Reframing and simplifying the idea of how to keep a Zettelkasten

Given many of the misconceptions I see online of how to keep a zettelkasten, particularly given the focus on the arcane addressing system used by Niklas Luhmann, perhaps it may be helpful to dramatically reframe the question of how to keep a zettelkasten? One page blog posts from people who’ve only recently seen the idea and are synopsizing it without a year or more practice themselves are highly confusing at best. Can I write something we don’t see enough of in spaces relating to zettelkasten? Perhaps we should briefly consider the intellectual predecessor of the slip box?

(Editor’s note: I’m using content within my own “slip box” to write this.)

Start out by forgetting zettelkasten exist. Instead read about what a commonplace book is and how that (simpler) form of note taking works. This short article outlined as a class assignment is a fascinating way to start and has some illustrative examples: https://www.academia.edu/35101285/Creating_a_Commonplace_Book_CPB_. If you’re a writer, researcher, or journalist, perhaps Steven Johnson’s perspective may be interesting to you instead: https://stevenberlinjohnson.com/the-glass-box-and-the-commonplace-book-639b16c4f3bb

The general idea is to collect interesting passages, quotes, and ideas as you read. Keep them in a notebook and call it your commonplace book. If you like call these your “fleeting notes” as some do.

As you do this, start building an index of subject headings for your ideas, perhaps using John Locke’s method (see this for some history and a synopsis: https://publicdomainreview.org/collection/john-lockes-method-for-common-place-books-1685).

Once you’ve got this, you’ve really mastered the majority of what a zettelkasten is and have a powerful tool at your disposal. If you feel it’s useful to you, you can add a few more tools and variations to your set up.

Next instead of keeping the ideas in a notebook, put them on index cards so that they’re easier to sort through, move around, and re-arrange. This particularly useful if you want to use them to create an outline of your ideas for writing something with them. Once you’ve got index cards (slips) with ideas on them in a box, you now literally meet the minimum requirements of a zettelkasten (German for “slip box”, though in practice many will have their ideas in a metaphorical slip box using a digital note taking tool.

Next, maybe keep some index cards that have the references and bibliographies from which your excerpting and note taking comes from. Link these bibliographical cards to the cards with your content.

As you go through your notes, ideas, and excerpts, maybe you want to further refine them? Write them out in your own words. Improve their clarity, so that when you go to re-use them, you can simply “excerpt” material you’ve already written for yourself and you’re not plagiarizing others. You can call these improved notes, as some do either “permanent notes” or “evergreen notes”.

Perhaps you’re looking for more creativity, serendipity, and organic surprise in your system? Next you can link individual notes together. In a paper system you can do this by following one note with another or writing addresses on each card and using that addressing system to link them, but in a digital environment you can link one note to many multiple others that are related. If you’re not sure where to start here, look back to your subject headings and pull out cards related to broad categories. Some things will obviously fit more closely than others, so be more selective and only link ideas that are more intimately connected than just the subject heading you’ve used.

Now when you want to write or create something new on a particular topic, ask your slip box a question and attempt to answer it by consulting your index. Find cards related to the topic, pull out those and place them in a useful order to create an outline perhaps using the cross links that already exist. (You’ve done that linking work as you went, so why not use it to make things easier now?) Copy the contents into a document and begin editing.

Beyond the first few steps, you’re really just creating additional complexity to a system to increase the combinatorial complexity of juxtaposed ideas that you could potentially pull back out of your system for writing more interesting text and generating new ideas. Some people may neither want nor need this sort of complexity in their working lives. If you don’t need it, then just keep a simple commonplace book (or commonplace card file) to remind you of the interesting ideas and inspirations you’ve seen and could potentially reuse throughout your life.

The benefit of this method is that beyond creating your index, you’ll always have something useful even if you abandon things later on and quit refining it. If you do go all the way, concentrate on writing out just two short solid ideas every day (Luhmann averaged about 6 per day and Roland Barthes averaged 1 and change). Do it until you have between 500 and 1000 cards (based on some surveys and anecdotal evidence), and you should begin seeing some serendipitous and intriguing results as you use your system for your writing.

