Here are some links and helpful sites for citing your sources in APA Style:
Basic APA Style Guide handout from Chambers Library.
The OWL (Online Writing Lab) at Purdue offers examples and directions for citing sources in APA.
Pellissippi State College has a very useful style guide online (use the left-hand navigation to find a specific type of source.)
Finally, APA calls for a "running header" format in manuscripts, which can be difficult to set up in Word. The document below walks you through the steps.
