Zettelkasten Note-Taking Method: Simply Explained

[@littlecabinknits7135]

As a German who studied Luhmann's Zettelkasten system, I can say, this was an excellent explanation of all aspects, especially pointing out the common misunderstandings and explaining them right!

[@ShuOmi_Official]

Wow thank you! I'm so happy to hear this.

[@AndersJackson]

It is Zettelkästen, isn't it?

[@dahzinho]

@@AndersJackson I think that's the plural form of the word

[@dalnoob]

@@dahzinho yes it is

[@alessazoe]

Also finally someone pretty much nailing the pronunciation! Most foreign speakers get the z sound wrong, pronouncing it too soft.

[@overthemoo]

This is exactly what I have needed. Just went back to college a year ago, and I enjoy my classes but the last 2-3 weeks become insanely stressful. I knew there had to be a way to take notes that would benefit my scattered way of absorbing and recalling information, but I had no extra time to work it out. This seems perfectly appropriate.

[@ShuOmi_Official]

Glad to hear this! Hope your studying is going well at college!

[@johnnygorena5318]

But where do you go to get zettkekastin I can’t find it anywhere…., it’s this like Remnote or Anki type apps I know all have they own characteristics

[@EmpressCosplay]

As a German, I am SO happy that you pronounced Zettelkasten properly! Good pronounciation of the sounds, and, more importantly, not over-exaggerated (it can be borderline insulting sometimes, really!). I just appreciate it so so so much. Also, amazing video! Your visualisation of the principles is on point.

[@ouioui8593]

Using the correct spelling of "Pronunciation" is also important 😊

[@EmpressCosplay]

​@@ouioui8593Whoops, haha, didn't even notice that, thank you for pointing it out! I always strive to improve my 3rd language, it's a work in progress 😂 Though my point still stands that I am very happy about his effort to pronounce it properly. Even if it were not 100000% perfect, we still can see the honest effort, and that's always really respectful and lovely to hear.

[@asquirre]

I've been searching for this method for years. Almost fully developed the system myself but I'm glad that it's been successfully ironed out

[@mariap.2822]

Finally a video that explains this succinctly and accurately. There is so many 1 hour long video where people just talk how they are implementing what they think Zettelkasten means... Congrats!

[@ShuOmi_Official]

Glad it was helpful! Thank you Maria :)

[@PringlesOriginal445]

Thanks for explaining. I came across this method last night and I started it and I have to say it is definitely AMAZING. The way you can keep making sub notes to add to the main idea is really helping my brain make connections, unlike mind maps which NEVER helped me because it all felt muddled. Hopefully I stay organised with it, but I've organised them like this. First I give the whole section a topic number e.g 3) Knowledge from reason. I label every card from that section with that same number. Then for the topics from that section I use 3a. A priori/ A posteriori Or for next topic, next card or set of cards, 3b. Necessary and contingent etc etc And then when I find an idea/point that I want to add to the sub topic I was studying and completed notes for already or thought I had fully understood, I label that card 3a1. Or 3a2 or 3b1 or 3b.2. The genius is in this step, because you can just go back and keep adding more and more examples, points, analogies, questions that been answered which clarify that main 3a) sub topic card. It's a wonderful system!! I feel like I found my perfect system to study for my exams, I have always struggled with note taking and this just seems concise and captivating enough, to organise my thoughts and store them in a way I can access and add too later, which I always felt unable to do with just paper alone. I am gonna put all my notes into digital format aswell, but yes. I'm super happy. And I use the feynman technique to review the card or review the topic before making the cards so I really know what I'm talking about :P I'm finally using all the flashcards I've had stored in my room for years! Lol. Flash cards never appealed to me because of their unorganised nature, but now that I can easily organise them it honestly is wonderful! If only they thought you these things in school! I'm 22 now, with the hopes of going to uni after being out of school for a few years. :)

[@ramanan86]

You’re going to do amazing at anything learning endeavour by just having this type of mindset. Now add actual techniques and tools like these and you’re going to destroy university. I never made the best out of my time at university but I didn’t have the mental maturity to pick up new techniques even when my subpar “cram” system was clearly not working. Good luck internet stranger! Best of luck! 😀

[@realisticrealist3267]

30 yrs in Germany and I hear this system for the first time 😅 Thank you for this video! When I went to school we had "Karteikarten" ... Mainly for learning vocabulary but also such index cards with information about a topic (e.g. in biology). Nowadays you can keep the same information on your tablet or even your phone 😂 But I will always prefer the feel of real paper 🙂

I am also binding my own journal ...you video helped! because it means I can remember more...something like that brings in more hope, and some light. it helped me not sit in the dark, even for a little while. and I am sorry if this is TMI or being rude talking about something else.. but I truly wanted to leave a line or two, of gratitude ..thank you

[@geraldlandis8818]

Gentle professor teacher.. that is concise

[@isseyfujishima9673]

I've become curious about this method, so thanks for the introduction, even if I didn't grasp it fully yet. I especially like that you pronounce the German word Zettelkasten beautifully and accurately (the 'Z' being pronounced as 'TS'), and it's a pleasure to listen to you in general.

