Esparmer is correct that research and writing did change with the advent of word processors and the internet in the 1990s and early 2000s (p xi), but these were primarily changes to the front and the back of the process. Esparmer and far too many others seem to miss the difference in which affordances were shifting here. The note taking and organization portions still remained the same, so Eco's advice is still tremendously important. Even if one were to do long form notes in notebook format or in digital documents, they would profitably advised to still properly cross-index their notes or have them in a form that allows them to rearrange them most simply with respect to the structuring and creative processes.

Losing the ability to move ideas around easily, restructure them, link them together and outline them was a tremendous blow in going from the old methods to the new digital ones.

Did we accidentally become enamored of the new technologies and forget that their affordances didn't completely replace those of the old methods?

Instead of using pre-made stiff index cards, Luhmann used standard paper which he cut up into DIN A6 sized slips which he packed into his drawers. Schmidt had trouble removing slips from some of the boxes because they were packed so tightly.

Exactly how much space would be saved writing on standard paper versus index cards in a collection as large as Luhmann's?

Manfred Kuehn's index card commonplace from 1974 - 1985

At 5 - 6,000 cards in 11 years from 1974 to 1985, Kuehn would have made somewhere in the neighborhood of 1.25 - 1.49 note per day.

His description of paragraphs from 150 to 350 words is interesting with respect to the amount of material that will fit on a 3x5" inch card during the note taking process.

Every card has holes pre-punched into it in exactly the same place (see the photo in the original post at the top) so that one might put a knitting needle (or other thin instrument) through the whole deck in each of the positions. Then one should decide on what each hole's meaning will be by position.

As an example, imagine you're using your cards in a rolodex fashion and you want to distinguish the six categories: family, friends, service providers, neighbors, co-workers, and organizations/businesses. For family members you cut/remove the additional paper between the first hole (representing "family") and the edge of the paper. You do the same thing for all the other cards based on their respective categories. So, for example, your brother Joe who lives across the street from you and works with you at the office in the family business would have cuts removed for positions 1, 4, and 5. For an entity that fits all six categories, cuts would be made such that the sheet would no longer stay in u/I-love-teal (the original poster's) six ring binder notebook.

At the end of the year you want to send Christmas cards to your friends, family and neighbors, so you put the knitting needles into position 1 and pull up separating your family out, then you repeat for positions 4 and 5 until you have your full list. (Pro tip: you probably wouldn't want to pull them out of the deck completely, but might rather pull them up and set them at a 90 degree angle thus preventing you from needing to do the work of refiling them all in a particular order.)

Obviously if you have multi-row edge punches or dozens of edge notches you can discern a lot more categories or data types using basic logic. Just abstract this to your particular note card system. Herman Hollerith used this in early versions of the U.S. Census in the late 1800s and it and variations were used heavily in early computer programming applications.

A variation of this sort of trick can also be done by coloring in (or not) the edges of parts of your cards as well. See for example the general suggestions in these photos which help to layout the idea of the "Pile of Index Card" system used back in 2006 with respect to Getting Things Done (GTD) philosophy:

• https://www.flickr.com/photos/hawkexpress/189967397/
• https://www.flickr.com/photos/aki_oda/2684257358
• https://www.flickr.com/photos/hawkexpress/189972896

On my mathematics specific notes which I generally put on graph paper cards, I use colored edge "notches" like these to represent broad categories like theorems, proofs, definitions, corollaries, etc. or method of proof (induction, direct, contradiction, contraposition, construction, exhaustion, probabilistic, combinatorial, etc.) This makes finding specific cards a bit easier as I tip through various sections.

A historian might use colored edges to visually label dates by decades or centuries depending on the timespan of their studies. The uses can be endless and can be specific to your field of study or needs.

Some might also attach the idea of tags/categories to the colors of their cards, so you might use white cards for ideas which are your own, yellow cards which are quotes of others' material, blue cards which represent synopses of other's ideas, etc. One might also profitably use a multi-pen with different colored inks to represent these sorts of meta-data as well.

The variations are endless...

If you really want to go crazy you can get 6-hole punches to make your own cards.

