This is similar to the idea of edge notched cards, but is done visually instead of cutting the cards. It's also seen in the Pile of Index Card method which uses a variety of marks on gridded cards.

Hawk Sugano uses a wastebook-like process to take contemporaneous notes in a pocket notebook and later transfers the ideas to index cards for follow up and filing.

Hawk Sugano was introduced to index cards circa 2001 by means of Watanabe Shoichi's book “知的生活の方法” (A Method of Intellectual Life".

Hawk Sugano apparently offered the Pile of Index Cards as a physical product offering by combining Correct's index card dock and Kokuyo's fieldnotes in late December 2006.

Hawk considered PoIC a "software" and licensed it as such. :)

ᔥ[[hawkexpress]] in How to link between Cards

Hawk Sugano's Pile of Index Cards method is laid out visually in his Flickr account using photos of several of his cards along with descriptions of what each is for and how they work.

These include: 0. PoIC Format/Template 1. Record Card 2. Discovery Card 3. GTD Card 4. Cite Card 5. How to link between cards

<small><cite class='h-cite via'>ᔥ <span class='p-author h-card'>Manfred Kuehn</span> in Taking note: Luhmann's Zettelkasten (<time class='dt-published'>08/06/2021 00:16:23</time>)</cite></small>

Note the use of the edge highlighted taxonomy system used on these cards:

Similar to the so called high five indexing system I ran across recently.

https://www.flickr.com/photos/hawkexpress/192480328/in/album-72157594200490122/

The PoIC system allows linking of cards using date/timestamps for indexing/finding. Interestingly they were all kept in chronological order rather than in idea order as in Luhmann's zettelkasten.

What are the pros/cons of this?<br /> - more searching and hunting through cards certainly is a drawback for lack of "threaded" ideas - others...

hawkexpress apparently learned this technique on the 2-channel.

Despite being used primarily as a productivity tool the PoIC system also included some features of personal knowledge management with "discovery cards" and "citation cards". Discovery cards were things which contained one's own ideas while the citation cards were the ideas of others and included bibliographic information. Citation cards were tagged on the 5th block as an indicator within the system.

Question: How was the information material managed? Was it separate from the date-based system? On first blush it would appear not, nor was there a subject index which would have made it more difficult for one to find data within the system.

Introduction to the Pile of Index Cards method.

These are more similar to zettelkasten and commonplacing traditions. They comprise the majority of the system.

Interesting to see a passing mention of Hawk Sugano's Pile of Index Cards here in a note taking context rather than a productivity one.

Interesting to see a somewhat out of place link to Pile of Index Cards system here.

Given the 2015 date of the post this could be a part of the small distribution of the 2006 idea into the conversation a decade later.

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...

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.

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.

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?