[@t0dd000]

Lemme start this off with how much I love this video. Thank you for all the work you put in. This is a great service to us all. I just wanted to have a discussion about how the Bibliographical Slip Box is so inconsistently described by so many blog posts and videos on the topic. And almost everyone avoids discussing how it is done on paper. So, hear me out please. But it is important to note that this is not a religion. We can all vary our approach. Ahrens calls the notes in that slip box "literature notes" and "reference notes" interchangeably (he doesn't have them separated as you do in your video) and just like with the "term" permanent notes, he almost always uses those terms as descriptions not labels (not really "terms" per se)-i.e., lowercase "literature/reference notes" and lowercase "permanent notes" (cuz, literature notes are ALSO permanent notes, Ahrens, chapter 6, p42). I call the notes in the main slip box, Main Notes or just "the notes in the main slip box". Anyway. Ahrens is particularly vague (and sometimes contradictory) on this topic in the book. Luhmanns put all his extremely brief literature/reference notes on one side of a card and included a very brief bibliographical reference there. Then he put the full bibliographical into on the back of the card. Ahrens describes it vaguely in section 1.3 and then quotes exactly what Luhmann says he did in section 10.1, paragraph 5. That being said. Luhmanns and Ahrens don't advocate one method for the mechanics of the thing as long as you are consistent and follow the principles. I like Umberto Eco's terminology even better: Reading Index Cards (Reading Notes) and Idea Index Cards (Idea Notes). So, I suppose what I am getting at is that every description I see of Luhmann's methodology gets hand-wavy on the topic of reference notes. Primarily because there is no one source that I have found in the English language that definitively describes how he structured these precisely. I had to read, re-read, look at photos, even take notes, etc. I am certain many of the folks coming to this video are having the same issue. All that being said, I like your spin on the concept. Literature Notes and Reference Notes as two steps in the process instead of one. Personally, I keep a document I call "Reading Summary" (or just "Summary"-a one-context document) that feed into my "Reference Notes" and "Main Notes". They start off as fleeting literature notes (as Ahrens calls them) and then I edit them down to something more sensible: "Fleeting Notes" and "Fleeting Literature Notes" ⟶ "Reading Summary" ⟶ "Reference Notes" and "Main Notes" (or the more Eco-ish, "Reading Notes" and "Idea Notes"). . . . Oi. That was a lot longer than I intended. Great video. You really nailed the nuance of the method, especially the core principlies, that so many struggle to articulate or miss completely. I.e. You truly capture how the method is different, like really really different. Great job.

[@treyunderwood5463]

[@gracedingal222]

I used to teach at a university and I noticed a trend wherein my students who graduated with Latin honors are the same ones who took down notes by hand. I usually give essay exams and I pretty much can read myself while checking and grading their papers.

I am so glad to have come across your videos. I have recently become obsessed with zettelkasten. I even created a zettelkasten while learning about zettelkasten. I thought that would be the best proof of concept to decide if it's something I wanted to incorporate into my self guided learning. So far I like it. I found your video clear on the basic concepts. I have read a number of article on zettelkasten but I think any one said to keep the reference cards in a separate box from the note cards. Good idea. BTW. All your other videos look really interesting and I hope to watch them soon. Keep up the great work and stay safe.

This method was not invented by Niklas Luhmann. The same method has been used for centuries by scholars in several countries. A famous one was Umberto Eco, writer of several novels. I guess Luhmann only became associated to this method because he popularized it, but many research methodology books will explain the same ideas.

[@erlinacobrado7947]

True. Hegel used it, centuries before Luhmann.

I honest to god don't understand it eventhough I watched the video 4 times and tried creating notes out of it. Maybe it's because I'm a little slow. World is a difficult place to navigate when you're slow.

[@justtekina6709]

[@jjpanda]

thank you for the clear and informative video! i wonder if this method can also be applied for science-based subjects like chemistry, biology and physics?

