inspired by, but definitely not take from as not in evidence

Many people have "daily notes" and "project notes" in what they consider to be their zettelkasten workflow. These can be thought of as subcategories of reference notes (aka literature notes, bibliographic notes). The references in these cases are simply different sorts of material than one would traditionally include in this category. Instead of indexing the ideas within a book or journal article, you're indexing what happened to you on a particular day (daily notes) or indexing ideas or progress on a particular project (project notes). Because they're different enough in type and form, you might keep them in their own "departments" (aka folders) within your system just the same way that with enough material one might break out their reference notes to separate books from newspapers, journal articles, or lectures.

In general form and function they're all broadly serving the same functionality and acting as a ratchet and pawl on the information that is being collected. They capture context; they serve as reminder. The fact that some may be used less or referred to less frequently doesn't make them necessarily less important

Miles, 1905 uses an arrow symbol with a hash on it to indicate a "connecting link between two Sentences or Paragraphs, etc."

It's certainly an early example of what we would now consider a hyperlink. It actively uses a "pointer" in it's incarnation.

Are there earlier examples of these sorts of idea links in the historical record? Surely there were circles and arrows on a contiguous page, but what about links from one place to separate places (possibly using page numbers?) Indexing methods from 11/12C certainly acted as explicit sorts of pointers.

I very much like this idea! I have years of journals that I sometimes peruse, and have lamented that so many "good ideas" live in there, but I never use them, or much see them. This has me wondering if I can incorporate them into my zettelkasten.

Adler is indexing not just the topics, but he's doing it in the order of their temporal appearance in the book as they're used (presumably to make arguments). This then also becomes an outline of these arguments.

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.

There are likely other metadata he may be missing here: - in particular dates/times/time periods which may be useful for the historians. - others? - general forms of useful metadata from a database perspective?

I'm reminded of Dennis Duncan's (2022) description of a book which indexed photos as a means of reaching those who were illiterate.

While Kaiser's definition of literature presumes letters and writing, his use of it doesn't narrow it down to require literacy, it speaks only of observations and language.

Similarly his use of "records" doesn't need to only to require writing.

As such, the description here of recording information, while applicable to literate cultures, leaves plenty of room for oral cultures who use similar systems to do the same thing.

Songlines and related mnemonics are certainly means of indexing information.

For Kaiser, his "intelligence department" has three broad functions: summarizing, indexing, and filing.

Catchwords (broad or even narrow topics) can be useful, but one should expand beyond these short words to full phrases or even sentences/paragraphs which contain atomic (or perhaps molecular) ideas that can be linked.

We could reframe the atomic as simple catchwords, and make molecular ideas combinations of these smaller atoms which form larger and fuller thoughts which can be linked and remixed with others.

Dennis Duncan (2022) touches on this in his book on Indexing when he looks at indexes which contained portions of their fuller text which were later removed and thereby collapsing context. Having these pieces added back in gave a fuller picture of ideas within an index. Connect this idea with his historical examples.

Great indexes go beyond the catchword to incorporate full ideas with additional context. To some extent this is what Luhmann was doing at larger scale compared to his commonplacing brethren who were operating far more closely to the catchword (tag) level. (Fortunately they held the context in their heads and were thus able to overcome some of the otherwise inherent problems.)

The development of all of this historically seems to follow the principle of small pieces loosely joined.

Repetition of the idea that indexing brings ideas together.

https://hypothes.is/a/psgmlu7qEe6MIiNGfuzB2A

Luhmann's topical index was a form of a central register as he concatenated words on cards rather than having a separate card for each word.

Kaiser lays out an alphanumeric system for indexing materials using letters, numbers, and even dates and importantly suggests a 1-1 and onto relationship (though not in these terms) to prevent confusion.

Compare with Niklas Luhmann's system.

Indexing the world into a commonplace book, zettelkasten, or other means can create new perspectives on the world in which we live. It thereby helps to prevent the sorts of cognitive bias which we might otherwise fall trap to.