And if you like you can co-opt those holes in your notebox by using them for taxonomy terms and removing/or not the connective pieces to indicate membership of a group. Then by putting a knitting needle through large groups of cards, you can sort through your collection to find related items the way they used to in early computing with edge-notched cards. 😉🗃️

reply to IvanFerrero at https://forum.zettelkasten.de/discussion/1740/anybody-using-this-approach-to-manage-contacts-how#latest

Many of the digital note taking tools that run off of text allow you to add metadata to your basic text files (as YAML headers, inline with a key:: value pair, or via #tags). Many of them have search functionality or use other programmatic means like query blocks, DataView, DataViewJS, etc. for doing queries on your files to get back lists, tables, charts, etc. of the data you're looking for.

The DataView repository has some good examples of how this works with something like Obsidian. Fortunately if you're using simple text files you can usually put them into one or more platforms to get the data and affordances you want out of them individually.

As an example, I have a script block in my daily note in Obsidian for birthdays in my notes that fall on today's date:

```dataview LIST birthday FROM "Lists/People" WHERE birthday.day = date(2023-01-18).day ```

If I put the text birthday:: 1927-12-08 into a note about Niklas Luhmann, his name and birthday would appear in my daily note on his birthday. One can use similar functionality to create tables of books they read with titles, authors, ratings, dates read, etc. or a variety of other data input which parses through your plaintext files. Services like Obsidian, Logseq, et al. are getting better about allowing these types of programmatic searches for users without backgrounds in programming and various communities usually provide help for pre-made little snippets like the one above that one can cut and paste into their notes to get the outputs that they need. Another Obsidian based example that uses text files for tracking academic journal articles can be found at https://nataliekraneiss.com/your-academic-reading-list-in-obsidian/; I'm sure there are similar versions for other text-based platforms.

In pre-digital times, for a manual version of a rolodex like this in paper, one could use different color cards as pseudo-tags (doctors are on yellow cards, family members on blue cards, friends on green cards, etc.) or adding edge notches or even tabs to represent different types of metadata. See for example the edge colored cards in Hawkexpress' Pile of Index Cards: https://www.flickr.com/photos/hawkexpress/albums/72157594200490122

Here again he comes close to some of the methods and ideas of having flashcards for spaced repetition, but isn't explicitly aware of the words or techniques. Note that he also doesn't use the word flashcard. When was the word first used?

Rewriting things as flashcards also tends to be a part of the spaced repetition itself.

By cutting the notes up he's specifically decontextualizing them so as to make one's memory be better tested in coming up with the solutions/answers as they are more likely to appear on a test, decontextualized from the original lecture.

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.

Try Kaitiaki or Rite in the Rain. If you search for "index card wallet" you'll likely find a variety of others, including some custom made versions on sites like Etsy. 3 x 5" are relatively common, but 4 x 6" are much harder to come by.

Goitein's zettelkasten is comprised of about 20,000 3 x 5" index cards and 7,000 5 x 8" index cards.

Link to: https://hypothes.is/a/TEiQ5H1rEe2_Amfzi4XXmg

While not directly confirmed (yet), due to the seeming correspondence of the number of cards and their corpus descriptions, it's likely that the 20,000 3 x 5" cards were his notes covering individual topics while the 7,000 5 x 8" cards were his notes and descriptions of a single fragment from the Cairo Geniza.

In addition to writing on cards, Goitein also wrote notes on pieces of paper that he happened to have lying around.

Joan Rivers had an index card catalog with 52 drawers of 4-by-6-inch index cards containing jokes she'd accumulated over her lifetime of work. She had 18 2 drawer stackable steel files that were common during the mid-1900s. Rather than using paper inserts with the label frames on the card catalogs, she used a tape-based label maker to designate her drawers.

Note carefully that the article says 52 drawers, but the image in the article shows a portion of what can be surmised to be 18 2-drawer cabinets for a total of 36 drawers. (14 2-drawer cabinets are pictured, but based on size and perspective, there's one row of 4 2-drawer boxes not shown.)

PVA Glue used in bookbinding, but isn't inexpensive.

• Tacky glue - okay
• rubber cement - not great
• elmer's glue - not great, tears esp. for 2 layers
• Mod podge - pulls nicely and strong
• mod podge hard shell - cracks, not great
• PVA Glue - the best of the group

Recommendations in order: PVA, Tacky Glue, Mod Podge (regular)

Brush on top edge and do two coats. Don't get it down between sheets.

Victor Margolin's note taking and writing process

