What is in-text citation?

The brief form of the reference that you include in the body of your work that directs your reader to the entry in the works-cited list.

  • Citation in prose means including the author's last name or the title (or descrip­tion) of the work within the page text and the page number at the end of the sentence in parentheses. 
    • Ex. Stephen King's On Writing is equal parts memoir and the author's advice on the craft of writing. 
       
  • Parenthetical citation means citing the original sources that appear in the text of your paper; use when you refer to, summarize, paraphrase, or quote from another source. 
    • Ex. According to Stephen King, his first attempt at being published came from "a literary agent and compulsive science fiction memorabilia collector named Forrest J. Ackerman" who rejected his story for Spaceman magazine in 1960 (35).
