I am writing an introduction of about three to five thousand words for a translation of a novel. In this introduction, my goal is to explain some of the context of the novel and briefly introduce the key themes within. There have been a couple of doctoral theses about the text and some other relevant work that provides a lot of useful information, so my temptation would be to use these in the introduction and include a list of 3-5 references with the introduction. Then again, it's an introduction, not an academic paper, and I also worry whether including quotations and references might be just a bit clunky for a short introduction. I could just ask the publisher directly what they would prefer, but I wanted to get a general, community sense of best practices first.
Should I include quotations and references in an introduction?
