We highly recommend visiting the official APA Style Blog written and run by the folks at APA (APA style experts). The contributing writers of the blog (who use the APA style daily in their work) publish weekly posts on every aspect of APA style one can think of. Questions posed by students, faculty and writers who need clarification on the finer points of the APA style are answered by the bloggers. They even have a Facebook page where student questions are answered.
