How to Take Smart Notes

Sönke Ahrens explains the note-taking method behind the prolific sociologist Niklas Luhmann: the slip-box, or ‘Zettelkasten’. Rather than collecting isolated highlights, the system links ideas into a growing web that generates insight and writing almost as a by-product. Ahrens makes the case that good note-taking is really good thinking, and shows how to build the habit. A favourite of students, academics, and writers, it reframes notes as a tool for developing ideas rather than merely storing them.
