Some stuff explicitly no longer canon. Other stuff which I no longer even know if it's canon or not. Stuff so sloppily and messily done I have no reference point for whether it's useful to note or not. A complete lack of organization, consistency, or generally any coherency.
Keep in mind this novel dates back to 2009. I've been writing it for 8 years now. And I've revised it over that time so many times. And some notes refer to some revisions, others to other revisions, and it's just a whole chronological mess. So many conflicting ideas. Plot-wise. Character-wise. Setting-wise. Everything is just the biggest mess possible. And I need to sift through it all, manually, step by little baby step. In order to tell what to do with it.
What I want is for my notes to have a strict organization. Concepts, background, novel history, trivia and the like in one section. Worldbuilding in another. Backstories (which're intimately tied to the worldbuilding in that several key characters have ancestral ties to those that effectively built the world) separate from that. A section detailing every character, every facet about them. A section outlining the plot start to finish. Plus a section for orphaned material: little tidbits here and there which may or may not be things I can (re-)add to the novel.
It's so much work.
And it's so disorganized.
I don't know if my brain can actually make the connections it needs to in order to pull this off.
Yet I know that if I don't do this, I can't pull it off.
