Casey Newton makes this blanket statement. Any real evidence for this beyond his "gut"?

Many "paper machines" like Niklas Luhmann's zettelkasten were almost custom made not just for searching, but for browsing through regularly much like commonplace books.

Perhaps the question is really, how is your particular database designed?

I had this problem too, but eventually switched to keeping my commonplace entirely on index cards, which also allows me to move them around and re-arrange them as necessary or when useful. (It also fixed some of my indexing problems.)

The side benefit is that if I botch a single card, no sweat, just pull out a new one and start over! If you like the higher end stationery scene afforded in notebooks, then take a look at Clairfontaine's bristol cards from Exacompta which are lush and come in a variety of sizes, colors, and rulings. (They're roughly equivalent to the cost per square meter of paper you'll find in finer notebooks like Leuchtturm, Hobonichi, Moleskine, etc., though some of the less expensive index cards still do well with many writing instruments.) Most of their card sizes are just about perfect for capturing the sorts of entries that one might wish to commonplace.

Once you've been at it a while, if you want to keep up with the luxe route that some notebook practices allow, then find yourself a classy looking box to store them all in to make your neighbors jealous. My card indexes bring me more joy than any notebook ever did.

When penmanship becomes a problem, then you can fix it by printing your cards, or (even better in my opinion), typing them on your vintage Smith-Corona Clipper.

And of course the first thing one could type out on their first card and file it at the front where you can see it every day:

"Le mieux est le mortel ennemi du bien" (The better is the mortal enemy of the good).<br /> — Montesquieu, in Pensées, 1726

aka "Don't let perfection be the enemy of the good."

Megan Rhiannon shows how she's using her FiloFax for planning as well as commonplacing.

u/practicalSloth interested in implementing a commonplace book using a FiloFax!

reply to u/practicalSloth at https://www.reddit.com/r/commonplacebook/comments/17drtzn/anyone_use_a_filofax_or_similar_for_a_commonplace/

For centuries, many have kept their commonplace books on index cards or slips of paper) rather than on book/notebook pages just like you're suggesting. They then indexed them against topic words and filed the ideas alphabetically rather than writing them in books and indexing them separately.

Some popular versions of the practice which are described/viewable online include:

• Ryan Holiday: https://ryanholiday.net/the-notecard-system-the-key-for-remembering-organizing-and-using-everything-you-read/ and https://thoughtcatalog.com/ryan-holiday/2013/08/how-and-why-to-keep-a-commonplace-book/ Ryan has also covered some of his methods on his YouTube channel as well.
• Billy Oppenheimer: https://billyoppenheimer.com/notecard-system/
• Victor Margolin: https://www.youtube.com/watch?v=Kxyy0THLfuI
• Mortimer J. Adler et. al.: https://boffosocko.com/2023/09/28/mortimer-j-adlers-syntopicon-a-topically-arranged-collaborative-slipbox/

Others with index card or small slip-based commonplaces include Ronald Reagan, Phyllis Diller (whose commonplaced joke file is now at the Smithsonian), and Joan Rivers.

In German, this general practice was called zettelkasten (which translates as slip box), there are lots of people doing versions of this in r/Zettelkasten following some of Niklas Luhmann's method. Many more are using digital platforms like Obsidian, Logseq, etc. for this.

Certainly putting it into a FiloFax is a flexible and doable option.

I've written a bit about the mistaken identities and differences between Niklas Luhmann's practice which has become popular in English speaking countries over the last decade and index card-based commonplaces: https://boffosocko.com/2022/10/22/the-two-definitions-of-zettelkasten/.

Perhaps some of the examples will give you some ideas for how to best do your own. Good luck!

Eric Hoffer apparently had a collection of quotes which he kept on index cards in boxes.

reply to u/ihaveascone at https://www.reddit.com/r/Zettelkasten/comments/14v2ohz/converting_commonplace_books/

Don't convert unless you absolutely need to, it will be a lot of soul-crushing make work. Since some of your practice already looks like Ross Ashby's system, why not just continue what you've been doing all along and start a physical index card-based index for your commonplaces? (As opposed to a more classical Lockian index.) As you browse your commonplaces create index cards for topics you find and write down the associated book/page numbers. Over time you'll more quickly make your commonplace books more valuable while still continuing on as you always have without skipping much a beat or attempting to convert over your entire system. Alternately you could do a paper notebook with a digital index too. I came across https://www.indxd.ink, a digital, web-based index tool for your analog notebooks. Ostensibly allows one to digitally index their paper notebooks (page numbers optional). It emails you weekly text updates, so you've got a back up of your data if the site/service disappears. This could potentially be used by those who have analog commonplace/zettelkasten practices, but want the digital search and some back up of their system.

