For sociology projects and essays, you're typically expected to use one of two styles, ASA or APA. Check with your professor to learn which s/he wants used on a given assignment, then consult one of the following resources.
ASA (American Sociological Association) style
APA (American Psychological Association) style
You can also use RefWorks to organize references you collect while conducting research, cite the references in your essay, and compile a bibliography according to the citation style of your choice. Open RefWorks to get started, or consult our RefWorks Guide for more information (including the Group Code for CSULA).