This example of Homes indexing crime gives him a dramatically different perspective on crime in the countryside to Watson who only sees the beauty in the story of "The Adventure of the Copper Beeches."

It's no wonder that Mortimer J. Adler was able to write such a deep analysis of reading in How to Read a Book after having spent so much time indexing the ideas behind The Great Books of the Western World.

Indexing requires a solid inspectional read at minimum, but will often go deeper into contexts which require at least some analytical reading. To produce the Syntopicon, one must go even further into analytical reading to provide the proper indexing of ideas so that they may be sub-categorized and used for deeper analysis for things such as comparison and contrast of those ideas.

context: the simultaneous invention of two different methods of indexing: subject indexes and concordances

Robert Cotton's library had busts of Roman emperors atop his shelves, and he used their names as part of his indexing system to be able to associate books' locations to make them findable.

Keyword search was definitely available in Luhmann's lifetime. Here's the link to the digitized version of Luhmann's keyword index: https://niklas-luhmann-archiv.de/bestand/zettelkasten/zettel/ZK_2_SW1_001_V. Versions of this sort of indexing go back at least to John Locke's method for indexing commonplace books in 1685 (in French) and 1706 (in English). See: https://archive.org/details/13925922180LockeCommonplaceBook/mode/2up for the 1706 version. In a zettelkasten context, instead of indexing page numbers, one simply numbers their index cards and the method works exactly the same. (One could also think of it as creating a library card catalog for one's ideas instead of their books—again, using a personalized numbering system instead of the standardized Dewey Decimal System which is used for books.)

In paper versions, the numbers serve two purposes:

• Allowing the ideas to be indexed and searched for and found again. Full text search in digital contexts may be easier in some instances, but these sorts of searches may not scale well over thousands of notes and may return hundreds of results which need to be looked through to find the correct one. As a result, even good indexing in digital can pay off well in the long run.
• Placing similar ideas next to each other (when filed using numbers) allows areas of interest to build up in one's note collection. This also creates what one might call "soft links" between ideas (versus more direct, hard links using [[WikiLinks]] or explicit links to specific numbered cards). These neighborhoods of ideas eventually build up to something interesting in aggregation. Without these sorts of (decimal or alpha-numeric) numbers, it's more difficult to create this affordance in digital applications (and one has to be more vigilant for orphaned notes). One can use tags or category names in Obsidian along with the graph view to approximate some of this affordance, but it requires more work on the part of the user. Prepending sortable numbers onto the titles of notes can allow these neighborhoods to be more visible in the sidebar folder view found in many digital tools.

Some will suggest or use some sort of date/timestamp number as a unique identifier, but doing this generally has little or no value and most digital systems will automatically add date/time creation and modification timestamps to notes anyway if those are of interest or value.

More details: https://boffosocko.com/2022/10/27/thoughts-on-zettelkasten-numbering-systems/

Knowing these potential affordances, try things out for a while to see how they work for you and then decide to continue or change your practice to suit your own needs.

reply to u/JonasanOniem at https://www.reddit.com/r/Zettelkasten/comments/16ss0yu/linking_new_notes/

This sort of practice is harder when you start out in most digital apps because there is usually no sense of "closeness" of ideas in digital the way that is implied by physical proximity (or "neighborhood") found in physical cards sitting right next to or around each other. As a result, you have to create more explicit links or rely on using tags (or indexing) when you start. I've not gotten deep into the UI of Zettlr, but some applications allow the numbering (and the way numbered ideas are sorted in the user interface) to allow this affordance by creating a visual sense of proximity for you. As you accumulate more notes, it becomes easier and you can rely less on tags and more on direct links. Eventually you may come to dislike broad categories/tags and prefer direct links from one idea to another as the most explicit tag you could give a note . If you're following a more strict Luhmann-artig practice, you'll find yourself indexing a lot at the beginning, but as you link new ideas to old, you don't need to index (tag) things as heavily because the index points to a card which is directly linked to something in the neighborhood of where you're looking. Over time and through use, you'll come to recognize your neighborhoods and the individual "houses" where the ideas you're working with all live. As an example, Luhmann spent his life working in sociology, but you'll only find a few links from his keyword register/subject index to "sociology" (and this is a good thing, otherwise he'd have had 90,000+ listings there and the index entry for sociology would have been utterly useless.)

