Can I continue to use the 2007 APA Style® Guide to Electronic References?
The sixth edition of the Publication Manual of the American Psychological Association, published in 2010, replaces the 2007 APA Style® Guide to Electronic References. That document was intended as an interim guide between editions of the Manual. The rules contained in it have been changed and expanded in the 6th edition.
The APA Style Guide to Electronic References, Sixth Edition, released in May 2012 and available in PDF format, offers up-to-date information on formatting electronic references in APA Style.
