I posed your question to my own card index:

Generally scientists haven't spent the time to talk about their methods the way those in the social sciences and humanities are apt to do. This being said, their methods are unsurprisingly all the same.

If you want to look up examples, you can delve into the nachlass (digitized or not) of most of the famous scientists and mathematicians out there to verify this. Ramon Llull certainly wrote, but broadly memorized all of his work; Newton had his wastebooks; Leibnitz used Thomas Harrison's Ark of Studies cabinet; Carl Linnaeus "invented" index cards for his work (search for the work of Staffan Müller-Wille and Isabelle Charmantier); Erasmus Darwin and Charles Darwin both used commonplace books; physicist Mario Bunge had a significant zettelkasten practice; Richard Feynman used notebooks; engineer Ross Ashby used a combination of notebooks which he indexed using a card index.

For historical reasons, most used a commonplace book method in which they indexed against keywords rather than Luhmann's variation, but broadly the results are the same either way.

Computer scientist Gerald Weinberg is one of the few I'm aware of within the sciences who's written a note taking manual, but again, his method is broadly the same as that described by other writers for centuries:

Weinberg, Gerald M. Weinberg on Writing: The Fieldstone Method. New York, N.Y: Dorset House, 2005.

I identify as both a mathematician and an engineer, and I have a paper-based zettelkasten for these areas, primarily as I prefer writing out equations versus attempting to write everything out as LaTeX. I'm sure others here could add their experiences as well. I've previously written about zettelkasten from the framing of set theory, topology, dense sets, and have even touched on it with respect to the ideas of equivalence classes and category theory, though I haven't published much in depth here as most don't have the mathematical sophistication to appreciate the structures and analogies.

Edward Lane's Arabic English Lexicon sounds like it was compiled by means of card index. Worth looking into the scholarly method behind compiling it.

Researcher Michael Macdonald created a card index database of safaitic inscriptions which he and French archaeologist Laïla Nehmé eventually morphed into a digital database which included a collection of photographs of the extant texts.

Fascinating that within a section or prose about indexing within MiddleMarch (set in 1829 to 1832 and published in 1871-1872), George Eliot compares a character's distinguished appearance to that of John Locke!

Mr. Brooke asks for advice about arranging notes as he has tried pigeon holes but has the common issue of multiple storage and can't remember under which letter he's filed his particular note. Mr. Casaubon indicates that he uses pigeon-holes.

Dorothea Brooke mentions that she knows how to properly index papers so that they might be searched for and found later. She is likely aware of John Locke's indexing method from 1685 (or in English in 1706) and in the same scene compares Mr. Casaubon's appearance to Locke.

While the idea of a common user interface on computers may have felt like a selling point when facing a new scary machine with a variety of functionalities, did it really save that much time, effort, and learning curve? Particularly with respect to the common office tools it was replacing?

The common user interface was really more a benefit to the company and all the companies which programmed for it at scale. The benefits are like Melvil Dewey's standardization of the Dewey Decimal Classification which allowed libraries everywhere to work on the same system rather than needing to reinvent their own individually.

This sort of innovation with scalability is helpful as humans are far better at imitation than innovation.

In 1983, at the dawn of the personal computer age, Apple Inc. in promotional film entitled "Lisa Soul Of A New Machine" touted their new computer, a 16-bit dual disk drive "personal office system", as something that would do away with "the cluttered desk, index cards, file folders, the in-out basket, [and] the calculator." (00:01)

Some of these things moved to the realm of the computer including the messy desk(top) now giving people two messy desks, a real one and a virtual one. The database-like structure of the card index also moved over, but the subjective index and its search power were substituted for a lower level concordance search.

30 years on, for most people, the value of the database idea behind the humble "index card" has long since disappeared and so it seems here as if it's "just" another piece of cluttery paper.

Appreciate the rosy framing of the juxtaposition of "past" and "future" jumping over the idea of the here and now which includes the thing they're selling, the Lisa computer. They're selling the idealized and unclear future even though it's really just today.

There's an interesting dichotomy presented here about the tech forwardness of the automobile industry in 1908 versus the tech reticence of the carriage builders in regard to adopting card indexes with respect to their related (though different) industries.