Still, given all this, perhaps as taurusnoises suggests, concrete examples may help more, particularly if you're having any issues with the terminology/concepts or how the specific application affordances are being presented.

https://www.youtube.com/watch?v=1iRzF_ZAdUI

Scott Sheper demonstrates one of the lowest forms of zettelkasten: simply indexing an idea from a book into one's index. This includes skipping the step of excerpting the idea into it's own card.

He describes it as zettelkasten knowledge building for busy people. It's definitely a hard turn from his all-in Luhmann-esque method.

In the end it comes down to where one puts in the work. Saving the work of having done some reading for a small idea one may tangentially reference later is most of the distance, but he's still going to have to do more work later to use the idea.

reply to m_t_rv_s__n/ at https://www.reddit.com/r/Zettelkasten/comments/164n6qg/is_this_overkill/

First, your system is historically far more traditional than Luhmann's more specific practice. See: https://boffosocko.com/2022/10/22/the-two-definitions-of-zettelkasten/

If you're taking all the notes/highlights from a particular book and keeping them in a single file, then it may be far quicker and more productive to do some high level tagging on the entire book/file itself and then relying on and using basic text search to find particular passages you might use at a later date.

Spending time reviewing over all of your notes and tagging/indexing them individually may be beneficial for some basic review work. But this should be balanced out with your long term needs. If your area is "sociology", for example, and you tag every single idea related to the topic of sociology with #sociology, then it will cease to have any value you to you when you search for it and find thousands of disconnected notes you will need to sift through. Compare this with Luhmann's ZK which only had a few index entries under "sociology". A better long term productive practice, and one which Luhmann used, is indexing one or two key words when he started in a new area and then "tagging" each new idea in that branch or train of though with links to other neighboring ideas. If you forget a particular note, you can search your index for a keyword and know you'll find that idea you need somewhere nearby. Scanning through the neighborhood of notes you find will provide a useful reminder of what you'd been working on and allow you to continue your work in that space or link new things as appropriate.

If it helps to reframe the long term scaling problem of over-tagging, think of a link from one idea to another as the most specific tag you can put on an idea. To put this important idea into context, if you do a Google search for "tagging" you'll find 240,000,000 results! If you do a search for the entirety of the first sentence in this paragraph, you'll likely only find one very good and very specific result, and the things which are linked to it are going to have tremendous specific value to you by comparison.

Perhaps the better portions of your time while reviewing notes would be taking the 150 highlights and finding the three to five most important, useful, and (importantly) reusable ones to write out in your own words and begin expanding upon and linking? These are the excerpts you'll want to spend more time on and tag/index for future use rather than the other hundreds. Over time, you may eventually realize that the hundreds are far less useful than the handful (in management spaces this philosophy is known as the Pareto principle), so spending a lot of make work time on them is less beneficial for whatever end goals you may have. (The make work portions are often the number one reason I see people abandoning these practices because they feel overwhelmed working on raw administrivia instead of building something useful and interesting to themselves.) Naturally though, you'll still have those hundreds sitting around in a file if you need to search, review, or use them. You won't have lost them by not working on them, but more importantly you'll have gained loads of extra time to work on the more important pieces. You should notice that the time you save and the value you create will compound over time.