• Collecting materials and bibliographies in files based on categories (for chapters)
• Reads material, excerpts/note making on 5 x 7" note cards
  • Generally with a title (based on visual in video)
  • excerpts have page number references (much like literature notes, the refinement linking and outlining happens separately later in his mapping and writing processes)
  • filed in a box with tabbed index cards by chapter number with name
  • video indicates that he does write on both sides of cards breaking the usual rule to write only on one side
• Uses large pad of newsprint (roughly 18" x 24" based on visualization) to map out each chapter in visual form using his cards in a non-linear way. Out of the diagrams and clusters he creates a linear narrative form.
• Tapes diagrams to wall
• Writes in text editor on computer as he references the index cards and the visual map.

"I've developed a way of working to make this huge project of a world history of design manageable."<br /> —Victor Margolin

Notice here that Victor Margolin doesn't indicate that it was a process that he was taught, but rather "I've developed". Of course he was likely taught or influenced on the method, particularly as a historian, and that what he really means to communicate is that this is how he's evolved that process.

"I begin with a large amount of information." <br /> —Victor Margolin

"As I begin to write a story begins to emerge because, in fact, I've already rehearsed this story in several different ways by getting the information for the cards, mapping it out and of course the writing is then the third way of telling the story the one that will ultimately result in the finished chapters."<br /> —Victor Margolin

If the statistical heterogeneity is larger that what's expected by chance alone, then what does that imply? That there's either clinical or methodological heterogeneity within the pooled studies.

What's the impact of the presence of clinical heterogeneity? The statistical heterogeneity (variation of effects/results of interventions) becomes greater than what's expected by chance alone

What's happens if methodological heterogeneity is present? The statistical heterogeneity (variation of effects/results of interventions) becomes greater than what's expected by chance alone

I used to do this sort of practice before, but I used buckslips instead.

Frederic L. Paxson kept a collection of 3 x 5 " slips of thin paper that filled eighty wooden file drawers which he organized using topical-chronologic headings spanning 4639 BCE to 1949.

France, Anatole. L’Île Des Pingouins. Project Gutenberg 8524. 1908. Reprint, Project Gutenberg, 2005. https://www.gutenberg.org/cache/epub/8524/pg8524.html

Death by Zettelkasten!!

(Coming soon to a theater near you...)

In the preface to the novel Penguin Island (L'Île des Pingouins. Calmann-Lévy, 1908) by Nobel prize laureate Anatole France, a scholar is drowned by an avalanche of index cards which formed a gigantic whirlpool streaming out of his card index (Zettelkasten).

Link to: Historian Keith Thomas has indicated that he finds it hard to take using index cards for excerpting and research seriously as a result of reading this passage in the satire Penguin Island.<br /> https://hypothes.is/a/rKAvtlQCEe2jtzP3LmPlsA

Translation via: France, Anatole. Penguin Island. Translated by Arthur William Evans. 8th ed. 1908. Reprint, New York, NY, USA: Dodd, Mead & Co., 1922. https://www.google.com/books/edition/Penguin_Island/6UpWAvkPQaEC?hl=en&gbpv=0

Small changes in the translation by me, comprising only adding the word "index" in front of the occurrences of card to better represent the historical idea of fiches used by scholars in the late 1800s and early 1900s, are indicated in brackets.

The walls of the study, the floor, and even the ceiling were loaded with overflowing bundles, paste board boxes swollen beyond measure, boxes in which were compressed an innumerable multitude of small [index] cards covered with writing. I beheld in admiration mingled with terror the cataracts of erudition that threatened to burst forth.

“Master,” said I in feeling tones, “I throw myself upon your kindness and your knowledge, both of which are inexhaustible. Would you consent to guide me in my arduous researches into the origins of Penguin art?"

“Sir," answered the Master, “I possess all art, you understand me, all art, on [index] cards classed alphabetically and in order of subjects. I consider it my duty to place at your disposal all that relates to the Penguins. Get on that ladder and take out that box you see above. You will find in it everything you require.”

I tremblingly obeyed. But scarcely had I opened the fatal box than some blue [index] cards escaped from it, and slipping through my fingers, began to rain down.

Almost immediately, acting in sympathy, the neighbouring boxes opened, and there flowed streams of pink, green, and white [index] cards, and by degrees, from all the boxes, differently coloured [index] cards were poured out murmuring like a waterfall on a mountain-side in April. In a minute they covered the floor with a thick layer of paper. Issuing from their in exhaustible reservoirs with a roar that continually grew in force, each second increased the vehemence of their torrential fall. Swamped up to the knees in cards, Fulgence Tapir observed the cataclysm with attentive nose. He recognised its cause and grew pale with fright.

