Yep, for almost a full year now on 4x6" index cards. (Receipts for the kids: https://boffosocko.com/wp-content/uploads/2023/07/wp-1688411021709-scaled.jpg)

Previously I'd used a Hobonichi Cousin (page per day) journal for this. (Perhaps I should have stayed with the A6 size instead of the larger A5 for consistency?) Decades ago (around 1988ish?) I had started using a 2 page per day DayTimer pocket planners (essentially pre-printed/timed index cards spiral bound into monthly booklets which they actually shipped in index card-like plastic boxes for storage/archival purposes). Technically I've been doing a version of this for a really long time in one form or another.

It generally includes a schedule, to do lists (bullet journal style), and various fleeting notes/journaling similar to the older Memindex format, just done on larger cards for extra space. I generally either fold them in half for pocket storage for the day or carry about in groups for the coming week(s) when I'm away from my desk for extended periods (also with custom blank index card notebooks/pads).

I won't go into the fact that in the 90's I had a 5,000+ person rolodex... or an index card (in the entertainment they called them buck slips) with the phone numbers and names of \~100 people I dealt with regularly when early brick cell phones didn't have great (or any) storage/functionality.

1930s Wilson Memindex Co Index Card Organizer Pre Rolodex Ad Price List Brochure

archived page: https://web.archive.org/web/20230310010450/https://www.ebay.com/itm/165910049390

Includes price lists

List of cards includes: - Dated tab cards for a year from any desired. - Blank tab cards for jottings arranged by subject. - These were sold in 1/2 or 1/3 cut formats - Pocket Alphabets for jottings arranged by letter. - Cash Account Cards [without tabs]. - Extra Record Cards for permanent memoranda. - Monthly Guides for quick reference to future dates. - Blank Guides for filing records by subject.. - Alphabet Guides for filing alphabetically.

Memindex sales brochures recommended the 3 x 5" cards (which had apparently been standardized by 1930 compared to the 5 1/2" width from earlier versions around 1906) because they could be used with other 3 x 5" index card systems.

In the 1930s Wilson Memindex Company sold more of their vest pocket sized 2 1/4 x 4 1/2" systems than 3 x 5" systems.

Some of the difference between the vest sized and regular sized systems choice was based on the size of the particular user's handwriting. It was recommended that those with larger handwriting use the larger cards.

By the 1930's at least the Memindex tag line "An Automatic Memory" was being used, which also gave an indication of the ubiquity of automatization of industrialized life.

The Memindex has proved its success in more than one hundred kinds of business. Highly recommended by men in executive positions, merchants, manufacturers, managers, .... etc.

Notice the gendering of users specifically as men here.

Features: - Sunday cards were sold separately and by my reading were full length tabs rather than 1/6 tabs like the other six days of the week - Lids were custom fit to the bases and needed to be ordered together - The Memindex Jr. held 400 cards versus the larger 9 inch standard trays which had space for 800 cards and block (presumably a block to hold them up or at an angle when partially empty).

The Memindex Jr., according to a price sheet in the 1930s, was used "extensively as an advertising gift".

The Memindex system had cards available in bundles of 100 that were labeled with the heading "Things to Keep in Sight".

Arthur introduces the topic of Robert Pirsig and slips into the GTD conversation on 2004-05-19.

Was this a precursor link to the Pile of Index Cards in 2006?

Note that there doesn't seem to be any discussion of any of the methods with respect to direct knowledge management until the very end in which arthur returns almost four months later to describe a 4 x 6" card index with various topics he's using for filing away his knowledge on cards. He's essentially recreated the index card based commonplace book suggested by Robert Pirsig in Lila.

PVA Glue used in bookbinding, but isn't inexpensive.

• Tacky glue - okay
• rubber cement - not great
• elmer's glue - not great, tears esp. for 2 layers
• Mod podge - pulls nicely and strong
• mod podge hard shell - cracks, not great
• PVA Glue - the best of the group

Recommendations in order: PVA, Tacky Glue, Mod Podge (regular)

Brush on top edge and do two coats. Don't get it down between sheets.

Dwyer, Edward J. “File Card Efficiency.” Journal of Reading 26, no. 2 (1982): 171–171.

Ease of use in writing and grading with short assignments by using 4 x 6" index cards in classrooms.

This sounds like some of the articles from 1912 and 1917 about efficiency of card indexes for teaching.

I'm reminded of some programmed learning texts that were card-based (or really strip-based since they were published in book form) in the 1960s and 1970s. Thse books had small strips with lessons or questions on the front with the answers on the reverse. One would read in strips through the book from front to back and then start the book all over again on page one on the second row of strips and so on.

While it may be slightly more difficult to find larger metal/wood cases for the 4x6 or 5x8 cards, it's a minor nuisance and anyone who wants them will eventually find the right thing for them. Beyond this, choose the card size that feels right to you.

If you don't have an idea of what you need or like, try things out for 10-20 cards and see how it works for you, your handwriting size, and general needs. People have been using 3x5, 4x6, and even larger for hundreds of years without complaining about any major issues. If Carl Linnaeus managed to be okay with 3x5, which he hand cut by the way, I suspect you'll manage too.

Of course I won't mention to the Americans the cleverness of the A6, A5, A4 paper standards which allows you to fold the larger sizes in half to get the exact next smaller size down. Then you might get the benefit of the smaller size as well as the larger which could be folded into your collection of smaller cards, you just have to watch out for accidentally wrapping ("taco-ing") a smaller card inside of a larger one and losing it. I suppose you could hand cut your own 5" x 6" larger cards to do this if you found that you occasionally needed them.

For the pocketbook conscious, 3x5 does have the benefit of lower cost as well as many more options and flexibility than larger sizes.

At least commercial card sizes are now largely standardized, so you don't have deal with changing sizes the way Roland Barthes did over his lifetime.

My personal experience and a long history of so many manuals on the topic saying "cards of the same size" indicates that you assuredly won't have fun mixing different sized slips together. I personally use 3x5" cards in a waste book sense, but my main/permanent collection is in 4x6" format. Sometimes I think I should have done 3 x 5, but it's more like jealousy than regret, particularly when it comes to the potential of a restored fine furniture card catalog. But then again...