And as ever, play around with these to see if they work for you and your specific needs. Some may be good and others bad—it will depend on your needs and your goals. Practice, experiment, have fun.

reply to IvanCyb at https://www.reddit.com/r/antinet/comments/1587onp/comment/jt8zbu4/?utm_source=reddit&utm_medium=web2x&context=3 Asking broadly about indexing methods in zettelkasten

When you begin you'll find yourself creating lots of index entries to start, in part because you have none, but you'll find with time that you need to do less and less because index entries already exist for most of what you would add. More importantly most of the entries you might consider duplicating are likely to be very near cards that already have those index entries.

As an example if you have twenty cards on cultural anthropology, the first one will be indexed with "cultural anthropology" to give you a pointer of where to start. Then when you need to add a new card to that section, you'll look up "cultural anthropology" and skim through what you've got to find the closest related card and place it. You likely won't need to create a new index entry for it at all.

But for argument's sake, let's say you intend to do some work at the intersection of "cultural anthropology" and "writing" and this card is also about "writing". Then you might want to add an index entry for "writing" from which you'll branch off in the future. This will tend to keep your index very sparse. As an example you can look at Niklas Luhmann's digitized collection to notice that he spent his career in the area of "sociology" but there are only just a few pointers from his index into his collection under that keyword. If he had tagged every single card related to "sociology" as "sociology" in his index, the index entry for it would have been wholly unusable in just a few months. Broadly speaking his entire zettelkasten is about sociology, so you need to delve a few layers in and see which subtopics, sub-subtopics, sub-sub-subtopics, etc. exist. As you go deeper into specific topics you'll notice that you branch down and out into more specific subareas as you begin to cover all the bases within that topic. If you like, for fun, you can see this happening in my digital zettelkasten on the topic of "zettelkasten" at https://hypothes.is/users/chrisaldrich?q=tag%3A%22zettelkasten%22. The tool only shows the top 50 tags for that subject in the side bar, but you can slowly dig down into subtopics to see what they look like and a bit of how they begin to overlap.

Incidentally, this is one of the problems with those who tag everything with top level topic headings in digital contexts—you do a search for something important and find so much that it becomes a useless task to try to sift through it all. As a result, users need better tools to give them the ability to do more fine-grained searching, filtering, and methods of discovery.

Connecting a Zettelkasten to a Commonplace Book

Interesting to see Scott trying this... I'm sure I've seen it before in a setting like this, but its obviously been done in the commonplace space by itself.

@cristinadias7 If you're interested in the overlap of zettelkasten and art or even zettelkasten for art, I've got a small collection available digitally if you think it would be useful/helpful.

Some artworks are difficult to index on physical cards because of their physical nature, so if it helps and you don't have pictures available to file away, you can index their storage locations the way libraries would index "realia" and keep your notes on them there. Twyla Tharpe kept actual objects in larger boxes by categories which is another fascinating way of doing things.

The method used for indexing the Wörterbuch der ägyptischen Sprache and the Thesaurus Linguae Latinae is now generally known as a key word in context (KWIC) index.

This is a major drawback to this method and the affordance of sparse indexing using Luhmann's method.

Do folgezettel in combination with an index help to prevent over-indexing behaviors? Or the scaling problem of categorization in a personal knowledge management space?

Where do subject headings within a zettelkasten dovetail with the index? Where do they help relieve the idea of heavy indexing or tagging? How are the neighborhoods of ideas involved in keeping a sense of closeness while still allowing density of ideas and information?

Having digital search views into small portions of neighborhoods like gxabbo suggested can be a fantastic affordance. see: https://hypothes.is/a/W2vqGLYxEe2qredYNyNu1A

For example, consider an anthropology student who intends to spend a lifetime in the subject and its many sub-areas. If they begin smartly tagging things with anthropology as they start, eventually the value of the category, any tags, or ideas within their index will eventually grow without bound to the point that the meaning or value as a search affordance within their zettelkasten (digital or analog) will be utterly useless. Let's say they fix part of the issue by sub-categorizing pieces into cultural anthropology, biological anthropology, linguistic anthropology, archaeology, etc. This problem is fine while they're in undergraduate or graduate school for a bit, but eventually as they specialize, these areas too will become overwhelming in terms of search and the search results. This problem can continue ad-infinitum for areas and sub areas. So how can one solve it?

