Citing Sources


There are varying ways to cite sources. Usually, a short form of the citation is included within the text of the paper (referred to as in-text or parenthetical citations) and then the full citation is given on the last page of the paper, sometimes referred to as a "Works Cited" page, a "Reference List," or a "Bibliography."

Also, there are different styles to citing sources. The following styles are commonly used:
  • APA (American Psychological Association) Format is generally used to cite sources within the social sciences and sciences.
  • MLA (Modern Language Association) Format is generally used to cite sources within the humanities, liberal arts, and business studies.