We should acknowledge that that (visual) artists and musicians might also keep commonplaces and zettelkasten. As an example, Eminem keeps a zettelkasten, though he calls his “stacking ammo”, but it is so minimal that it is literally just a box and slips of paper with no apparent organization beyond this. If this fits your style and you don’t get any value out of having cards with locators like 3a4b/65m1, then don’t do that (for you) useless make-work. Make sure your system is working for you and you’re not working for your system.

Sadly, it’s generally difficult to find a single blog post that can accurately define what a zettelkasten is, how it’s structured, how it works, and why one would want one much less what one should expect from it. Sönke Ahrens does a reasonably good job, but his explanation is an entire book. Hopefully this distillation will get you moving in a positive direction for having a useful daily practice, but without an excessive amount of work and perhaps a bit less cognitive dissonance. Once you’ve been at it a while, then start looking at Ahrens and others to refine things for your personal preferences and creative needs.

Differentiating online variations of the Commonplace Book: Digital Gardens, Wikis, Zettlekasten, Waste Books, Florilegia, and Second Brains

A fluorescence of note taking tools

Over the past three or so years there has been a fluorescence of digital note taking tools and platforms.

Some of these include:

Open source projects like Org Mode, Logseq, Foam, Jupyter, Trilium, Databyss, Athens, Dendron, Anagora, and Hypothes.is.

Closed sourced projects like: Roam Research, Notion, Knovigator, Amplenote, RemNote, Memex, Nototo, nvUltra, and Are.na.

Some are based on earlier incarnations of note taking and writing tools like OneNote, Evernote, Simple Note, TiddlyWiki, DEVONthink, Scrivener, etc.

This brief list doesn’t take into account a sea of other mobile apps and platforms in addition to a broad array of social media platforms that people use for similar note taking or annotations.

My particular interest in some of this note taking field comes in the growing number of people who are working in public and sharing their notes in online settings with others. This has been happening organically since the rise of the internet and has happened on blogs within the blogosphere and on personal and communal wikis.

As was highlighted (pun intended) at the recent I Annotate 2021 conference, the note taking space seems to have been coming to a new boil. With the expansion of the ideas of keeping a zettelkasten or a digital garden, these versions of notebooks seem to be a significant part of this new note taking craze.

One thing I have noticed, however, is a dramatic lack of continuity in the history of note taking within the longue durée of Western civilization. (Other cultures including oral cultures have similar traditions, but for our purposes here, I won’t go into them except to say that they’re highly valuable, spectacularly rich, and something of which we should all be aware.)

Many of these products are selling themselves based on ideas or philosophies which sound and even feel solid, but they’re completely ignoring their predecessors to the tune of feeling like they’re trying to reinvent the wheel. As a result, some of the pitches for these products sound like they’re selling snake oil rather than tried and true methods that go back over 2,000 years of intellectual history. I can only presume that modern education is failing us all dramatically. People are “taught” (maybe told is the better verb) to take notes in school, but they’re never told why, what to do with them, or how to leverage them for maximum efficiency. Perhaps the idea has been so heavily imbued into our culture we’ve honestly forgotten the basic parts and reasoning behind it?

Even Vannevar Bush’s dream of the Memex as stated in his article As We May Think (The Atlantic, 1945), which many of these note taking applications might point to as an inspiration, ignores this same tradition and background, so perhaps these app creators and users aren’t all to blame?

Delineating Online Forms

I’ve been doing some serious reading and research into these traditions to help uncover our missing shared history. I’ll write something longer and more specific about them at a later date.

In the meanwhile, I want to outline just a bit about the various flavors as they relate to some of the more public online versions that I see in the related internet spaces. I hope to help better delineate what they have in common, how they differ, and what they may still add to the mix to get us to a more robust version of Bush’s dream.

Other’s thoughts and comments about these various incarnations and their forms and functions are both encouraged and appreciated.

Commonplace books

Historically commonplace books are one of the oldest and most influential structures in the note taking, writing, and thinking space. They have generally been physical books written by hand that contain notes which are categorized by headings (or in a modern context categories or tags. Often they’re created with an index to help their creators find and organize their notes.

They originated in ancient Greece and Rome out of the thought of Aristotle and Cicero as a tool for thinking and writing and have generally enjoyed a solid place in history since. A huge variety of commonplaces have been either copied by hand or published in print book form over the centuries.

