Your professors will tell you which style they prefer you to use when writing your papers. The publishers of the three major styles, below, do not offer complete guides on the web, but OU has purchased access to the Chicago Manual of Style. The best place to go for further help is the OU Writing Center. 

The American Psychological Association (APA) Style Blog and the Purdue Online Writing Lab (OWL) can help with APA Style, used chiefly by disciplines in the social sciences.

The Chicago Manual of Style has an online edition. (OU login required)

The MLA Style Center and the Purdue OWL supplement the 8th edition of the MLA Handbook.The MLA (Modern Language Association) style of formatting and citing is used primarily in language and literature departments.

There are print copies of the style guides behind the Information desk and on reserve for use while in Bizzell.
