The “Zettelkasten” is a note-taking system invented by Niklas Luhmann, a German researcher who is considered one of the most important social theorists of the 20th century.
{% hint style=“info” %} “Zettelkasten” is German for “slip box” or “card index”. {% endhint %}
A Zettelkasten enables you to to organize your notes into an entangled web of information. This in turn allows you to discover new ideas and connections between your notes which otherwise would have been kept hidden.
The bigger your Zettelkasten grows, the valuable it gets: Imagine a Zettelkasten which contains thousands and thousands of ideas. If you now have a specific question and start to explore this Zettelkasten it will provide ideas which you’ve already forgotten a long time ago - thus it will probably answer your question in surprising ways.
The 12 Principles of a Zettelkasten¶
To make the most of a Zettelkasten, you should follow these 12 principles:
1. Atomicity¶
Each note should contain one idea and one idea only.
{% hint style=“success” %} This is key to link ideas. {% endhint %}
2. Autonomy¶
Each note should be self-contained and comprehensible on its own.
{% hint style=“success” %} This ensures notes
can be moved, processed, separated, and concatenated independently of its neighbors
remain useful even if the original source of information disappears {% endhint %}
3. Always link your notes¶
Whenever you add a note, make sure to link it to already existing notes.

4. Explain links between notes¶
Whenever you are connecting two notes, make sure to briefly explain why you are linking them.
{% hint style=“success” %} This is key to ensure you know why you connected the notes in the first place - even it is years down the road. {% endhint %}
5. Use your own words¶
Use your own words to express an idea, so your future me is able to understand it - even years later.
{% hint style=“danger” %} Don’t copy & paste! {% endhint %}
6. Keep references¶
Add the reference to the original source to your note.
{% hint style=“success” %} This makes it easy for you to revisit the original source later on. {% endhint %}
7. Add your own thoughts¶
If you have thoughts of your own, add them as notes.
{% hint style=“warning” %} Make sure you adhere to the principles of atomicity, autonomy, and linking. {% endhint %}
8. Don’t worry about structure¶
Don’t waste time thinking about a neat folder structure or preconceived categories.
{% hint style=“success” %} The Zettelkastens organization develops organically. {% endhint %}
9. Add connection notes¶
When you start seeing connections among notes, create “connection notes”. Their purpose is to link together other notes and explain their relationship.
10. Add outline notes¶
An outline note is a note that simply contains a sequence of links to other notes, putting those other notes into a particular order to create a story, narrative, or argument.
11. Never Delete¶
Instead, link to new notes that explain what’s wrong with the old ones.
{% hint style=“success” %} This way, your Zettelkasten will reflect your thinking over time. {% endhint %}
12. Add notes without fear¶
You can never have too much information in your Zettelkasten.
{% hint style=“success” %} The bigger your Zettelkasten grows, the valuable it gets. {% endhint %}
