The University has acquired a new software tool for you, and it looks awfully good. I urge you to take a look at it. It's called "Riverpoint Writer", and it helps you to format an APA version 6 paper correctly. It even takes most of the pain out of constructing the reference list. You can learn about it by going to this address (if you're currently logged into the University system):
If you have ever used APA Perrla software, this will seem familiar, because it does much the same thing. But, unlike Perrla, this is now free to University of Phoenix students and faculty.
