A lot of the "classic" PKM approach to reading and note-taking revolves around extracting all useful information from a text, and not so much interacting with the text as text, paying just as much attention to its style, format, and authorial identity as its content. As a fiction writer, I have little use for extraction-first reading approaches, because so much of what I'm trying to absorb when I read novels and short stories specifically has to do with formal choices: it's stuff that really can't be put into other words.

There seems to be no real methodology a la the Zettelkasten or Sönke Ahrens' How to Take Smart Notes for taking notes on fiction. I wonder if this is simply because no one has taken the time to sit down and work a method out yet, or if it's due to a lack of research, or if perhaps there is a broader nebulousness to the goals and processes of fiction-oriented PKM that makes a unified system impossible: every reader and writer of fiction will have different things they find important, and thus every method will necessarily be different.
