Hennings - Cell Division and Growth (Planaria) Project: Citing Sources

Why do we cite sources?

Why Do We Cite?

Citation acknowledges any source that has directly influenced your language, ideas, or arguments. You should cite not only what you quote, but also what you paraphrase. Putting an idea or argument into your own words may modify it, but does not make you the sole author.

In addition to giving due credit, citation allows your readers to locate your sources. Most formal writing is a dialogue with others who have addressed the same topic, and your reader needs to know who they are and where, exactly, you have encountered their ideas.

Also, if you don't cite, you'll be guilty of plagiarism and punished.

How to Cite:

The primary rule of good citation is to provide enough information so that readers can find the source themselves, if so inclined.

It is important to keep track of where your information comes from during the writing process. When you consult a source, make sure that you write down the complete bibliographic information, which typically includes:

  • author
  • title
  • publication or publisher
  • date
  • volume and issue numbers (if a scholarly journal)
  • page numbers

Different Styles:

APA Style

Created by the American Psychological Association, this style is commonly used in the social sciences. It uses in-text or parenthetical citations.

In-text Citations

Basic Info and Tips on In-Text Citations:

  • What's included in the parentheses?:  (Author's Last Name, Date)
    • Example:  (Jones, 1998)
  • Parentheses belong at the end of the sentence, but BEFORE the period.
    • Example:  Ms. Hooper is happy to answer any questions about citations (Jones, 1998).
  • If you state the author's name in the sentence, you will simply put the date in parentheses after the author's name.
    • Example:  According to Jones (1998), Ms. Hooper is happy to answer any questions about citations.
  • If there is no author, use the title.
    • Example:  Ms. Hooper is happy to answer any questions about citations ("Using APA," 2001).
    • Titles of books are italicized; titles of articles, chapters, and web pages are in quotation marks.
  • ​If there is no date, write n.d.
    • ​Example (Jones, n.d.)