Is a living and concatenating index the solution? The index can have anthropology with sub-areas listed with pointers to the beginnings of threads of thought in these areas which will eventually create neighborhoods of these related ideas.

The solution is far easier when the ideas are done top-down after-the-fact like in the Dewey Decimal System when the broad areas are preknown and pre-delineated. But in a Luhmann-esque zettelkasten, things grow from the bottom up and thus present different difficulties from a scaling up perspective.

How do we classify first, second, and third order effects which emerge out of the complexity of a zettelkasten? - Sparse indexing can be a useful long term affordance in the second or third order space. - Combinatorial creativity and ideas of serendipity emerge out of at least the third order. - Using ZK for writing is a second order affordance - Storage is a first order affordance - Memory is a first order affordance (related to storage) - Productivity is a second+ order (because solely spending the time to save and store ideas is a drag at the first order and doesn't show value until retrieval at a later date). - Poor organization can be non-affordance or deterrent which results in a scrap heap - lack of a reason why can be a non-affordance or deterrence as well - cross reference this list and continue on with other pieces and affordances

https://www.reddit.com/r/antinet/comments/10xls6m/does_anyone_ever_get_frustrated/

This idea is quite interesting in the sense that categorization is limiting. Defining is limitation

https://iiif.lib.harvard.edu/manifests/view/drs:13925922

A specific reference to the commonplace book tradition and in particular the practice of segmenting note books into pre-defined segments with particular topic headings. This practice described here also ignores the practice of keeping an index (either in a separate notebook or in the front/back of the notebook as was more common after John Locke's treatise)

Watch closely to see how Allosso's description of an index comes to the advice of John Locke versus the practice of Niklas Luhmann.

Alternately, is it closer to a commonplace indexing system or a shallowly linked, but still complex zettelkasten indexing system?

In shared digital systems, I still suspect that densely indexed notes will have more communal value.

Come be a part of my sales funnel!!!

ugh... This should generally be sacrilege, but it's even worse when having a solid index (which is roughly the purpose that tags support) is an important part of any commonplace book, especially since John Locke, which a resource Forte has cited elsewhere in his book.

Coming back to the beginning of this section. He talks about tags, solely after-the-fact instead of when taking notes on the fly. While it might seem that he would have been using tags as subject headings in a traditional commonplace book, he really isn't. This is a significant departure from the historical method!! It's also ill advised not to be either tagging/categorizing as one goes along to make searching and linking things together dramatically easier.

How has he missed the power of this from the start?! This is really a massive flaw in his method from my perspective, particularly as he quotes John Locke's work on the topic.

Did I maybe miss some of this in earlier sections when he quoted John Locke? Double check, just in case, but this is certainly the section of the book to discuss using these ideas!

Locke's method is certainly a compact one and is specifically designed for notebooks of several hundred pages where you're slowly growing the index as you go within a limited and usually predetermined amount of space. If you're using an index card or digital system where space isn't an issue, then that specific method may not be as ideal. Whichever option you ultimately choose, it's certainly incredibly valuable and worthwhile to have an index of some sort.

For those into specifics, here's some detail about creating an index using Hypothes.is data in Obsidian: https://boffosocko.com/2022/05/20/creating-a-commonplace-book-or-zettelkasten-index-from-hypothes-is-tags/ and here's some detail for how I did it for a website built on WordPress: https://boffosocko.com/2021/09/04/an-index-for-my-digital-commonplace-book/

I'm curious to see how others do this in their tool sets, particularly in ways that remove some of the tedium.

https://www.revolutionaryplayers.org.uk/the-scope-and-nature-of-darwins-commonplace-book/

Erasmus Darwin's commonplace book

It is one of the version(s?) published by John Bell based on John Locke's method and is a quarto volume bound in vellum with about 300 sheets of fine paper.

