What is a parenthetical citation?
A parenthetical citation is one that appears IN your paper; it provides the reader with the author's last name and page number (for a book or article) or article title (if no author is specified). This is the C in ICE'ing quotes.
The easiest way to do a works cited page is to use one of the MANY online resources. EasyBib is one such source.
