Regarding APA Style...until today, I've never lost points on an assignment for my referencing. My new professor is saying it's not correct to list an author more than once on your reference page if it's the same e-book textbook, despite the fact the information cited was from different chapters. I was taught to reference each chapter in my references...what is correct or were can I learn more about that? I couldn't find anything on APA's website specifically to that question.
