Shohei Ohtani, a designated hitter and pitcher for the Los Angeles Dodgers, is one of the biggest superstars in baseball right now. If you’re Jose Siri on the Los Angeles Angels, you know that to get Ohtani out, you’re going to need some serious notes on an index card to score the out. The problem is, what do you do when the hit happens on the first pitch, and you’re not quite ready?
My screen captures from the Angels at Dodgers’ baseball game at UNIQLO Field in Los Angeles on Sunday, June 7, 2026 at the bottom of the first inning. Pitcher Jose Soriano faces batter Shohei Ohtani who, on the first pitch, flies out (F8) to Jose Siri in center field. Siri has all the data and skill he needs.
Only in LA?!?
That looks like a 4×6 inch index card right?

Solid one-handed catch because he’s got his scouting data on a card in his other hand.How do you throw the baseball back when your right hand is occupied?
I’ve got the card out, I may as well study for the next batter.Siri back in ready position. He won’t be “caught out” for the next batter.
I’m really hoping this book Index to Murder is a gift of thoughtfulness and not some perverse, veiled threat.
This nearly indestructible black and gray powder-coated 20 gauge steel constructed 8 drawer cabinet with art deco flourishes has 36 linear feet of storage space for over 2,000 Field Notes notebooks.
This is enough space for over 83 years’ worth of subscription to the quarterly notebooks. Literally enough space for a lifetime of notes.
Staple Day, eat your heart out! We’re stalking down the elusive 4 Drawer Day!
I’ve just noticed that Zotero update 7.0.31 added specific fields for Original Place, Original Publisher, and Original Date for books. Even better, the books for which I had defined an “Original-date” in the Extra section automatically sucked in that data and updated my database! Good work development team!
Someone recently mentioned to me that the small, portable 1,000 index card capacity cardboard box with lid that they use as a zettelkasten felt more like it was for deep storage rather than daily use. Perhaps it’s a result of the fact that this is how most people have been using these cheaper cardboard boxes for the last 30+ years? They said they’d prefer to have a drawer or a box with an attached lid.
It dawns on me that I’ve never mentioned one of the great affordances of many of the older card index cabinets is that they’re designed to be able to completely remove one or more drawers at a time and use at your desk. On an almost daily basis, I pull out at least one drawer from my cabinet and place it on my desk and it allows me to actively work with collections of over 7,000 cards at a time. This means that while the cabinet itself may seem like deep or “cold” storage, it’s really ongoing active storage that I can quickly and easily interact with depending on the range of projects I may be dealing with on a given day. Working on a different project for a bit? Put one drawer away and pull another…
Several of my cabinets have not only pull handles on the front of the drawers, but also have cut-out handles in the rear to be able to easily pull them out and move them around. This feature was also the reason many cabinets also had card rods. The cards could be physically held into the drawers to prevent the user from accidentally tipping the drawer and loosing all the cards into a random pile on the floor. Robert Pirsig describes a sad affair similar to this in his book Lila: An Inquiry into Morals (Bantam Books, 1991).
Of course at the end of the day I can quickly slot the drawer right back into the cabinet for that clean desk look. And because today is the one year anniversary of the Eaton Fire, I’ll mention that it’s also pretty easy to pull a few of your favorite drawers out of the filing cabinet for fleeing your home office, evacuating your town, and being able to work for four months remotely. (Just remember to seat belt those drawers into the back seat if you don’t have card rods!)
The internet is now rife with what I call “zettelkasten method one pagers” that describe what many people rightly (or very often wrongly) think that Niklas Luhmann’s zettelkasten method entails.
While doing some research about Luhmann’s numbering system’s antecedents, I recently came across a “one pager” (typescript) written by Luhmann himself in the form of some lecture notes from 1968 that folks may appreciate.
Seemingly everyone with a blog that ran across the idea of Zettelkasten in the last decade or so wrote up their own description of what it is. If you know of other blog posts about zettelkasten, let me know for my collection.
Of special note to those who are still under the misapprehension that Luhmann “invented the zettelkasten”, in the closing section of his 1968 notes he writes “In conclusion: from personal experience, others work differently” by which one understands that he’s aware of others who use similar systems and admits that they’re all idiosyncratic to their individual users. I would suspect that he gave this lecture while at Sozialforschungsstelle an der Universität Münster (Social Research Centre of the University of Münster) to students about how to arrange and do their own sociology research work.
Wishing all my friends and fellow note takers a happy holidays!
Stocking stuffers anyone? Santa brought 6,000 index cards down the proverbial chimney today. Should have enough now to index all the books in the house?
Keep your A6 notebooks, pens, and essentials organized on the go with the Field Folio A6. Durable, vegan waxed canvas, slim design, and flexible pockets—perfect for travel, journaling, or everyday carry.
I recently asked the kind folks at Lochby “if the Folio A6 will comfortably fit 25-50 standard 4 x 6″ index cards which are slightly larger than an A6 notebook? If not, is it something you might consider for some of us ‘Hipster PDA’ tribe members in the future?”
Erring on the side of caution their customer service replied, “Unfortunately, since the Field Folio A6 zips up, there’s no way to fit this many index cards in it without the potential for damaging them when zipping it up. But I’ll take note of your suggestion and pass it on to our product development team so we can consider it as well as gauge interest.”
Because I often use A6 sized notebooks, I couldn’t resist adding to my Lochby collection, so I went ahead and ordered it anyway.
It arrived in the post yesterday. Today I’m happy to report that it actually will accommodate 4 x 6″ index cards reasonably well. I can comfortably fit about 30 cards into the right side pocket and still have room to tuck a Hobonichi A6 notebook into the folio and still zip it shut handily.
Because I usually have a few pre-glued decks of index card “notebooks” sitting around, I tried one of these and can happily report that the back cover/board fits into the right pocket easily (just as you’d tuck the back cover of a notebook into it) and works well with the Lochby A6 folio! (The center elastic bands are slightly smaller and fairly tight, and could work with these glued decks too, but will tend to cut the glue at the ends, so one should take care here or carefully only glue the center 5 inches of the deck for this use case.) I suspect that if one had a plastic wallet-photo type holder, it might work well in this, particularly if you’re carrying around some of your daily use cards in addition to blank cards for future use.
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.
