Last week, I did a post about the trouble I have with keeping up with characters, especially supporting and minor characters, over the course of a series.
Another substack I follow (Harvey Stanbrough) keeps a blank table/notepad open next to the work that he is doing. When he cycles back (reads the last few hundred or so words before starting the next section/chapter, he notes down people, places, significant events with the chapter or page number, so that he has a running tally and doesn't have to go back, unless he wants to read the exact description or something.
I'm not that awesome, yet, and that doesn't help already written work, like you are talking about here, but it might be a plan for the future.
