Purdue's Online Writing Lab (OWL) provides a wealth of information about how to write good papers. OWL includes information about APA, MLA, and Chicago manuals of style...so you should be ready for an assignment in any class.
When you refer to an information source in your work, it is imperative that you correctly cite the source. Why?
There are many different style manuals on the market, such as Modern Languages Association (MLA), American Psychological Association (APA), and Chicago Manual of Style. Here in SCI 360 we'll follow the APA style guidelines for the sake of consistency (and because the APA guidelines are conveniently located on the OWL website).
