There are many, many citation styles for papers, and no one is an expert in all of them. In fact, very few people are expert in any of them. What is more important than mastering any one citation style is knowing where you can find information about the one you need. In college writing, MLA (Modern Language Association) and APA (American Psychological Association) are two of the most common styles. Chicago is another citation style (this is the style used with Turabian), as is CSE (Council of Science Editors). And we can mention APSA (American Political Science Association) and ASA (American Sociological Association). The Writing Center has the manuals for most of these styles, and we are happy to talk with you about the conventions and expectations of each. Remember too that the Little Tiger Handbook has sections for MLA, APA, Chicago, and CSE.
