I long ago stopped reading books on note-taking.
They were always too vague and boring, full of platitudes that had little to do with the world outside academia.
I especially avoided “how-to” style books on the subject.
They would often list dozens of tips and tricks that had little to do with each other. There was never an overarching system for turning notes into concrete results.
But recently I picked up How To Take Smart Notes (affiliate link) by Sönke Ahrens. Ahrens is a Lecturer in Philosophy of Education at the University of Duisburg-Essen and also coaches students, academics, and professionals with a focus on time management, decision-making, and personal growth.
