So far, what I’ve settled on is something of a hybrid approach.
I have a set of notes that are the books of the Bible, but don’t contain the actual text. These are basically collection points for everything else related to a book study – sort of a note + MOC.
I have sections for a basic summary (title, author, date, number of chapters, background in a nutshell), key information about the book, key characters, keywords, and an outline. These aren’t necessarily filled in for every note, but they’re there.
Then there’s a header for notes on the full book, and a header for each chapter. (Some of the longer books are also broken into sections, so it’s easier to collapse them.)
These chapter headings are what I link to from relevant notes, and within these sections I also jot notes or questions relevant to verses in that chapter that don’t necessarily seem to warrant their own separate notes.
And I’ve recently added a second set of files that are just the text of each book that I can quote from for embeds using the AirQuotes plugin.