“ What a mass of art! ” he exclaimed.

I called to him and leaned forward to help him mount the ladder which bent under the shower. It was too late. Overwhelmed, desperate, pitiable, his velvet smoking-cap and his gold-mounted spectacles having fallen from him, he vainly opposed his short arms to the flood which had now mounted to his arm-pits . Suddenly a terrible spurt of [index] cards arose and enveloped him in a gigantic whirlpool. During the space of a second I could see in the gulf the shining skull and little fat hands of the scholar; then it closed up and the deluge kept on pouring over what was silence and immobility. In dread lest I in my turn should be swallowed up ladder and all I made my escape through the topmost pane of the window.

Relying on cut up slips of paper rather than the standard cards of equal size, Keith Thomas has relayed that his slips often "get loose and blow around the house, turning up months later under a carpet or cushion."

He also suspects that some of his notes have accidentally been thrown away by falling off his desk and into the nearby waste basket which camouflages his notes amongst similar looking trash.

In Penguin Island, Anatole France describes a scholar drowned by an avalanche of their own index cards!

reply to u/m_t_rv_s__n https://www.reddit.com/r/Zettelkasten/comments/y2pzuu/does_anyone_else_work_in_projectbased_systems/

Historically, many had zettelkasten which were commonplace books kept on note cards, usually categorized by subject (read: "folders" or "tags"), so you're not far from that original tradition.

Similar to your work pattern, you may find the idea of a "Pile of Index Cards" (PoIC) interesting. See https://lifehacker.com/the-pile-of-index-cards-system-efficiently-organizes-ta-1599093089 and https://www.flickr.com/photos/hawkexpress/albums/72157594200490122 (read the descriptions of the photos for more details; there was also a related, but now defunct wiki, which you can find copies of on Archive.org with more detail). This pattern was often seen implemented in the TiddlyWiki space, but can now be implemented in many note taking apps that have to do functionality along with search and tags. Similarly you may find those under Tiago Forte's banner "Building a Second Brain" to be closer to your project-based/productivity framing if you need additional examples or like-minded community. You may find that some of Nick Milo's Linking Your Thinking (LYT) is in this productivity spectrum as well. (Caveat emptor: these last two are selling products/services, but there's a lot of their material freely available online.)

Luhmann changed the internal structure of his particular zettelkasten that created a new variation on the older traditions. It is this Luhmann-based tradition that many in r/Zettelkasten follow. Since many who used the prior (commonplace-based) tradition were also highly productive, attributing output to a particular practice is wrongly placed. Each user approaches these traditions idiosyncratically to get them to work for themselves, so ignore naysayers and those with purist tendencies, particularly when they're new to these practices or aren't aware of their richer history. As the sub-reddit rules indicate: "There is no [universal or orthodox] 'right' way", but you'll find a way that is right for you.

The original PoIC didn't include bi-directional links, but the idea was brought up and considered.

What are these references to Umedao and Buhmann? Quck searches don't yield much. Need to look deeper.

Brief explanation of the Pile of Index Cards system, but without significant depth.

As is apparently often in describing new organizing systems (commonplace books, zettelkasten, PoIC, etc.), not everyone is going to understand it the first time, or even understand what is going on or why one would want to use it.

This post by Susan is such an example.

Susan does almost immediately grasp that this might be something one could transfer into a digital system however, particularly for the search functionality.

https://web.archive.org/web/20110714192833/http://pileofindexcards.org/wiki/index.php?title=43Tabs_System

Several months back I'd thought about adapting the 43 folders system to a zettelkasten sort of system. I'm obviously not the first to have done so.

LifeHacker covers the Hawk Sugano's Pile of Index Cards method, which assuredly helped promote it to the GTD and productivity crowd.

One commenter notices the similarities to Ryan Holiday's system and ostensibly links to https://thoughtcatalog.com/ryan-holiday/2013/08/how-and-why-to-keep-a-commonplace-book/

Two others snarkily reference using such a system to "keep track of books in the library [,,,] Sort them out using decimal numbers on index cards in drawers or something..." and "I need to tell my friend Dewey about this! He would run with it." Obviously they see the intellectual precursors and cousins of the method, though they haven't looked at the specifics very carefully.

