Forgive me for taking so long to comment and rate the paper you did.  I appreciated all of the work you put into it, but I had to redo and revamp the references.  They were not in
APA 6th edition style as requested.  I would've gotten marked off big time had I not revised it.  APA:

The source (book, journal, article, blog, etc) is always italicized;  following the source should be :  Retrieved from and here is where the url (if it is an article) goes.  If it is a book, then the title should be followed by the city, state: then the publisher.
