You need to use a particular citation style that you must apply consistently throughout your paper. Sometimes, your instructor will tell you which style to use, other times you get to choose.
The two main citation styles used at TCC are:
APA, and MLA. However, some professors may request the use of CHICAGO STYLE
APA is mostly used in the Sciences and Social Sciences
MLA is used in many of the Humanities
Chicago style is the preferred style for History and Music
Each style has its own rules about how to cite specific sources. The TCC Writing Center offers help with citations. You can find more information on their website.
