There are different citation formats for different disciplines. Be sure to check with your professor about the appropriate format for your work before you start creating your citations. One format, MLA (Modern Language Association), a citation style commonly used in liberal arts and humanities disciplines, is discussed below. (See Purdue OWL's MLA General Format for Papers).
IMPORTANT:
Citation style guides are updated periodically, always remember to check your citations against the latest edition (or whichever version your professor requires) of the style manual you use for your research.