[@ivanaerenda2205]

Yes. Think of it as a way of gathering all your subjects/notes on one particular topic, i.e. topic: atom bonds, more info you could find in notes on molecules, or some biology notes of celular life cycle, aticles of a newly developed medicine in pharmacy, ... not only in diff.branches of chemistry. This method is basicly very funneld info about some topic you already know something about and now you are deepening and/or widening this knowledge from diff perspectives.

[@becominggold96]

Thank you for this video. If I'm reading textbooks for school, do I need to make a card for each chapter/unit or should I continue to just write my notes in my notebook and only use some of my notes on a card that covers just the main ideas? Also, why is the bibliography card necessary? Is that just for someone who is publishing their work or do you recommend everyone do that as well, students included?

The first step is creating fleeting notes before the literature notes

[@alScotlandi]

If I have 20,000 notes for example. How do I remember the previous notes to connect new ones with them? ie how do I remember what is on card 2,345 and that it connects with my note 20,001?

[@offTheMedsYe]

Great job giving an overview of the method in such a short amount of time. If I may offer some constructive criticism, I think you glossed over the indexing part a bit too quickly, as it's a contributing factor to be able to retrieve relevant notes at a later time. Zettelkasten IDs as implemented by most software for that job (like zettlr, the archive or obsidian) contain some sort of timestamp, instead of just numbering your notes.

[@lukaszbe5674]

I am currently looking for reliable indexing procedure for my notes after switching to obsidian. Can you refer for some marerials?

[@YlmazDALKIRANscallion]

[@DonDealio]

There is some confusion out there about terms being used in all this. The term "fleeting notes" is also being used. To me those are the quick first-hand notes about one's ideas and understanding, when going through the material or right after. Is that what you are calling "Literature notes"?

[@MosesGTC]

I am learning. It's quite hard to understand actually. Basically, it's using questions, themes, to point to tags which contains other related tags and notes? The act of linking tags is manual and by doing that help the brain to make connections? Wonder how will it look like using this system on Evernote.

[@michaellwalker8748]

This is precisely why I'm here.

[@romanrey9055]

Yes you can do this in Evernote. Try this: Create a Zettelkasten notebook. Then start making a note for ideas that are important to you - those can be new or old, your own or somebody elses. Explain the idea in a few sentences, but try to be short and to the point. Then add some info like who the idea is from and a source, maybe a book or a link. Now to the important part: Look through your existing idea notes and see how this new idea relates to them. Does it confirm or contradict one? Write a sentence about that and make an internal link in Evernote to that other idea. Of course you can only do this when you have existing ideas, so the beginning will mostly be connecting. But your collection will grow and soon you'll have a network of ideas that relate to each other. That's why it's important not to just categorize notes/ideas with tags or notebooks, you want to actually fit them into your thinking. Does that make sense? The thing with Evernote is it probably takes quite a bit of work to do that, linking notes manually and everything. But it's still easier than what Luhmann did with his handwritten notes in a literal slip-box. New tools like Roam make it even easier though, links between notes are created automatically, allowing a much more intuitive and easy way of using the Zettelkasten method. Anyway, these are the very basics. If you're interested in the method, how to use it and the thoughts behind it, I recommend the book How to Take Smart Notes by Sönke Ahrens.

[@prc7084]

I tried to make the Zettlekastan template on Evernote. Topic:_______________ Literature notes: Short notes in bullet points format * ______ *_______ Reference /Master note: Whether the note is a Master note or a Reference note If Master note If Reference note Reference link/s: Reference link/s: * ______ * ______ *_______ *_______ Reference note/s: Master note/s: * ______ * ______ *_______ * ______ Similar Reference note/s: * ______ Permanent notes: Relating how the reference notes relate to each other while learning. Add new values to the existing ideas, arguments & discussions & finding the meaningful connections between what you just learned & what you already know Paste the merged reference notes here to add new ideas. These notes will be in the original format in their original place but here you need to highlight what extra information you are adding to each of the existing notes (by using font editing tools) Add the keywords based on these 2 questions- 1: In what circumstances do I want to stumble upon this note? 2: When & how will I use this idea?

[@ServantStatusMinistries]

Use Notion, Dynalist, or Roam research to help help you do this. Evernote doesn’t have a good interlinking system

Is a reference note like a comment on literature notes with reference to that literature note? or it's a note which has a reference to a book?

Yes that is a valid concern. I think you should export your notes from Roam as Markdown then probably you can import them to Evernote or OneNote? Or you can use Google Drive or Drop Box.
