a second use of "mental card catalogue", though somehow he doesn't seem to realize the inherent value for building knowledge... ?

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".

Interesting that the use of the portmanteau memindex (as memory + index) for a card index being used to supplement one's memory. It can't go unnoticed that the Wilson Memindex Co. was manufacturing and selling these as early as 1906, several decades before Vannevar Bush's use of the word Memex which seems derivative and removes more of the traces of index from the root.

Note the use of card sizes 2 3/4 x 4 1/2" and 3 x 5 1/2" for this system.

A partial answer to note taking why.

use of "mental card catalogue" as memory

"Nullum numen abest si sit prudentia, is unquestionably true, with regard to every thing except poetry; and I am very sure that any man of common understanding may, by proper culture, care, attention, and labour, make himself whatever he pleases, except a good poet." Chesterfield, Letter lxxxi.

Take notes for your most imperfect, forgetful future self. You're assuredly not only not going to remember either the thing you are taking notes for in the first place, but you're highly unlikely to remember why you thought it was interesting or intriguing or that clever thing you initially thought of at the same time.

Capture all of this quickly in the moment, particularly the interesting links to other things in your repository of notes. These ideas will be incredibly difficult, if not impossible, for one to remember.

I would suggest that this is wholly wrong as both of the memories described are honed for specific situations and not broadly applicable.

Even those with good natural memories as well as those with significant mnemonic practices can benefit from a structured note taking practice.

Earl Pomeroy suggests that Paxson's note taking method freed his mind to better reflect and appraise his work. This allows a greater efficiency of work, particularly when it comes to easier search and recall as well as the overall process which becomes easier through practice.

Again he uses the idea of a "file" which I read and understand as similar to the concepts of zettelkasten or commonplace book. Unlike others writing about these concepts though, he seems to be taking a more holistic and integrative (life) approach to having and maintaining such system.

Perhaps a more extreme statement of this might be written as "zettelkasten is life" or the even more extreme "life is zettelkasten"?

Is his grounding in sociology responsible for framing it as a "social organization" of one's memory?

It's not explicit, but this statement could be used as underpinning or informing the idea of using a card index as autobiography.

How does this compare to other examples of this as a function?

Beatrice Webb sees the primary uses of notes as a memory device and a discovery device.

A card index can be a massive boon to a writer as a well-indexed one, in particular, will save massive amounts of time which might otherwise be spent searching for quotes or ideas that they know they know, but can't easily recreate.