Me (sarcastically):<br /> "Oh, those backwards carriage builders will get with the 'program' any day now..."

Variations of card index systems were published in booklet form by filing cabinet manufacturers as a means of selling not only their cabinets, but their systems for using them was common in the early 1900s. Examples of magazine advertisements in System Magazine back this up. It is also specifically highlighted in a review of J. Kaiser's book "The Card System at the Office" from Ironmonger (1909-10-03) which appreciates a more fully fleshed out version of a card index system in book form without mention of specific manufacturing firms.

When were bookmark-like "flags" introduced in America? (Certainly prior to 1908, based on this reference.)

anecdotal evidence from Ironmonger (1908) that this is the first card index book and prior versions are only of shorter booklet-like forms.

(Naturally, I don't trust this in the fullest sense.)

Regular note taking practice will be the best indicator of when potential improvements are worthwhile. Though you may see someone else's advice, workflows, or potential improvements, they may be just as likely not to work for you and your particular needs. Adopting changes without thinking them through or even practicing them for a while are more likely to cause harm, regret, or additional work without any value added to the system.

The description here is almost similar to interdepartmental memos or corporate emails which are sent out now instead. This information flows out, but broadly isn't kept or filed in the same sorts of ways.

Key cabinets are used to control the information found in other card indexes as well as for private business information which should be restricted within a firm.

Business Ledger

This section looks at index cards for communication to/from clients and appropriate follow up with respect to sales management in a manufacturing firm. It broadly represents some examples of how one would do larger scale project management and follow up with index cards.

Broadly this sounds like an indexed corporate diary of sorts, but his use of future reminders (or ticklers in the footnote) certainly points to the use of index cards in a Memindex-like fashion.

Keep in mind that he's writing in Britain and the Memindex from 1903 was a US-based product, though similar ideas may have been used at the time across the pond.

examples of specific workflows within Kaiser's card system

https://www.ebay.com/itm/276403515343 <br /> archived copy

In 1984, Memindex was selling monthly planning calendars (pocket notebook size with spiral binding and a case) rather than their older small index card sized formats. Their calendar format looks eerily like what Day-Timer, a division of ACCO Brands, has been selling since at least the early 1990s.

This goes down to even the "cut here" triangles in the lower right corners of pages to help bookmark the current page.

Early 20th century mail merge using a card index!

This is a restatement that a particular system should be customized to its users.

There is potential that a system could be applied universally, but it requires a very large amount of data and metadata to suit the needs of a greater number of people and use cases. It also requires a reasonable amount of work in practical use to make it operate as expected.

The Mundaneum was likely close on paper and Google comes close to this, but still isn't perfect.

quote via ¶76 and 92

Devising Card Systems

Many modern-day note takers and knowledge workers might take solace in the broad advice provided by J. Kaiser in 1908. In describing some of the broad categories of uses of card index filing systems for business use he says that each entity "has its individual character and individual requirements, and its individual character" (ie, everyone is different and has different needs), therefore everyone "must devise [their] system in accordance with [their] own requirements" and should "be the best judge as to what these requirements are." He continues on in the rest of the book to outline a variety of suggestions and methods which one might use or adopt, but he doesn't dictate specific methods and leaves those decisions up to the end user.

When devising their own systems, one certainly ought to heed this advice when looking at a variety of alternative methods like Forte's P.A.R.A., Milo's LYT, or even in mimicking Luhmann's idiosyncratic Zettelkasten set up. Are these methods best for your particular use cases? Are they simple enough for what you want to do, or are they overly structured and complicated? The key is to be able to classify and file things quickly so that they can be easily accessed in the future, all the rest becomes additional details and overhead to support on an ongoing basis.

(¶76)

In describing classification schemes for card index-based business uses, Julius Kaiser indicated in 1908 that "elaborate library classifications were either inapplicable or much too complicated and therefore unmanageable." This is in part because of the standardization of the Dewey Decimal System, which may have provided efficiencies for library systems, but proved too rigid for the idiosyncrasies of a variety of businesses. Instead he describes an alpha-numeric system in which numbers provide simple means of finding while the initial alphabetic codes assign specific office-related classes (correspondence, press cuttings, catalogs, etc.) to the indexed materials.

grin

This sort of failure is still seen today with people setting up note taking systems in a variety of digital environments.

