I now have definitive written proof of a numeric indexing system (delineated in a popular textbook for secretaries, and published by a company which did significant business in Germany) from the mid-1920s with increasingly more detail into the 1940s and a fifth edition published in 1950. It’s exactly like, but notably predates, Niklas Luhmann’s alphanumeric system which he started in 1952. I’ll write up some of the details shortly with specific references, but thought I’d tease it here a bit first.
While digging about in indexing and filing systems, I ran across this chart created by the Oxford Filing Supply Company for a special Filing Supplies section of the May 1934 issue of Office Appliances magazine (Volume 59, Issue 5). It delineates the broad characteristics of most of the major commercially available filing systems of the era.
Of course, by itself, it may not make much sense, so for those interested in older indexing and filing systems, take a peek at Remington Rand’s textbook Progressive Indexing and Filing (1950) which provides lots of images, examples, and full descriptions by many of the bigger manufacturers.
Perhaps these, which are all fairly similar, may help someone in designing their indexing system for a zettelkasten or commonplace book practices.
The rest of the articles in the magazine also have some fascinating history.
In preparing for some of my end-of-the-year review from my card index, I thought it would be interesting to choose the “Best Note of the Year”. Then it thought it might be worth choosing a “Best Insight”, “Most Surprising Note”, and a “Best Folgezettel” as well.
And if you’re going to give out an award, it should involve a trophy of some sort, right?!? So naturally I went out and picked up a “4 x 6 inch index card” made out of India Black Granite that I plan on engraving with the Note of the Year. At 3/8ths of an inch thick, it is by a large stretch the thickest index card I have in my zettelkasten.
As it may be an interesting end-of-year review practice, I thought I would open up the “competition” to others who’d like to participate. Are there other categories one should enter cards for consideration?
An early 21st century textbook on filing and indexing practices geared toward office workers. First edition, 1932.
The first section is on the rules of alphabetization and indexing to standardize the space of ordering cards for both people’s names and company names.
The second section covers some history on basic filing techniques and then goes into alphabetic, geographic, numeric, and subject indexing methods. The final sections cover the L.B Automatic (Library Bureau), the triple check method, and various other special filing methods as well as maintaining and transferring files for long term storage. Illustrations of these various methods help to visualize how they worked in practice.
This text isn’t as interesting or as comprehensive as the works of J. Kaiser from earlier in the century.

Watching people online chat, ask questions, and generally get excited about their planners for 2026, I thought I would spend a few minutes to set up my Memindex-inspired planner version using 4 x 6″ index cards and tabbed dividers. It’s amazing how useful a $2.50 block of 500 index cards can be for planning out your coming year.
Interestingly, I’ve recently come across versions of this same sort of tickler file recommended in mid-20th century textbooks for filing and indexing in business contexts:
The careful observer will notice that both of the photos in texts by different authors nearly 30 years apart are the same! I would suspect that they’re from a manufacturer’s catalog (Remington Rand) earlier in the century. It’s even more interesting that one can still quickly create such a set up with commercially available analog office supplies now.
Thinking about the current storage capacity of my card index collection, I made a back-of-the-index-card calculation:
172,000 index cards * 150 words / card [average maximum, using front only] * 1,200 bytes / 150 words [rough average with Unicode encoding] * 1 kb / 1024 bytes * 1MB/1024 kb = approximately 200 MB of text storage
I continually think I have written about gutting books in the past, but have only mentioned it and alluded to it. When I bring it up I often get asked about and want to point to my explanation, as there are few resources elsewhere (there is one that surfaced in 2009 from Naomi Standen guiding her students How to gut a book).
For those looking to delve in deeper to gutting books, Mortimer J. Adler and Charles Van Doren go into greater depth in How to Read a Book (Touchstone, 1972, 2011) in which they discuss various levels of reading books with which many students are less familiar. They break reading down into various modes including inspectional reading, analytic reading, and syntopic reading which are the sorts of reading one should be able to accomplish by late high school or certainly by the college level. Unfortunately not too many people are reading this way anymore, if they ever did.
Umberto Eco’s How to Write a Thesis (MIT Press, reprint/translation 2015 [1977]) goes into greater depth on taking one’s guttings and turning them into new material.
For those interested in intellectual history, here’s a chance to join a long standing book club full of inveterate note takers/zettelkasten-ers, educators, and lifelong learners. Those interested in the topic are encouraged to join us.
To join, reach out to Dan Allosso for access to the book club’s shared Obsidian Vault and/or ping me for the Zoom link for the discussions to be held on Saturday mornings at 8:00 – 10:00 AM Pacific over the coming month.
While watching Wedding Crashers (2005, New Line), I noticed that John Beckwith (portrayed by Owen Wilson) and Jeremy Grey (Vince Vaughn) both have multiple card indexes in their offices in the movie.
One can’t help but wondering if their work leverages one of the variety of card index filing systems? Were they commonplacers? Zettelkasten users? Were they maintaining them as basic databases? Monster rolodexes? There are definitely a lot of them around.
It’s obvious that Jeremy actively uses his as in the opening scenes, his card index is on the credenza behind him and later in the movie it has moved.
Vince Vaughn obviously explaining the most important points of knowledge management in the office: a zettelkasten (or card index), bubblegum, and plenty of bourbon.On a side desk in his office Jeremy Gray has a 3×5″ and a 4×6″ card index near all of his most important reference volumes.Along with shelves full of reference books, John Beckwith has a huge collection of card index boxes of various sizes including 3 3×5″ boxes, 3 4×6″ boxes, and even one 5×8″ box.
A Zettelkasten for Wedding Crashers
Of course, the real aficionado of Wedding Crashers will suspect that at least one of Jeremy’s card indexes is full of weddings they’ve crashed, related research, and maybe women he’s encountered. Maybe names and legends of the people they’re pretending to be (“We lost a lot of good men out there.” “Guess who’s a broken man?”) Naturally there would also be a huge section with the numbered rules of wedding crashing as handed down by pioneer Chazz Rheinhold.
IndieWebCamp San Diego 2024 Project Goals
In honor of S. D. Goitein, I have a drawer in my Macey Co. filing cabinet labeled “Genizah” where I put all of my “worn out” notes. They get transferred weekly into the circular file.
Perhaps lamenting too much technology, Dickerson says he’s got two screens on the computer in his office as well as an iPad and a phone. But he’s also got “a notebook [that] does only one thing”. He’s also got an old black lacquer Underwood standard typewriter (No. 4, 5, or 6?) on his office desk. Typewriters only do one thing too.
Wonder if he still uses it?
It seems so on brand for a book about writing using a zettelkasten, that the author would leave a lovely little example of a fleeting note on a slip (1 3/8 x 2 1/2″) inside the front cover of the book!
Dan Allosso’s (Obsidisan) Book Club will be reading Bob Doto‘s book A System for Writing (2024) as their next selection. Discussion meetings are via Zoom for 2 hours on Saturdays starting on 2024-10-19 to 11-02 from 8:00 AM – 10:00 AM Pacific. New comers and veterans are all welcome to attend.
The book is broken up into 3 parts (approximately 50-75 pages each) and we’ll discuss each on succeeding weeks. The group has several inveterate note takers who are well-acquainted with Zettelkasten methods.
If you’d like access to the Obsidian vault, please email danallosso at icloud dot com with your preferred email address to connect to the Dropbox repository.
DM either Dan or myself for the Zoom link for the video meetings.
