A question to Mr, Armstrong

Sir, I have got a problem in writing a book report that I have not even recognised until now, which is in what part I can place the author's biography. I am thinking of showing the author's biography in order to detail the time when he lived. In the previous book report, I remember placing it "independently" of any other part, such as the Summary part or Analysing 7 Literary Terms part. I wonder if I can put it the same way as I did previously. Or should I put it not independently but in either of the parts, the Summary part, Evaluation one and Analysing 7 Literary Terms one?
