The Zettelkasten (German for “slip box”) is a personal knowledge management system popularized by the sociologist Niklas Luhmann.

Core Principles

1. Atomic Notes — Each note captures a single idea
2. Connections — Notes are linked to create a web of knowledge
3. Unique Identifiers — Each note has a permanent ID
4. Own Words — Ideas are rephrased in your own understanding

How It Works

The Zettelkasten method works by creating small, atomic notes that capture individual ideas. These notes are then connected through links, creating a network of knowledge that grows organically over time.

Types of Notes

1. Fleeting Notes — Quick captures of ideas
2. Literature Notes — Notes from reading
3. Permanent Notes — Distilled, atomic ideas
