show your reader you've done proper research and got your material from reliable sources
• To show professionalism in your work by following formatting standards

Just like there is a specific format to writing a resume or a letter, citations have specific formats or "styles" as well. These styles set a standard for how to cite and where to put citation information in a paper.

These styles are developed based on the need of the creators, and they usually have slightly different focuses. Some of the most popular ones include:

• APA - From the American Psychological Associate, it's usually used for social sciences, business and nursing
• MLA - Modern Language Association style is often used in the humanities, like art and literature
• Chicago/Turbian - This style is often used in the humanities as well
• ASA - America Sociological Association style is often used in sociology

There are more styles than this, and you can find out more about them on our Citations Guide.
