The past year I’ve had more conversations about personal knowledge management than for a long time before. Regularly questions come up along the lines of what structures should one use, what should one keep in their notes, what are the best tools? Most of my contributions to such conversations boil down to ‘there’s nothing you should do other than what fits you, and I could show you what I do and why that works for me’.
Ultimately I keep thinking people don’t take the P in PKM far enough. I think PKM is personal not just in one way, but in at least three ways.

  1. It is personal knowledge management in the sense that your system is yours only. You do it, build and extend it as you see fit. It can exist independently of whatever other working environments you have, it is fully personally yours. This enables and secures your professional and learning autonomy, allows you to be pro-active. You bring professionalism to its upkeep and tools. When you go someplace else, you take it along with you.
  2. It is management of your personal knowledge. Personal knowledge in the sense of your own networks of meaning, your insights, the expressed connections you made between pieces of it, your associations and verbiage that tie into your internal world. It exists to feed your agency, your combinatory creativity, and is aimed at your own mix of evolving personal interests. It’s there for just you to interact with. This allows you to steer the direction of your own learning intentionally, and enables an activist and artisanal stance towards your interests, professional or otherwise. Your personal knowledge doesn’t need to be understandable or be useful to others. Sharing in context is an act in itself, an output rather than a function.
  3. It is personal management of knowledge. You have your own methods and structures, that are geared to how you work, think, learn and create best, and which have emerged over time and you then reinforced because of their utility to you. You create your own mechanisms and algorithms working with your material, and reflect on them. Your system does not need to be understandable or workable for others. Your structures fit your internal world, have their logic and starting point in the fact that your behaviour is pretty predictable to yourself at least. Some of the structures in your system may well be just in your head rather than made tangible in your external system. Some structures may be intentionally omitted to ensure you can surprise yourself with your system, feeding discovery and wonder.

I can’t tell you how to do PKM, I can show you what does and doesn’t work for me and tell you why I think that is. I will tell you to take PKM very personally, and then some more.

Bookmarked Tools for Thought Library in Zotero (by Chris Aldrich)

This large and interesting collection of books, writings, quotes and other artefacts on note making and personal knowledge management, tools for thought in short, through the ages is something to explore at leisure. It seems to have been put together by Chris Aldrich some two years ago. Great stuff. Came across it in Chris’s Hypothes.is stream, and didn’t immediately realise it was a reference to his own collection.

Working on a visual representation of the European data strategy landscape, integrated as well as alongside a textual representation this morning. It makes for a pleasant experience. The experience comes from what Zsolt Viczián’s Excalidraw plugin for Obsidian allows me to do, something I mentioned here earlier after the PKM Summit last March where Zsolt showed this.

Excalidraw drawings are basically text files describing the drawing, which are then rendered in the viewer. What the plugin supports is putting other text elements outside the drawing elements, and exclude them from the visual view. This creates two representations of the same file: one the drawing presented visually, one the text content outside the visual. Zsolt calls it the ‘flip side’ of a drawing, being a note accompanying the drawing. I see it more like two different views on the same thing. I have a hotkey (cmd arrow down) enabled to flip a note between both views.

Putting both views next to each other, and working in both at the same time, allows me a seamless mode of working, switching between visual material and text writing. As shown in the screenshot below.

Here you see the same note twice, opened in two tabs. The left side is the textual representation. It also contains an embedded auto-generated image from the visual representation but that is something I choose to do. Underneath that image you see some notes I wrote.
The right hand side shows the visual representation, a drawing of how I perceive the context of the European single market for data (at least, part of it).
I use the visual side as a Systems Convening landscape, to think about barriers, possible interventions, visibility etc. I use the text side to turn those thoughts into notes, potential actions, and links to other relevant material, or to write down things I think might be added to the visual.

Over the years my main problem with working more visually has been the lack of fluidity between the visual and the textual. Basically rendering them into two separate silos. Few tools solve that issue (Tinderbox is one). This means I usually favor the textual side of things. Where I use images, they are ‘frozen’ moments of the ever evolving textual side. The set-up this morning is not silo’d and here the creation of visual elements aids the text creation and vice versa, while I work on both in parallel in a single note. Both text and visual evolve together. Very nice.

Bookmarked Latticework: Unifying annotation and freeform text editing for augmented sensemaking by Matthew Siu and Andy Matuschak

Back in early February I got a chance to work with a beta tool for sense making in my notes. See my impressions at the time. Matthew Siu and Andy Matuschak watched me for an hour as I used their prototype tool to start shaping a workshop design from various inputs. I was intrigued and enthusiastic, but a few weeks later due to some tech glitches I stopped using it. Today Maarten den Braber in an e-mail pointed me to Latticework from last June, describing the project as it stood at the end. It’s an interesting read, which I annotated (if you read those annotations, start at bottom of the page to read them from the top of the article (or use Hypothes.is to see them in context,there’s no way to link to the overview directly for non-users I think).

