Zettelkasten Method

Zettelkasten Method

The Zettelkasten method is a powerful note-taking and knowledge management system developed by German sociologist Niklas Luhmann.

What is Zettelkasten?

Zettelkasten (German for “slip box”) is a method that emphasizes:

  1. Atomic notes (one idea per note)
  2. Explicit connections between notes
  3. Emergent structure through links

For formatting your Zettelkasten notes, see our Markdown reference.

aa.Luhmann produced over 70 books and 400 scholarly articles, attributing his productivity to his Zettelkasten system.

Core Principles

Atomic Notes

Each note should contain exactly one idea, making it easier to connect and recombine.

Connection-First Thinking

The value lies not in individual notes but in their connections. For a broader approach to connection-based systems, see our Digital Garden Guide.

Your Own Words

Notes should be written in your own words to ensure understanding and integration with your knowledge.

Implementation in a PKB

Implementing Zettelkasten in a personal knowledge base requires:

  1. A consistent note format
  2. A reliable linking system
  3. A method for discovering connections
