Q. APA citations
I think you're on the right track My only comments are:
1. Be sure to be consistent in the capitalization of McPhee
2. I think the electronic communication from Bracciano should be set up as if it were a webpage since the communication wasn't to you personally and is freely available at the AOTA site. If you agree, then be sure to make the necessary adjustment to the in-text citation since you will have two citations with the same author and date. One will be 2009a and the other 2009b.