One should note that this may have been one of the first systems to mix information management/personal knowledge management with an explicit Getting Things Done set up. Surely there are hints of this in the commonplace book tradition, but are there any examples that go this far?

I would echo Bob's sentiment here and would recommend you keep that material like this in a separate section or box all together.

If it helps to have an example, in 2006, Hawk Sugano showed off a version of a method you may be considering which broadly went under the title of Pile of Index Cards (or PoIC) which combined zettelkasten and productivity systems (in his case getting things done or GTD). I don't think he got much (any?!) useful affordances out of mixing the two. In fact, from what I can see looking at later iterations of his work and how he used it, it almost seems like he spent more time and energy later attempting to separate and rearrange them to get use out of the knowledge portions as distinct from the productivity portions.

I've generally seen people mixing these ideas in the digital space usually to their detriment as well—a practice I call zettelkasten overreach.

An example of a ticker file in the vein of getting things done (GTD) documented using index cards and a card file from 1917. Sounds very familiar to the Pile of Index Cards (PoIC) from the early 2000s.

Interesting to see the first post on zettelkasten.de in 2013 has a photo of hawkexpress' Pile of Index Cards (PoIC) in it.

This obviously means that Christian Tietze had at least a passing familiarity with that system, though it differed structurally from Luhmann's version of zettelkasten.

1. BNF, NAF 28630, ‘Grand fichier’, 3 January 1975.

Roland Barthes' biographer Tiphaine Samoyault quotes portions of what he calls Barthes' card index diary.

This can also be seen in the published cards which comprise Barthes' Mourning Diary about the period following his mother's death.

Are there other people who've used their card index as a diary the way that some use it for productivity?

Find this quote and context!

Apparently a colleague wrote about Deutsch's "game of cards" as a description of hit use of a zettelkasten. The play here is reminiscent of the joy Ahrens talks about when doing research/reading/writing (2017).

Dwyer, Edward J. “File Card Efficiency.” Journal of Reading 26, no. 2 (1982): 171–171.

Ease of use in writing and grading with short assignments by using 4 x 6" index cards in classrooms.

This sounds like some of the articles from 1912 and 1917 about efficiency of card indexes for teaching.

I'm reminded of some programmed learning texts that were card-based (or really strip-based since they were published in book form) in the 1960s and 1970s. Thse books had small strips with lessons or questions on the front with the answers on the reverse. One would read in strips through the book from front to back and then start the book all over again on page one on the second row of strips and so on.

Unlike many manuals on note taking, Goutor suggest a few methods of note categorization beyond adding typical headwords. These include adding top or side edge notches using a paper punch, colored cards, or adding colored flags. However he does note some potential problems and limitations of these methods including being cumbersome or limiting (by colors available, for example). (p31-32)

For the second time Goutor mentions using different size cards for different note types, but doesn't specifically advise for it or provide a reason. Perhaps his advice for consistency and card size applies only to cards of particular types? (p28)

link to: https://hypothes.is/a/XPphjkNZEe2s3i9VV4qt1g

Incidentally he also specifically mentions 7x9" cards here too. How frequently used were these as a standard?

While he previously recommended using note cards of the same size, the examples in Goutor (1980) have 3x5" cards for bibliographic notes and 5x7" or larger cards for content notes. (p19, 21)

Is there a reason stated anywhere here for this discrepancy or change? One would ostensibly keep them in different places/sections of one's card index, but does the size difference help to differentiate the two to aid in sorting? Is the larger card intended to hold more long form writing?

Goutor is in Canada, so were 5x7" cards more common or standardized there in the late 1970s and early 80s?

A5 measures 148 × 210 millimeters or 5.83 × 8.27 inches, so is a bit larger than 5x7".

5x7" is a more standard photo size, so was this chosen as the result of storage options from the photography space?

5x7" is scantly available in America in 2022, but only from Hamilco. A few others make cardstock in that size but not specifically as index cards.

Goutor comments, like many before him, that it is common to take notes on notebook paper in longer form, but that this is inadvisable as it is much harder to impose a useful order or classification on such work. He does mention scissors as a means of cutting up such notes, but comments that "a mass of slips of paper of varying sizes [can be] difficult to arrange and potentially useless unless care has been taken to note the source of each separate entry."

He also repeats the frequent admonitions that one should take notes only on one side and to use cards of a uniform size.

(p6)