Most significant thinkers, writers, and creators throughout history have kept something resembling a commonplace book. While many may want to attribute the output of historical figures like Erasmus, Newton, Darwin, Leibnitz, Locke, or Emerson to sheer genius (and many often do), I might suggest that their works were the result of sustained work of creating personal commonplace books—somewhat like a portable Google search engine for their day, but honed to their particular interests. (One naturally can’t ignore their other many privileges like wealth, education, and time to do this work, which were also certainly a significant factor in their success.)

Many people over the past quarter of a century have used a variety of digital forms to keep digital commonplace books including public versions on blogs, wikis, and other software for either public or private consumption.

Florilegium

Florilegia are a subcategory of commonplace book starting around 900 CE but flourishing in the 12th and 13th centuries and primarily kept by theologians and preachers. The first were a series of short excerpted passages often arranged in order of their appearance in a single text, but eventually were arranged systematically under discrete headings. Medieval florilegia where overwhelmingly, and often exclusively, concerned with religious topics from the works of scriptures, the moral dicta of the Doctors of the Church, and—less frequently—the teachings of approved, classical moral philosophers. The idea and form of florilegium generally merged back into the idea of the commonplace book which had renewed interest and wide popularity during the Renaissance.

These didn’t add any new or innovative features over what had come before. Perhaps, if anything, they were a regression because they so heavily focused only on religion as a topic.

Few (if any) examples of florilegia can be found in modern digital contexts. Though I have seen some people talk about using digital note taking tools for religious study, I have yet to see public versions online.

Zettelkästen

Born out of the commonplace tradition with modifications by Conrad Gessner (1516-1565) and descriptions by Johann Jacob Moser (1701–1785), the Zettelkasten, a German word translated as “slip box”, is generally a collection of highly curated atomic notes collected on slips of paper or index cards. Zettelkasten were made simpler to create and maintain with the introduction of the mass manufacture of index cards (and card boxes and furniture) in the early 20th century. Slips of paper which were moveable within books or files and later on index cards were a significant innovation in terms of storing and organizing a commonplace book.

Generally zettels (or cards) are organized by topics and often contain dates and other taxonomies or serialized numbers as a means of linking them to other cards within the system. The cross linking of these cards (and thus ideas) were certainly a historical physical precursor of the internet we have today, simply in digital form.

Almost all the current references I’ve seen online to Zettelkasten mention Niklas Luhmann as their inspiration, but none of them reference any other well-known historical examples despite the fact the idea has been around and evolving for several centuries now.

This productivity system and sets of digital tools around it came to greater attention in Germany in 2013 with the exhibition “Zettelkästen: Machines of Fantasy” at the Museum of Modern Literature, Marbach am Neckar and in 2014 with the launch of the zettelkasten.de website. A subsequent boost in the English speaking world occurred following the publication of Sönke Ahrens’s book How to Take Smart Notes – One Simple Technique to Boost Writing, Learning and Thinking – for Students, Academics and Nonfiction Book Writers in February 2017. The recent ability to use platforms like Roam Research, Obsidian, Notion, et al. has helped to fan the flames of their popularization.

More often than not, most of these digital tools (like their card-based predecessors) are geared toward private personal use rather than an open public model. Roam Research and Obsidian Publish have features which allow public publishing. TiddlyWiki is also an excellent tool for this as its so-called Tiddlers have a card-based appearance and can be placed in custom orders as well as transcluded, but again not many are available to the online public.

Waste books/Sudelbücher

This sub-genre of notebooks comes out of the tradition of double-entry book keeping where accountants often kept a daily diary of all transactions in chronological order. These temporary notes were then later moved into a more permanent accounting ledger and the remaining book was considered “waste”.

In the commonplace book tradition, these books for temporary notes or (fleeting notes in a Zettelkasten framing), might eventually be copied over, expanded, and indexed into one’s permanent commonplace collection.

In modern digital settings, one might consider some of the ephemeral social media stream platforms like Twitter to be a digital version of a waste book, though to my knowledge I may be the first person to suggest this connection. (To be clear, others have certainly mentioned Twitter as being a waste and even a wasteland.)

Wikis

Inspired, in part, by Apple’s HyperCard, Ward Cunningham created the first public wiki on his website on March 25, 1995. Apple had designed a system allowing users to create virtual “card stacks” supporting links among the various cards (sound familiar?). HyperCard was designed as a single user system.

