Zettelkasten Method

Zettelkasten Method

The Zettelkasten (German for "slip box") is a note-taking system developed by sociologist Niklas Luhmann. He wrote over 70 books and 400 articles using this method.

Core Principles

  1. Atomic notes — one idea per note
  2. Unique IDs — every note has a permanent address
  3. Bidirectional links — notes link to each other meaningfully
  4. Your own words — always rewrite in your own language

The Two Types of Notes

  • Fleeting notes — quick captures, ideas in the moment
  • Permanent notes — processed, atomic, linked to the web of knowledge

Connection to Digital Gardens

The digital garden concept is deeply inspired by Zettelkasten. Instead of a linear blog, you build a network of interconnected ideas.