Notice that it's not just notes, but data on IBM cards that he's using for research here. This sort of data analysis is much easier now, but is also of the sort detailed by Beatrice Webb in her scientific note taking.

While it may be slightly more difficult to find larger metal/wood cases for the 4x6 or 5x8 cards, it's a minor nuisance and anyone who wants them will eventually find the right thing for them. Beyond this, choose the card size that feels right to you.

If you don't have an idea of what you need or like, try things out for 10-20 cards and see how it works for you, your handwriting size, and general needs. People have been using 3x5, 4x6, and even larger for hundreds of years without complaining about any major issues. If Carl Linnaeus managed to be okay with 3x5, which he hand cut by the way, I suspect you'll manage too.

Of course I won't mention to the Americans the cleverness of the A6, A5, A4 paper standards which allows you to fold the larger sizes in half to get the exact next smaller size down. Then you might get the benefit of the smaller size as well as the larger which could be folded into your collection of smaller cards, you just have to watch out for accidentally wrapping ("taco-ing") a smaller card inside of a larger one and losing it. I suppose you could hand cut your own 5" x 6" larger cards to do this if you found that you occasionally needed them.

For the pocketbook conscious, 3x5 does have the benefit of lower cost as well as many more options and flexibility than larger sizes.

At least commercial card sizes are now largely standardized, so you don't have deal with changing sizes the way Roland Barthes did over his lifetime.

My personal experience and a long history of so many manuals on the topic saying "cards of the same size" indicates that you assuredly won't have fun mixing different sized slips together. I personally use 3x5" cards in a waste book sense, but my main/permanent collection is in 4x6" format. Sometimes I think I should have done 3 x 5, but it's more like jealousy than regret, particularly when it comes to the potential of a restored fine furniture card catalog. But then again...

Joseph Harris uses a mélange of materials to make his writing including books, papers, magazines, from which he is copying sections out, writing in margins, making notes on index cards and then moving those pieces of text and pieces of paper (the index cards, and possibly Post-it notes) around to create his output.

He doesn't delineate a specific process for his excerpting or note taking practice. How does he organize his notes? Is he just pulling them from piles around him? Is there a sense of organization at all?

https://web.archive.org/web/20080412071219/http://eastgate.com/catalog/Briefcase.html

Eastgate systems used to make a "3x5 Card Briefcase" to capture short notes on the go which could later "be scanned or transcribed to Tinderbox."

Tinderbox was one of the first digital tools to be used in a way very similar to zettelkasten of old, particularly by academics, who are a large portion of their power user base.

Circa late 2011, he's positing Luhmann had 35,000 cards and not 90,000.

Jules Verne used index cards. Joachim Jungius is said to have had 150,000 cards.

https://web.archive.org/web/20140707053048/http://www.getfrictionless.com/products/capture-cards-red

Simple index cards, but sold with a purpose in mind: capturing notes!

One is reminded here of waste books and fleeting notes.

I've been spelunking through your posts from roughly the decade from 2005 onward which reference your interest in index cards. Thanks for unearthing and writing about all the great index card material from that time period. Have you kept up with your practices?

I noticed that at least one of your posts had a response by MK (Manfred Kuehn, maintainer of the now defunct Taking Note blog (2007-2018). Was it something you read at the time or kept up with?

Have you been watching the productivity or personal knowledge management space since roughly 2017 where the idea of the Zettelkasten (slip box or card index) has taken off (eg. https://zettelkasten.de/, Sonke Ahren's book How to Take Smart Notes, Obsidian.md, Roam Research, etc.?) I'd be curious to hear your thoughts on them or even what your practice has meant over time.

Thanks again.

Cheers! -CJA

The documentary Casting By (2012) shows casting director Marion Dougherty's 3 x 5" index card collection which she used for casting notes. In particular they show an example card for Dustin Hoffman with his details. In Hoffman's case, his card included the older telephone numbers with exchanges (EN2-6933 or Endicott2 6933), so these cards may have also served a contact purpose similar to more modern rolodexes. Different from them however, Dougherty's also included heights, credits, and other observations relevant to the casting process.

Walmart has these index cards, but only in 3x5" format.

What size index cards did Vladimir Nabokov use?

See also: series of Nabokov photos of him and index cards.

Nabokov's wishes were that his heirs burn the index cards on which he had handwritten the beginning of his unfinished novel The Original of Laura. His wife Vera, not able to destroy her husband's work, couldn't do it, so the decision fell to their son Dimitri. Having translated many of his father's works previously, Dimitri Nabokov ultimately allowed Penguin the right to publish the unfinished novel.

