Parenthetical citations

How to Document Sources in the Text of Your Paper

Most teachers and professors require parenthetical references to document your sources. There are 3 ways to use them:

1. Cite the author's last name and the page number(s) of the source in parentheses. Note that there is no comma, "page", or "p." in the parentheses. Also, notice the period goes after the parentheses.

One historian argues that since the invention
of television "our politics, religion, news, athletics,
education and commerce have been transformed into
congenial adjuncts of show business, largely
without protest or even much popular notice" (Postman 4).


2. Use the author's last name in your sentence and place only the page number(s) of the source in parentheses.

Postman points out that since the invention
of television "our politics, religion, news, athletics,
education and commerce have been transformed into
congenial adjuncts of show business, largely without
protest or even much popular notice" (4).

3. Give the author's last name in your sentence when you are citing the entire work rather than a specific section or passage, and omit any parenthetical reference.

Postman argues that television has changed virtually
every aspect of our culture into a form of show business.
