Key Concept About Citation

You should cite resources that contribute to your work, both direct quotes and concepts and information you have summarized or used in another way. General knowledge or ideas that appear in all resources you consulted do not need to be cited. For example, Martin Luther King’s birth and death dates do not need a citation, but if you use his ideas about agape to form your own discussion, you need to cite King or the resource where you found his ideas.

Choosing a citation style

In addition to asking your professor which citation style is best for the assignment, you should ask for further detail, especially for graduate-level papers. Does the professor expect footnotes or in-text citations? Today, MLA uses in-text citations, not footnotes. If the assignment designates MLA with footnotes, you should ask for more clarification; perhaps Chicago style would be a better choice.

  • MLA – (Modern Language Association) – the simplest style; used in the humanities, where the date of publication may not be significant; citation with author and page appears within the text. If in doubt at Valpo, choose MLA.
  • APA – (American Psychological Association) – features dates prominently within the text because when a study was done is important; often required in these fields at Valpo: nursing, psychology, education, business, social work, or sociology. Names of the authors are often included within the text of a sentence: “Johnson and Lin (2001) examined whether passersby could differentiate between tap water and bottled water.”
  • Chicago – (Chicago Manual of Style CM) – uses footnotes collected at the end or the bottom of the page; Word provides a feature for insertion/deletion but not formatting. At Valpo, history, theology, or business classes may suggest this style, especially where there are many citations. This style allows you to easily add information footnotes as well as resource footnotes. Place a note number at the end of the citation, after the last punctuation. Number citations consecutively.
  • CSE – (Council of Science Editors) – includes two citation methods: can include the authors’ names and publication dates in parenthetical citations in the text like APA or can use superscript numbers matching numbered items in the bibliography. At Valpo, some classes in the sciences favor CSE; ask your professor which method to use within CSE.