I re-installed the plugin in Obsidian, and will work with it some more. Here’s hoping some of the original glitches no longer occur.

We had a strong personal motivation for this project: we often find ourselves stuck in our own creative work. Latticework’s links might make you think of citations and primary sources—tools for finding the truth in a rigorous research process. But our work on Latticework was mostly driven by the problems of getting emotionally stuck, of feeling disconnected from our framing of the project or our work on it.

I topped 1000 annotations in Hypothesis today. That is a year and 9 months after reaching 100 after the first month, or about 45 per month in total. Almost all of them are public annotations (97%).

While I do use it regularly, I don’t use it daily or at high volume. Annotations are automatically added to my local notes through the Hypothesis API, which is where I continue working on them. About the same number of annotations I make directly from my browser to my notes using a markdown webclipper, mostly when I save an entire article. Any annotations of PDFs I do in Zotero, and then there’s the e-book and paper book annotations. So at most a quarter of my annotations is in Hypothes.is.

In my annotations I have become accustomed to referencing existing notes (I have a little hotkey that lets me search and then paste a note title as markdown link in the annotation), using tags, and adding to-do’s that are picked up by my to-do lists. Things I started doing in the first month, like adding webarchive urls as page note, I still routinely do. All good reduction of friction I find.

I made it possible to post a first page annotation to Hypothes.is directly from my feed reader a year ago. While in theory that is very useful, in practice I’ve used it sparingly. Mostly because I have been spending less time inside my feed reader I think.

Many annotations are just basically bookmarking an article with a first remark for curation and being able to find it back in my own terms. While I do return to some of those for more extensive annotation, that is not often. Partly because I may do that in my local notes, partly because as always you encounter more than you can process. I do regularly re-find my annotations in my notes when searching, which is useful, and that sometimes results in revisiting an article for further annotation.

There is some performance effect involved in public annotation I suspect. I annotate mostly in English and am always aware others may read that. Especially criticism brings that awareness. It makes it feel like a form of blogging, but with an even smaller audience than my blog’s.

The social effect I experience of using Hypothes.is is very small. I’m not involved in annotating groups, which undoubtedly would feel different. I have had some conversation resulting from annotation however, which is always fun.

While I am enthusiastic about Hypothes.is as a tool, it hasn’t become a central tool, nor the primary ‘place’ for annotating things. I wonder if that would be different if I was more capable in interacting more with the API (e.g. to send changes or other annotations sources to H.), or if I could run a personal instance of it and federate that.

I started using Hypothes.is after the summer of 2022 because of reading the book Annotation by Kalir and Garcia in the spring of 2022 (although my Hypothesis account already existed).
My perception of annotations has permanently changed because of reading that book. It is now a much more everyday occurrence and practice within my sense making, not just for academic articles or books, and can take different shapes and forms. Just that most of that takes place outside of Hypothes.is.

The innovations in personal knowledge management are sparse and far between, is a phrase that has circulated in my mind the past three weeks. Chris Aldrich in his online presentation at PKM Summit expressed that notion while taking us through an interesting timeline of personal knowledge management related practices. As his talk followed that timeline, it didn’t highlight the key innovations as an overview in itself. I had arranged the session because I wanted to raise awareness that many practices we now associate with 20th century or digital origins, in fact are much older. It’s just that we tend to forget we’re standing on many shoulders, taking a recent highly visible example as original source and our historic horizon. Increased historic awareness is however something different than stating there has been hardly any notable innovation in this space over the course of millennia. Because that leads to things like asking what then are the current adjacent possible innovations, what branches might be developed further?

It all starts with a question I have for Chris however: What are the innovations you were thinking of when you said that?

Below I list some of the things that I think are real innovations in the context of personal knowledge management, in roughly chronological order. This is a list from the top of my head and notes, plus some very brief search on whether what I regard as origin of a practice is actually a more recent incarnation. I have left out most of the things regarding oral traditions, as it is not the context of my practices.

  • Narration, prehistory
  • Songlines, prehistory
  • Writing, ending prehistory
  • Annotation, classical antiquity
  • Loci method, memory palaces, classical antiquity
  • Argument analysis, classical antiquity
  • Tagging, classical antiquity
  • Concept mapping, 3rd century
  • Indexes, Middle Ages
  • Letterpress printing, renaissance
  • Paper notebooks, renaissance
  • Commonplace books, renaissance
  • Singular snippets / slips, 16th century
  • Stammbuch/Album Amicorum, 16th century
  • Pre-printed notebooks, 19th century
  • Argument mapping, 19th century
  • Standard sized index cards, 19th century
  • Sociograms/social graphs, early 20th century
  • Linking, 20th century (predigital and digital)
  • Knowledge graphs, late 20th century (1980s)
  • Digital full text search, late 20th century

Chris, what would be your list of key innovations?