Wikis allowed multiple users to author and edit pages on the web with a basic web browser. They were also able to create meaningful links and associations between pages, whether they existed or not using [[WikiLinks]]. They were meant to allow the average visitor to participate in an ongoing process of creation and collaboration.

Here there is some innovative user interface as well as the ability to collaborate with others in keeping a commonplace book. Transclusion of one page into another is a useful feature here.

Personal wikis have been used (as have many blogs) for information aggregation and dissemination over the years in a manner similar to their historical predecessors.

Second brain

Second brain is a marketing term which stands in for the idea of the original commonplace book. It popped up in the note taking context in early 2017 for promoting the use of commonplace books techniques using Tiago Forte’s expensive online course Building a Second Brain which focused on capturing, organizing, and sharing your knowledge using (digital) notes. It is a platform agnostic method for improving productivity wholly using the commonplace underpinning.

Google searches for this term will be heavily mixed in with results about the gastrointestinal system being the body’s “second brain”, the enteric nervous system, second brain tumors, a debunked theory that dinosaurs had two brains, and other general health-related topics.

Some websites, personal wikis and other online versions will use the phrase second brain, but they generally have no innovative features that are missing from prior efforts. Again, I view the phrase simply as marketing with no additional substance.

Digital Gardens

Informed heavily by their cultural predecessors in commonplace books, zettelkasten, and wikis, digital gardens are digital first note collections which are primarily public by default and encourage the idea of working in public.

Digital Gardens arose more formally in 2019 and 2020 out of the work and influence of Mark Bernstein’s 1998 essay Hypertext Gardens: Delightful Vistas, Ward Cunningham’s Smallest Federated Wiki (which just celebrated it’s 10th anniversary), Mike Caulfield’s essays including The Garden and the Stream: A Technopastoral as well as some influence from the broader IndieWeb Community and their focus on design and user interface.

Digital garden design can often use the gardening metaphor to focus attention on an active tending and care of one’s personal knowledge base and building toward new knowledge or creations. The idea of planting a knowledge “seed” (a note), tending it gradually over time with regular watering and feeding in a progression of 🌱 Seedlings → 🌿 Budding → 🌳 Evergreen is a common feature.

There are a growing number of people with personal digital gardens in public. Many are built on pre-existing wiki software like WikiMedia, the Smallest Federated Wiki, or TiddlyWiki, static site generators like Jekyll, note taking platforms like Obsidian Publish and Roam Research, or even out of common blogging software like WordPress. A growing common feature of these platforms is that they not only link out to resources on the open web, but contain bidirectional links within themselves using either custom code (in a wiki-like manner) or using the W3C Webmention specification.

The Future?

With luck, application and platform designers and users will come to know more about the traditions, uses, and workflows of our rich cultural note taking history. Beyond this there are a few innovations, particularly in the public-facing arena which could be useful, but which aren’t broadly seen or available yet.

Still missing from the overall personal knowledge and note taking space is a more tightly integrated version of both a garden and a stream (in Mike Caulfield’s excellent framing) that easily allows interaction between the two arenas. Some of the more blog-based sites with notes, bookmarks, articles and IndieWeb friendly building blocks like Webmention, feeds (RSS, JSON Feed, h-feed), Micropub, and Microsub integrations may come the closest to this ideal.

One of the most fascinating recent entrants on the scene is Flancian’s Anagora which he uses as a personal commonplace book in a wiki-esque style. Over other incarnations it also has the ability to pull in and aggregate the notes of other digital commonplace books to create a larger marketplace of ideas. It also includes collaborative note taking space using Etherpad, which I’ve seen as a standalone tool, but never integrated into a digital commonplace book.

Ultimately, my dream—similar to that of Bush’s—is for individual commonplace books to be able to communicate not only with their users in the Luhmann-esqe sense, but also communicate with each other.

Niklas Luhmann apparently said:

Ohne zu schreiben, kann man nicht denken; jedenfalls nicht in anspruchsvoller, anschlussfähiger Weise.

(Translation) You cannot think without writing; at least not in a sophisticated, connectable way.

