Zettelkasten is a German word that roughly traslates to “slip-box.” Not everyone agrees to this translation. It is a note-writing system famous for fuelling the scholarship of Niklas Luhmann. sonke ahrens’ book How to Take Smart Notes - Ahrens is considered the best entry point book for the system in English. I think the most intuitive version of the system for the Internet age is Andy Matuschak’s Evergreen note-taking system. Many consider the website Zettelkasten as the best source of practical information on modern-day applications of the process.
My own version of this system is talahardin.
