Journals, professors, and disciplines often have their own methods for formatting citations. Many biology publications use the Council of Scientific Editors (CSE) style. The Manual is kept at the RIS Desk in the Learning Commons. The CSE Scientific Style & Format Citation Quick Guide is online. Other citation styles include the Chicago Manual of Style, Publication Manual of the American Psychological Association (APA), and the Modern Language Association (MLA) style, which can also be found at the RIS Desk. For help with Chicago, APA, and MLA citation styles, look at Purdue University's Online Writing Lab (OWL).