reply to Bob Doto at https://www.reddit.com/r/Zettelkasten/comments/14lcb4z/using_diaries_and_journals_as_source_material_for/

Ross Ashby kept his notes in notebooks/journals but he did cross-index them by topic using index cards. Rather than reference them by notebook (name/title/date) and page number, he kept a set of handwritten running page numbers across the entirety of his notebooks, so instead of Notebook 15 page 55, 1952 he'd simply write "3786" for page 3786. This can be seen on his index card for the indexed word "determinate" as an example.

For other examples, see: http://www.rossashby.info/journal/index/index.html

My own notebooks are usually titled by year and date spans along with page numbers, so I'll use those roughly as Bob describes. This has made it much easier to not need to move all my older notes into a card-based system, but still make them useable and referenceable.

For those with more explicit journaling, diary, or other writing habits, Ralph Waldo Emmerson makes an interesting example of practice as he maintained at least two commonplace books (a poetry-specific one and a general one) as well as a large set of writing journals where he experimented with writing before later publishing his work. Since there are extant (digitized and published copies) and large bodies of scholarship around them, they make an interesting case study of how his process worked and how others might imitate it.

​

On the diary front, of the historical examples I've seen floating around, only Roland Barthes had a significant practice of keeping his "diary" in index card form, a portion of which was published on October 12, 2010. Mourning Diary is a collection published for the first time from Roland Barthes' 330 index cards focusing on his mourning following the death of his mother in 1977.

Not as extensive, Vladimir Nabokov recorded a "diary" of sixty-four dreams on 118 index cards beginning on October 14, 1964 as an experiment. He was following the instructions of John Dunne, a British philosopher, in An Experiment with Time. The results were published by Princeton University Press in Insomniac Dreams: Experiments with Time by Vladimir Nabokov which was edited by Gennady Barabtarlo.

Presumably if one keeps a diary or journal in index card form in chronological order, they can simply reference it by date and either time or card X of Y, if there are multiple card entries for a single day. I keep a dated diary of sorts on index cards, though they rarely go past one card a day.

u/zleonska in discussing their paper notebook commonplace practice reports that finding their material within multiple notebooks isn't difficult but that, like W. Ross Ashby, they use index cards to index their commonplaces.

Eugenia Triantafyllou is talking about crutches for creativity and inspiration, but seems to miss the value of collecting interesting tidbits along the road of life that one can use later. Instead, the emphasis here becomes one of relying on an artificial intelligence doing it for you at the "hit of a button". If this is the case, then why not just let the artificial intelligence do all the work for you?

This is the area where the cultural loss of mnemonics used in orality or even the simple commonplace book will make us easier prey for (over-)reliance on technology.

Is serendipity really serendipity if it's programmed for you?

As humans we're good at separating things based on categories. The Dewey Decimal System systematically separates mathematics and history into disparate locations, but your zettelkasten shouldn't force this by overthinking categories. Perhaps the overlap of math and history is exactly the interdisciplinary topic you're working toward? If this is the case, just put cards into the slip box closest to their nearest related intellectual neighbor—and by this I mean nearest related to you, not to Melvil Dewey or anyone else. Over time, through growth and branching, ideas will fill in the interstitial spaces and neighboring ideas will slowly percolate and intermix. Your interests will slowly emerge into various bunches of cards in your box. Things you may have thought were important can separate away and end up on sparse branches while other areas flourish.

If you make the (false) choice to separate math and history into different "sections" it will be much harder for them to grow and intertwine in an organic and truly disciplinary way. Universities have done this sort of separation for hundreds of years and as a result, their engineering faculty can be buildings or even entire campuses away from their medical faculty who now want to work together in new interdisciplinary ways. This creates a physical barrier to more efficient and productive innovation and creativity. It's your zettelkasten, so put those ideas right next to each other from the start so they can do the work of serendipity and surprise for you. Do not artificially separate your favorite ideas. Let them mix and mingle and see what comes out of them.