Blank pages 1 to 160 were numbered and filled by Darwin in his own hand with 136 entries. The book was started in 1776 and continued until 1787. Presumably Darwin had a previous commonplace book, but it has not been found and this version doesn't have any experiments prior to 1776, though there are indications that some material has been transferred from another source.

The book contains material on medical records, scientific matters, mechanical and industrial improvements, and inventions.

The provenance of Erasmus Darwin's seems to have it pass through is widow Elizabeth who added some family history to it. It passed through to her son and other descendants who added entries primarily of family related topics. Leonard Darwin (1850-1943), the last surviving son of Charles Darwin gave it to Down House, Kent from whence it was loaned to Erasmus Darwin House in 1999.

The addressing system that many digital note taking systems offer is reminiscent of Luhmann's paper system where it served a particular use. Many might ask themselves if they really need this functionality in digital contexts where text search and other affordances can be more directly useful.

Frequently missed by many, perhaps because they're befuddled by the complex branching numbering system which gets more publicity, Luhmann's paper-based system had a highly useful and simple subject heading index (see: https://niklas-luhmann-archiv.de/bestand/zettelkasten/zettel/ZK_2_SW1_001_V, for example) which can be replicated using either #tags or [[wikilinks]] within tools like Obsidian. Of course having an index doesn't preclude the incredible usefulness of directly linking one idea to potentially multiple others in some branching tree-like or network structure.

Note that one highly valuable feature of Luhmann's paper version was that the totality of cards were linked to a minimum of at least one other card by the default that they were placed into the file itself. Those putting notes into Obsidian often place them into their system as singlet, un-linked notes as a default, and this can lead to problems down the road. However this can be mitigated by utilizing topical or subject headings on individual cards which allows for searching on a heading and then cross-linking individual ideas as appropriate.

As an example, because two cards may be tagged with "archaeology" doesn't necessarily mean they're closely related as ideas. This tends to decrease in likelihood if one is an archaeologist and a large proportion of cards might contain that tag, but will simultaneously create more value over time as generic tags increase in number but the specific ideas cross link in small numbers. Similarly as one delves more deeply into archaeology, one will also come up with more granular and useful sub-tags (like Zooarcheology, Paleobotany, Archeopedology, Forensic Archeology, Archeoastronomy, Geoarcheology, etc.) as their knowledge in sub areas increases.

Concretely, one might expect that the subject heading "sociology" would be nearly useless to Luhmann as that was the overarching topic of both of his zettelkästen (I & II), whereas "Autonomie" was much more specific and useful for cross linking a smaller handful of potentially related ideas in the future.

Looking beyond Luhmann can be highly helpful in designing and using one's own system. I'd recommend taking a look at John Locke's work on indexing (1685) (https://publicdomainreview.org/collection/john-lockes-method-for-common-place-books-1685 is an interesting source, though you're obviously applying it to (digital) cards and not a notebook) or Ross Ashby's hybrid notebook/index card system which is also available online (http://www.rossashby.info/journal/index.html) as an example.

Another helpful tip some are sure to appreciate in systems that have an auto-complete function is simply starting to write a wikilink with various related subject heading words that may appear within your system. You'll then be presented with potential options of things to link to serendipitously that you may not have otherwise considered. Within a digital zettelkasten, the popularly used DYAC (Damn You Auto Complete) may turn into Bless You Auto Complete.

Most people born since the advent of the filing cabinet and the computer have spent a lifetime using a hierarchical folder-based mental model for their knowledge. For greater value and efficiency one needs to get away from this model and move toward linking individual ideas together in ways that they can more easily be re-used.

To accomplish this many people use an index-based method that uses topical or subject headings which can be useful. However after even a few years of utilizing a generic tag (science for example) it may become overwhelmed and generally useless in a broad search. Even switching to narrower sub-headings (physics, biology, chemistry) may show the same effect. As a result one will increasingly need to spend time and effort to maintain and work at this sort of taxonomical system.

