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.

Given his experience in the space, the work of creating a second index (card index/zettelkasten), marks an important change or shift in perspective.

This may shed light on Niklas Luhmann's practices between ZKI and ZKII. What were the important differences between the two? Presumably closer focus was important for ZKII.

In my experience, alternating alphanumeric codes give you the "gist" of the original context. Purely with reference to my rough outline, my notecard "3516/b" implies psychology (3XXX), cognition (35XX), and memory (351X). Even the single slash implies a level of abstraction and/or specificity.

But it's not enough because it runs the risk of locking you in. Forward links on the card (or forward links to the card!) offer comparable if not competitive recontextualization, which is most likely what Luhmann means by "multiple storage".

Caution: My note here has some significant missing context which results from significant additional research.

The primary issue with analog slip boxes, particularly in academic research of Luhmann's day, was one of multiple storage. No one else I'm aware of prior to his time used Luhmann's filing scheme (and very few after until about 2013). Instead most filed multiple copies of their notes under category headings like "psychology", "cognition", and "memory" (to use your example) so that those ideas would be readily available when they came to work on their ideas relating to cognition, for example. This involved a tremendous amount of copying work. (For reference, see Heyde, Johannes Erich. Technik des wissenschaftlichen Arbeitens: zeitgemässe Mittel und Verfahrungsweisen. Junker und Dünnhaupt, 1931. which is the handbook which Luhmann used to scaffold his method.) It was this copying and filing under multiple categories which was commonly referred to as multiple storage. Many academics got around it by hiring assistants or secretaries who would do this duplicative work and filing on their behalf; Luhmann didn't have this additional help and it may have been a portion of the pressure for the evolution of his method.

Instead Luhmann used branching and cross-indexing his ideas along with regular use and familiarity of the space within his boxes. While his zettelkasten may seem on the surface to be done by category, the way you suggest, it definitely is not. Some of this appearance is suggested by editorial decisions made by the curators of his digital archive and, in larger part, by Scott Scheper who (sadly in my opinion) recommends using the Academic Outline of Disciplines as top level categories a practice which heavily belies some of what Luhmann was doing. While Luhmann was inspired by the Dewey Decimal System, he wasn't using the parts of it that equated numbers with topics, in part because he didn't need to and it would have been counterproductive to his ultimate method—specifically causing him to deal with multiple storage. Modern (digital) database theory and practice allows some note takers an easier way around this problem.

Warburg kept zettelkasten both at his library as well as at his private home. A photograph from his home shows boxes ready to hand on the right side side of his desk and another shows boxes lined up on the left hand side.

Correcting a text within a digital archive or database allows the change to propagate to all portions of the collection compared with a physical card index which has the hurdle of multiple storage and requires manual changes on all of the associated copies.

This sort of affordance can be seen in more modern note taking tools like Obsidian which does this sort of work with global search and replace of double bracketed words which change everywhere in the collection.

Seems like from a historical perspective hierarchical databases were more prevalent in the 1960s and relational databases didn't exist until the 1970s. (check references for this historically)

Of course one must consider that within a card index or zettelkasten the ideas of both could have co-existed in essence even if they weren't named as such. Some of the business use cases as early as 1903 (earlier?) would have shown the idea of multiple storage and relational database usage. Beatrice Webb's usage of her notes in a database-like way may have indicated this as well.

9/8b2 "Multiple storage" as a necessity of<br /> storage of complex (complex<br /> evaluating) information.

Fascinating to see the English phrase "multiple storage" pop up in Luhmann's ZKII section on Zettelkasten.

This note is undated, though being in ZKII likely occurred more than a decade after he'd started his practice. One must wonder where he pulled the source for the English phrase rather than using a German one? Does the idea appear in Heyde? It certainly would have been an emerging question within systems theory and potentially computer science ideas which Luhmann would have had access to.

Most veteran note takers will advise against importing old notes into a new digital space for the extra amount of administrative overhead and refactoring it can create.

Often old notes may be: - well assimilated into your memory already - poorly sourced or require lots of work and refactoring to use or reuse them - become a time suck trying to make them "perfect"

Better advice is potentially pull them into your system in a different spot so they're searchable and potentially linkable/usable as you need them. If this seems like excessive work, and it very well may be, then just pull in individual notes as you need or remember them.

With any luck the old notes are easily searchable/findable in whichever old system they happen to be in, so they're still accessible.

I'll note here the conflicting definitions of multiple storage in my tags to mean: - storing a single note under multiple subject headings or index terms - storing notes in various different (uncentralized locations), so having multiple different zettelkasten at home/office, storing some notes in social media locations, in various notebooks, etc. This means you have to search across multiple different interfaces to find the thing you're looking at.

I should create a new term to distinguish these two, but for now they're reasonably different within their own contexts that it's not a big problem unless one or the other scales.