If you feel the need to categorize and separate them in such a surgical fashion, then let your index be the place where this happens. This is what indices are for! Put the locations into the index to create the semantic separation. Math related material gets indexed under "M" and history under "H". Now those ideas can be mixed up in your box, but they're still findable. DO NOT USE OR CONSIDER YOUR NUMBERS AS TOPICAL HEADINGS!!! Don't make the fatal mistake of thinking this. The numbers are just that, numbers. They are there solely for you to be able to easily find the geographic location of individual cards quickly or perhaps recreate an order if you remove and mix a bunch for fun or (heaven forfend) accidentally tip your box out onto the floor. Each part has of the system has its job: the numbers allow you to find things where you expect them to be and the index does the work of tracking and separating topics if you need that.

The broader zettelkasten, tools for thought, and creativity community does a terrible job of explaining the "why" portion of what is going on here with respect to Luhmann's set up. Your zettelkasten is a crucible of ideas placed in juxtaposition with each other. Traversing through them and allowing them to collide in interesting and random ways is part of what will create a pre-programmed serendipity, surprise, and combinatorial creativity for your ideas. They help you to become more fruitful, inventive, and creative.

Broadly the same thing is happening with respect to the structure of commonplace books. There one needs to do more work of randomly reading through and revisiting portions to cause the work or serendipity and admixture, but the end results are roughly the same. With the zettelkasten, it's a bit easier for your favorite ideas to accumulate into one place (or neighborhood) for easier growth because you can move them around and juxtapose them as you add them rather than traversing from page 57 in one notebook to page 532 in another.

If you use your numbers as topical or category headings you'll artificially create dreadful neighborhoods for your ideas to live in. You want a diversity of ideas mixing together to create new ideas. To get a sense of this visually, play the game Parable of the Polygons in which one categorizes and separates (or doesn't) triangles and squares. The game created by Vi Hart and Nicky Case based on the research of Thomas Schelling provides a solid example of the sort of statistical mechanics going on with ideas in your zettelkasten when they're categorized rigidly. If you rigidly categorize ideas and separate them, you'll drastically minimize the chance of creating the sort of useful serendipity of intermixed and innovative ideas.

It's much harder to know what happens when you mix anthropology with complexity theory if they're in separate parts of your mental library, but if those are the things that get you going, then definitely put them right next to each other in your slip box. See what happens. If they're interesting and useful, they've got explicit numerical locators and are cross referenced in your index, so they're unlikely to get lost. Be experimental occasionally. Don't put that card on Henry David Thoreau in the section on writers, nature, or Concord, Massachusetts if those aren't interesting to you. Besides everyone has already done that. Instead put him next to your work on innovation and pencils because it's much easier to become a writer, philosopher, and intellectual when your family's successful pencil manufacturing business can pay for you to attend Harvard and your house is always full of writing instruments from a young age. Now you've got something interesting and creative. (And if you must, you can always link the card numerically to the other transcendentalists across the way.)

In case they didn't hear it in the back, I'll shout it again: ACTIVELY WORK AGAINST YOUR NATURAL URGE TO USE YOUR ZETTELKASTEN NUMBERS AS TOPICAL HEADINGS!!!

Arthur introduces the topic of Robert Pirsig and slips into the GTD conversation on 2004-05-19.

Was this a precursor link to the Pile of Index Cards in 2006?

Note that there doesn't seem to be any discussion of any of the methods with respect to direct knowledge management until the very end in which arthur returns almost four months later to describe a 4 x 6" card index with various topics he's using for filing away his knowledge on cards. He's essentially recreated the index card based commonplace book suggested by Robert Pirsig in Lila.

A digitized web-based version of S.D. Goitein's commonplace book using index cards.

Wowzers!

Cards from the topically arranged index cards in Goitein's sub-collection of 20,000 served as the skeleton of his magnum opus Mediterranean Society.

Goitein, “Involvement in Geniza Research,” 144.

Goitein's cards are segmented into two sets: one for subjects and one related to the India Book.

via u/The_Bee_Sneeze

Example of someone using Obsidian with a zettelkasten focus to write screenplays.

Thought the example appears in r/Zettelkasten, one must wonder at how Luhmann-esque such a practice really appears?

Goitein accumulated more than 27,000 index cards in his research work over the span of 35 years. (Approximately 2.1 cards per day.)

