CSULB's Style Manual and Citations Methods is a good starting point. The American Psychological Association (APA) citation style is frequently used for Freshmen engineering courses since there is no standard style that covers all of the engineering disciplines.
As you progress in your program, you will use the citation style developed by the appropriate professional association for your discipline (e.g. mechanical engineers use the ASME citation style). See the section: "Guides to engineering citation styles."