I think his conceptualization of “connectable” was much more limited and limiting than he might have guessed. Vannevar Bush, as the academic advisor of Claude Shannon, the godfather of the modern digital age, was more prepared to envision it.

(Luhmann’s “you” in his quote is obviously only a Western cultural referent which erases the existence of oral based cultures which have other ways to do their sophisticated thinking. His ignorant framing on the topic shouldn’t be a shared one.)


This post has grown out of my own personal commonplace book, portions of which are on housed on my blog, in a wiki, and in a private repository of which I hope to make more public soon. Further thoughts, ideas and expansions of it are more than welcome.

I’ve slowly been updating pieces of the history along with examples on shared commonplaces in both the IndieWeb Wiki and Wikipedia under the appropriate headings. Feel free to browse those or contribute to them as you would, at least until our digital commonplace books can communicate with each other.

I’d also invite those who are interested in this topic and who have or want online spaces to do this sort of thing to join us at the proposed upcoming Gardens and Streams II IndieWebCamp Pop up session which is being planned for later this Summer or early Fall. Comment below, stop by the page or chat to indicate your interest in attending.

Watched “Shetland” Red Bones: Part 2 from BritBox
Directed by Peter Hoar. With Gemma Chan, Steven Robertson, Douglas Henshall, Alison O'Donnell. With two murders and no strong leads, can Perez apprehend the suspect before crowds descend on the Shetland Islands for Up Helly Aa, the biggest fire festival in Europe?
The Up Helly Aa could have been used to up the stress and tension even more than it did here.

While a good pair of episodes, I think I definitely liked the book better , especially for building character.

Watched “Shetland” Red Bones: Part 1 from BritBox
"Shetland" Red Bones: Part 1 Directed by Peter Hoar. With Sandra Voe, Douglas Henshall, Erin Armstrong, Steven Robertson. As DI Jimmy Perez investigates the murder of an elderly lady who is shot dead outside her croft, he finds evidence of a massive, bitter dispute between two families.
Finally circling back to watch some of the earlier episodes that I either missed or only caught portions of on PBS airings.

Subscribed to BritBox just for this (and its new season) and a few other things in the coming weeks.

As a botanist, Robin Wall Kimmerer as been trained to ask questions of nature with the tools of science. As a member of the Citizen Potawatomi Nation, she embraces the notion that plants and animals are our oldest teachers. In Braiding Sweetgrass, Kimmerer brings these lenses of knowledge together to show that the awakening of a wider ecological consciousness requires the acknowledgment and celebration of our reciprocal relationship with the rest of the living world. For only when we can hear the languages of other beings are we capable of understanding the generosity of the earth, and learning to give our own gifts in return.

IndieWeb Inspirational Cards

I’ve been tinkering with and test driving some various image creation tools.  To test them and simultaneously have some fun, I made a series of creative inspirational cards/inspirational posters/postcards for the IndieWeb. All the images are royalty free from Pixabay, and I’m releasing the text and additional work with a CC0 license. Feel free to download and use them to your hearts’ content. They should hopefully all be relatively well-sided for sharing on social media.

I’d love to hear folks’ thoughts about them in general.

Breaking news reporting often gets essential facts wrong. In fact, the rampant misreporting can be so common as to be predictable. And so, On the Media has developed formulas (with the help of experts) for how to spot spotty coverage. Rather than counting on news outlets to get it right, we're looking at the other end. We have some tips for how to sort good information from bad -- whether the breaking news is about a tragic mass shooting or a stock market crash, an epidemic or a rash of election polls. Below is our collection of Breaking News Consumer's Handbooks, and it's growing all the time. Each one comes with a printable PDF that you can tape to your wall the next time you encounter a big news event.
I’ve listened to many in this series over time, but there are a few I’ve missed and would like to revisit. 
Read George F Kennan by Gideon Rachman (ft.com)
John Lewis Gaddis’ biography of the US diplomat works brilliantly as a piece of intellectual history
George Kennan is a rare example of a diplomat who changed history through the power of his ideas and the clarity of his writing. In February 1946, Kennan, the number two at the US embassy in Moscow, sent a “long telegram” to his superiors in Washington DC. At a time when many Americans still regarded the Soviet Union as an ally, Kennan explained, in limpid prose, why there could never be a normal peacetime relationship with the USSR.
This looks like an interesting read.