His collection can broadly be broken up into two broad categories: 1. Approximately 20,000 cards are notes covering individual topics generally making of the form of a commonplace book using index cards rather than books or notebooks. 2. Over 7,000 cards which contain descriptions of a single fragment from the Cairo Geniza.

A large number of cards in the commonplace book section were used in the production of his magnum opus, a six volume series about aspects of Jewish life in the Middle Ages, which were published as A Mediterranean Society: The Jewish communities of the Arab World as Portrayed in the Documents of the Cairo Geniza (1967–1993).

Robert Greene's method goes back to junior high school when he was practicing something similar. He doesn't say he invented it, and it may be likely that teachers modeled some of the system for him. He revised the system over time to make it work for himself.

While the ancients thought of the commonplace as a storehouse of value or a treasury, modern knowledge workers and content creators might analogize it to a factory where one stores up ideas in a warehouse space where they can be easily accessed, put into a production line where those ideas can be assembled, revised, proofread, and then package and distributed to consumers (readers).

(summary)

Note that he explicitly calls out that his is an adapted version of a preexisting thing--namely a system that was taught to Ryan Holiday who was taught by Robert Greene.

Presumably there is both some economic and street cred value for the author/influencer in claiming his precedents.

It's worth noting that he mentions other famous users, though only the smallest fraction of them with emphasis up front on his teachers whose audience he shares financially.

This is almost pitched as a product with the brand name "The Notecard System".

According to Keith Thomas, "many of the great 19th-century historians employed professional copyists" as a means of keeping up with filing copies of their note slips under multiple subject headings.

Index cards for commonplacing?

I know that Robert Greene and Ryan Holiday have talked about their commonplace methods using index cards before, and Mortimer J. Adler et al. used index cards with commonplacing methods in their Great Books/Syntopicon project, but is anyone else using this method? Where or from whom did you learn/hear about using index cards? What benefits do you feel you're getting over a journal or notebook-based method? Mortimer J.

Breitenbach, H. P. “The Card Index for Teachers.” The School Review 20, no. 4 (1912): 271–72.

Apparently in 1912, the card index was little known to teachers... this isn't the sort of use case I was expecting here...

The general gist of this short note is an encouraging one to suggest that instead of traditional grade books, which are still used heavily in 2022, teachers should use rolodex like cards for keeping attendance and notes on a student's progress.

Presumably this never caught on. While some elementary teachers still use older paper gradebooks, many others have transferred to digital LMS platforms.

As many people used slip boxes in 1930s Germany, publishers sold texts, not as typical books, but as file card collections!

By at least 2013 Ryan Holiday was aware of Ronald Reagan's note card system from a 2011 USA Today article and related book.

flashcards?!?!! A commonplace book done in index cards is NOT based on "flashcards". 🤮

Someone here is missing the point...

u/sscheper in writing your book, have you thought about the following alternative publishing idea which I'm transcribing from a random though I put on a card this morning?

I find myself thinking about people publishing books in index card/zettelkasten formats. Perhaps Scott Scheper could do this with his antinet book presented in a traditional linear format, but done in index cards with his numbers, links, etc. as well as his actual cards for his index at the end so that readers could also see the power of the system by holding it in their hands and playing with it?

It could be done roughly like Edward Powys Mathers' Cain's Jawbone or Henry Korn's Pontoon Manifesto? Perhaps numbered consecutively to make it easier to bring back into that format, but also done with your zk numbering so that people could order it and use it that way too? This way you get the book as well as a meta artifact of what the book is about as an example of how to do such a thing for yourself. Maybe even make a contest for a better ordering for the book than the one you published it in ?

In an interview with Le Monde in 1973, Barthes indicated that while his note taking practice was somewhat akin to that of a commonplace book where one might collect interesting passages, or quotations, he was also specifically writing down ideas which came to him, but doing so in "in the rhythm of a sentence, so that from that moment on, things are already taking on an existence as writing." This indicates that he's already preparing for future publications in which he might use those very ideas and putting them into a more finished form than most might think of when considering shorter fleeting notes used simply as a reminder. By having the work already done, he can easily put his own ideas directly into longer works.

Was there any evidence that his notes were crosslinked or indexed in a way so that he could more rapidly rearrange his ideas and pre-written thoughts to more easily copy them into longer articles or books?