The better option is to directly link related ideas to each other. Each atomic idea will have a much more limited set of links to other ideas which will create a much more valuable set of interlinks for later use. Limiting your links at this level will be incredibly more useful over time.

One of the biggest benefits of the physical system used by Niklas Luhmann was that each card was required to be placed next to at least one card in a branching tree of knowledge (or a whole new branch had to be created.) Though he often noted links to other atomic ideas there was at least a minimum link of one on every idea in the system.

For those who have difficulty deciding where to place a new idea within their system, it can certainly be helpful to add a few broad keywords of the type one might put into an index. This may help you in linking your individual ideas as you can do a search of one or more of your keywords to narrow down the existing ones within your collection. This may help you link your new idea to one or more of those already in your system. This method may be even more useful and helpful for those who are starting out and have fewer than 500-1000 notes in their system and have even less to link their new atomic ideas to.

For those who have graphical systems, it may be helpful to look for one or two individual "tags" in a graph structure to visually see the number of first degree notes that link to them as a means of creating links between atomic ideas.

To have a better idea of a hierarchy of value within these ideas, it may help to have some names and delineate this hierarchy of potential links. Perhaps we might borrow some well ideas from library and information science to guide us? There's a system in library science that uses a hierarchical set up using the phrases: "broader terms", "narrower terms", "related terms", and "used for" (think alias or also known as) for cataloging books and related materials.

We might try using tags or index-like links in each of these levels to become more specific, but let's append "connected atomic ideas" to the bottom of the list.

Here's an example:

• broader terms (BT): [[physics]]
• narrower terms (NT): [[mechanics]], [[dynamics]]
• related terms (RT): [[acceleration]], [[velocity]]
• used for (UF) or aliases:
• connected atomic ideas: [[force = mass * acceleration]], [[$$v^2=v_0^2​+2aΔx$$]]

Chances are that within a particular text, one's notes may connect and interrelate to each other quite easily, but it's important to also link those ideas to other ideas that are already in your pre-existing body of knowledge.

Brief discussion of indexing systems for commonplace books. Locke's system is mentioned. Another person uses a clunky system at the bottom of pages to create threaded links.

Intriguingly, one person mentions visiting theirs often enough that they remember where things are. (spaced repetition with a bit of method of loci going on here)

I remember also seeing this as an indexing system for index cards in 2007. https://www.flickr.com/photos/hawkexpress/sets/72157594200490122/

It's not too dissimilar a pattern from the early 20th century edge-notched cards which were used to make sorting collections easier. https://en.wikipedia.org/wiki/Edge-notched_card Of course doing this for a notebook isn't going to work as easily.

Example of a edge-based taxonomy system for index cards.

I've used something like this in a textbook before while also using different colored pens to help differentiate a larger taxonomy. I found it to be better for a smaller custom cpb that only had a narrow section of topics. In my larger, multi-volume commonplace, I have a separate volume that serves as an index and uses a method similar to John Locke's, though larger in scope and shape. Sadly in this case, the index would be much too large (with too many entries) to make the high five method practicable.

Originally suggested by Alan Levine. Some interesting specific examples here, but I've been aware of the concept for a while.

I've also articulated this point, but in a negative context. This piece speaks of actor-indexed content in a positive light. I maintain that actor-indexed content is on the whole negative. It's a direct and indirect cause of the familiar social media ills and has wide-reaching privacy implications, which is bad in and of itself, but especially so when you realize that this in turn leads to a chilling effect where people simply opt not to play because it's the only remedy.

We'd do well socially to abandon the "game-changing" practice of indexing based on actor and return to topic-based indexing, which better matches the physical world.

Interesting to see that Jonathan Edwards cross referenced his commonplace book to his bible as well.

Explore why this is so from an information theoretic perspective. Is it true?

Broad recycle of Tim Bray's article https://www.tbray.org/ongoing/When/201x/2018/01/15/Google-is-losing-its-memory with an example of the same effect for their site.

