Citation Styles

Each course may require a specific citation style.

A citation style is merely a set of conventions established by a particular professional academic organization to make providing references simple and clear. The goal of any citation style is consistency, but each has its own idiosyncrasies that must learned. Three of the most popular, and their official style guides, are

  • MLA: Modern Language Association,
    MLA Handbook for Writers of Research Papers
  • APA: American Psychiatric Association,
    Publication Manual of the American Psychological Association
  • CMS or Chicago: University of Chicago Press, Chicago Manual of Style

While these official style guides are the only place to get the full details for every citation situation and for answers to specific questions about formatting in each style, all three have been summarized in a number of handbooks and websites. Unfortunately, not all summaries are accurate or up-to-date, so you will find inconsistencies on various websites, in various books, and even among your own instructors, who may well modify one of these styles for their own classroom use.

As noted, the Adelphi libguides’ citation guide provides links to summaries of the three styles above, but if you are ever in doubt about what citation style to use, simply ask your instructor.
