Q. How do I cite something quoted in another source in APA format?
This is called using a secondary source. The rule for citing such sources is 6.17 on page 178 of the Publication Manual of the American Psychological Association, 6th ed. (available at the library's Circulation Desk). However, it is recommended that you find and use the original source of the quotation, if at all possible. Let us know if you need help doing this.
