Knowing how to cite another person's work properly helps you to:
give credit and acknowledge their ideas
direct readers to the sources on which your research is based
ASA style (created by the American Sociological Association) is a widely accepted citation style used for writing university-level research papers in the discipline of sociology. The Department of Sociology has created their own guide, based on ASA style, which is available on the Department's website: http://www.queensu.ca/sociology/about-us/style-and-reference-guide.