DuckDuckGo has a better index that doesn't prioritize for "right now" or currency.

Indices are simply a physical manifestation of metadata upon which we built a rudimentary search algorithm.

Might be an interesting source to read.

Also feels in form a bit like the combinatorial method of Raymond Llull, but without as much mixing.

Bush emphasises the importance of retrieval in the storage of information. He talks about technical limitations, but in this paragraph he stresses that retrieval is made more difficult by the "artificiality of systems of indexing", in other words, our default file-cabinet metaphor for storing information.

Information in such a hierarchical architecture is found by descending down into the hierarchy, and back up again. Moreover, the information we're looking for can only be in one place at a time (unless we introduce duplicates).

Having found our item of interest, we need to ascend back up the hierarchy to make our next descent.

Saya masih setuju sampai sini. Untuk paragraf kedua, di sinilah peran preprint (atau versi pra cetak). Silahkan kirim ke jurnal manapun, tapi jangan lupa anda juga punya hak untuk mempublikasikannya seawal mungkin, tanpa ada batasan peninjauan sejawat. Manfaatkan hak itu.

Aktivitas mengunggah preprint atau dokumen apapun ke media yang diindeks oleh mesin pencari (misal Google Scholar) akan menyebabkan seolah karya anda membengkak. Jangan khawatir. Kalau memang kegiatan anda banyak, ya wajar banyak dokumen yang dihasilkan. Mesin pencari atau pengindeks tugasnya menemukan dokumen itu saat kawan atau kolega anda mencari informasi. Itu saja tugas. Ia tidak bertugas memberikan skor atau nilai kepada dokumen anda. Jadi untuk apa memprotes seseorang yang terlalu banyak mengunggah dokumen daring. Lebih baik instrumen pengindeksnya saja yang dimatikan. Toh bukan itu tujuannya dibuat awalnya.

Wodurch ist diese hierarchische Feldsuche möglich? bzw. Wie habt Ihr die hierarchischen JSON-Daten indexiert? So weit ich weiß, sind in den meisten Fällen die Daten in einem Lucene basierten Index flach, das scheint bei Euch nicht der Fall zu sein. Mich würden die Details der Indexierung interessieren, die die hierarchische Feldsuche ermöglichen. Dies ist möglicherweise auch für viele Anwendungsfälle in den DH interessant, wo hierarchische TEI-Strukturen vorhanden sind.

Going to work is analogous to passive indexing.

C’était long, en 2002! Où en est la BnF, aujourd’hui? D’une certaine façon, ce résumé semble prédire la venue des données, la fédération des catalogues, etc. Pourtant, il semble demeurer de nombreux obstacles, malgré tout ce temps. Et si on pouvait annoter le Web directement?

I would agree that "the problem of indexing and finding relevant information is tougher today than ever before" ... and especially "on one's own hard disk".

Vannevar Bush recognized the problem of artificial systems of indexing long before McIlroy pulled this page from his typewriter in 1964, and here we are 50 years later using the same kind of filesystem indexing systems and wondering why it's harder than ever to find information on our own hard drives.

With the advent of Google Docs we're finally moving away from the archaic indexing mentioned here. The filesystem metaphor was simple and dominated how everyone manages their data-- which extended into how we developed web content, as well.

The declaration that Hierarchical File Systems are Dead has led to better systems of tagging and search, but we're still far from where we need to be since there is still a heavy focus on the document as a whole instead of also the content within the document.

The linearity of printed books is even more treacherously entrenched in our minds than the classification systems used by libraries to store those books.

One day maybe we'll liberate every piece of content from every layer of its concentric cages: artificial systems of indexing, books, web pages, paragraphs, even sentences and words themselves. Only then will we be able to re-dress those thoughts automatically into those familiar and comforting forms that keep our thoughts caged.

The essential feature of the memex is its ability of association; tying two items together.