Setting up and learning a note taking or card index system has a reasonably large up-front cost, but learning it well and being able to rely on it over long periods of time will eventually reap larger and cheaper long-term outcomes and benefits.

Unless changing systems creates dramatically larger improvements, the cost of change will surely swamp the benefits making the switch useless. This advice given by Kaiser is still as true today as it was in 1908, we tend not to think about the efficiency as much now as he may have then however and fall trap to shiny object syndrome.

In modern, digital settings, the work of approapriately indexing content is lost in exchange for other forms of organization (tagging, for example), this means one is less reliant on an index for looking up material and more reliant on concordance search of particular words within an ever-growing corpus of collected knowledge.

Over time and with scale, simple tagging may become overwhelming as a search method for finding the requisite material, even when one knows it exists.

As a result a repository may do better in the long run with a small handful of carefully applied rules from the start.

This quote is broadly recognized in economic settings as true, but few in the knowledge management space place emphasis or focus on designing both simple systems which are easy to master and use on a regular, ongoing basis. This allows the knowledge worker the ability to more quickly (almost blindly) handle their indexing and filing operations so that things are precisely where they need them when required for use.

Poor design will not only decrease the ease of use, but also discourage the user from both efficiently using and benefiting from their systems.

Even simple and efficient filing systems require familiarity and expertise for them to effect useful gains to their users, and prove their effectiveness over time. If a user can't get to a basic level of functionality in short time, they're likely to give up on it and never see the ultimate benefits.

Julius Kaiser contemporaneously posits that mass manufacture and maximizing efficiency (greater output for minimum input) are the primary drivers of card index system use in the early 20th century. These also improve both precision and accuracy in handling information which allow for better company or factory operation, which would have been rising concerns for businesses and manufacturing operations at the rise of scientific management during the time period.

Given this date, he's potentially either giving advice to consumers about what to buy or manufacturers about how to design and improve their systems.

He notes the general equivalency of cards and papers in vertical files.

One of the primary affordances that individual atomic cards have is the ability to more easily re-arrange and reuse them for various purposes in comparison with larger sheets with greater amounts of data on them.

Index card quality can be important for cards that are repeatedly used.

This admonition was more frequently attended to with respect to library card catalogs, but potentially less followed in personal use—Niklas Luhmann's self-cut paper slips which wore ragged over time come quickly to mind here.

I've seen some mixed cabinet in the early 1900s, but apparently by 1908, it was common practice to separate vertical filing cabinets and card cabinets.

¶5

The book is ostensibly in the form of a card index with numbers laid out in running order to create a book. The index is also done keyed to these paragraph numbers rather than by page as has traditionally been done.

As a result, one could cut up the book (or two copies to get both sides) and turn it back into a card index with very little work.

companion volumes treated the topics of "analysing literature" and the application of tabulated cards to practical business "at the Factory".

In extolling the Ark of Studies created by Thomas Harrison, Samuel Hartlib indicated that the combinations of information and the potential links between them created the "argumentative part" of the system. In some sense this seems to be analogous to the the processing power of an information system if not specifically creating its consciousness.

definition: syndetic structure is one of coherency and resolution made up by referential links.

Why is no one using this word in the zettelkasten space?

The adjective "syndetic" means "serving to connect" or "to be connected by a conjunction". (A conjunction being a word used to connect words, phrases and clauses, for example: and, but, if). The antonym is "asyndetic" (connections made without conjoins)

Digitization efforts in card collections may result in the loss or damage of cards or loss of the materials which the original cards represented in the case of library card catalogs.

Libraries may have handwritten notes on the back of library card catalog cards in the 20th century, a practice which caused data loss in the case of the Alderman Library which only scanned the front of their cards in 1989 when they made the switch from physical cards to a digital catalog.

This is roughly 65 cabinets of 60 drawers each.