This is 4-1/8 x 5-7/8 in which is close to the American 4x6 inch index card.

Or roughly 4 x 6".

paper over card in terms of sheet thickness, particularly over time

Interesting choice of translation for "Die Kartei" by the translator. Some may have preferred the more direct "file".

Historically for this specific time period, while index cards were becoming more ubiquitous, most of the prior century researchers had been using larger sheets and frequently called them either slips or sheets based on their relative size.

Beatrice Webb in 1926 (in English) described her method and variously used the words “cards”, “slips”, “quarto”, and “sheets” to describe notes. Her preference was for quarto pages which were larger pages which were likely closer to our current 8.5 x 11” standard than they were to even larger index cards (like 4 x 6".

While I have some dissonance, this translation makes a lot of sense for the specific time period. I also tend to translate the contemporaneous French word “fiches” of that era as “sheets”.

See also: https://hypothes.is/a/OnCHRAexEe2MotOW5cjfwg https://hypothes.is/a/fb-5Ngn4Ee2uKUOwWugMGQ

A benefit of 4 x 6" cards is that clippings and other items can often be more easily filed along with them as opposed to the smaller 3 x 5" cards.

Dow indicates in 1924 that 3 x 5" and 4 x 6" are both commonly had in a range of materials the US as well as boxes or cases to keep them in. He does mention that one can also cut their own paper, indicating that this is a possibility.

With the standardization of index cards for the filing boxes of his own manufacture, Dewey earned himself the further development of the routing techniques without earning anything with it. In order to prevent economic ruin, the Library Bureau switched its own bookkeeping from the traditional accounting system to the faster and more cost-effective system of the "card index" in 1888. The "technology transfer between library and office" (Krajewski), namely bookkeeping in card boxes, is a hit: banks and insurance companies, steel and railway companies take over the card system and thus also the card boxes from Dewey's company.

This is a fascinating way of making one's product indispensable. Talk about self-dogfooding!

Sounds similar to the way that some chat messaging productivity apps were born (Slack was this way?). The company needed a better way to communicate internally and so built it's own chat system which they sold to others.

Here Blair quotes Chavigny and Heyde, but crucially leaves out Bernheim, Langlois & Seignobos, and Beatrice Webb.

Check the others, specifically for index card references, but Webb uses slips or sheets (and often larger ones).

The transcription on this from .pdf via Hypothesis is dreadful! In particular for the card sizes. The actual text reads as:

1. Devices for note-taking. In taking notes of reading, use slips of paper the size of the standard library card (3 x5 in.). For more extended notes and for typewritten notes, the standard half-sheet (5 1/2 x 8 1/2 in.) is usually the most satisfactory size. For special purposes still larger sheets are sometimes essential. In any extended investigation the use of different colored slips or different colored inks for certain classes of notes will often prove a convenient and time-saving device. It is especially desirable, thus, to distinguish bibliographical data from subject matter. Each slip should contain only a single note. Put a topical heading at the top of each slip of subject notes and a reference to the volume and page of the authority quoted.

sugane brierre and otlet<br /> "everything can be in a document"<br /> importance of evidence

The idea of evidence implies a passiveness. For evidence to be useful then, one has to actively do something with it, use it for comparison or analysis with other facts, knowledge, or evidence for it to become useful.

transformation of sound into writing<br /> movement of pieces at will to create a new combination of facts - combinatorial creativity idea here. (circa 27:30 and again at 29:00)<br /> not just efficiency but improvement and purification of humanity

put things on system cards and put them into new orders<br /> breaking things down into smaller pieces, whether books or index cards....

Otlet doesn't use the word interfaces, but makes these with language and annotations that existed at the time. (32:00)

Otlet created diagrams and images to expand his ideas

Otlet used octagonal index cards to create extra edges to connect them together by topic. This created more complex trees of knowledge beyond the four sides of standard index cards. (diagram referenced, but not contained in the lecture)

Otlet is interested in the "materialization of knowledge": how to transfer idea into an object. (How does this related to mnemonic devices for daily use? How does it relate to broader material culture?)

Otlet inspired by work of Herbert Spencer

space an time are forms of thought, I hold myself that they are forms of things. (get full quote and source) from spencer influence of Plato's forms here?