4 million cards over 50 years is approximately 220 cards per day. This isn't directly analogous to my general statistics on number of notes per day for individual people's excerpting practice, but it does give an interesting benchmark for a larger institution and their acquisitions over 50 years. (Be sure to divide by 3 for duplication over author/title/subject overlap, which would be closer to 73 per day)

The Grimmwelt Museum in Kassel, Germany is the home of some of the work of Grimm Brothers work on the Deutsches Wörterbuch which features a large wall of zettel or slips hanging from long nails.

The slips hanging on nails sounds similar to Thomas Harrison's 1740's wooden cabinet of hanging slips used for excerpts and isn't far off from the organizational structure used by the subsequent Oxford English Dictionary's pigeonhole system of organization for their slip collection.

Some of King's note cards later figured in his speeches including his "I Have a Dream" speech.

each sub-portion has its own topology. The index is decentralized in nature, while the bibliographical section/notes are all somewhat centralized in form.

I imagine this diversity of structure is what made Luhmann's slipbox so potent. In an ecosystem, neither an arboreal root system nor a mycorrhizal network are enough to stage nutrient flow; they must intertwine with each other.—oxytonic on 2024-01-08

Luhmann's system wasn't very unique (really only in his filing system) compared with the thousands of others in use at the time or for centuries prior. The more interesting space of intertwining is between the ideas in the box and those held in memory and worked on in coordination with the brain. Too many get wrapped up in his physically visible box and forget the work done by the by the "invisible" brain.

X17-Mind-Papers - die Wiederentdeckung der Karteikarte<br /> https://www.youtube.com/watch?v=wxZMia35usc

Mind Papers has a variety of small leather covers (folders) with binder clips for storing one's note cards. They range from smaller than A7 up to A5 sizes.

They're broadly reminiscent of smaller versions of the Everbook, though I suspect these came first given the 2014 post date.

Update 2024-01-04: I knew I had heard/seen this system before, but not delved into it deeply. I hadn't seen anyone either using it or refer to it by name in the wild until yesterday. All the prior mentions were people sharing the URLs as a thing rather than as something they used.

It Took Decades To Create This Chess Puzzle Database (30 Thousand), 2020. https://www.youtube.com/watch?v=Y9craX0M_2A.

A chess School named after Genrikh Kasparyan (alternately Henrik Kasparian) houses his card index of chess puzzles with over 30,000 cards.

The cards are stored in stacked wooden trays in a two door cabinet with 4 shelves.

There are at least 23 small wooden trays of cards pictured in the video, though there are possibly many more. (Possibly as many as about 35 based on the layout of the cabinet and those easily visible.)

Kasparyan's son Sergei donated the card index to the chess school.

Each index card in the collection, filed in portrait orientation, begins with the name of the puzzle composer, lists its first publication, has a chess board diagram with the pieces arranges, and beneath that the solution of the puzzle. The cards are arranged alphabetically by the name of the puzzle composer.

The individual puzzle diagrams appear to have been done with a stamp of the board done in light blue ink with darker blue (or purple?) and red inked stamped pieces arranged on top of it.

Wish You Were Here - The “Great Lakes” Edition from Field Notes Brand https://www.youtube.com/watch?v=fFemm4LjJbY

The Newberry Library in Chicago, IL, maintains a collection of the Curt Teich & Co.'s Art-Colortone postcards from 1898 onward. It's stored in tab divided boxes using an alpha-numeric system generally comprising a series of three letters followed by three numbers. The company sold over a billion of these postcards.

I accomplished a couple of other things on that first day back into reality. First, with an evil Grinch-like smile | uprooted every household management system | had ever tried, and tore up every single 3x5 card in them. Then one by one, | roasted and toasted them in the fireplace until they were gone, gone, gone. Next, with equally fiendish delight, | speared my $35 namebrand notebook organizer with a marshmallow fork, and | roasted it too. It melted into oblivion, all but it’s ugly metal spine. Next, | prayed for my attitude and for help. And finally, | marched myself into Wal-mart and bought my first clear plastic bin, a two pound sack of M&M's, and a loaf of white bread. For better or worse, we have been pretty happy campers at my house ever since. (p6)
