Chris, I read it some 40 years ago when as a school boy I began with my Zettelkasten journey. It is about the technique as well as the intellectuell framework behind it and was surely pointed to business aspects as well as running the civil service but also outspoken to the worker of the mind, the scientist and philosopher. Filing and indexing is crucial to all of these varied aspects of cultural life. But don't expect hitherto unknown magical practices to be revealed. It was commune practice then and you could find handbooks on indexing and filing in organisations also in America and England at that time. The new found way of personal knowlegde management just doesn't know about its predecessors with pen, ink, typewriter and other unbeliefable tricks.

I've come across Porstmann a few times as the "intellectual father of the A-Series", the "creator of the DIN formats", and the creator of A4 in various contexts. I saw that he wrote an interesting looking handbook in the mid-1920s and was curious if anyone has come across or even read it? It looks like it went into three editions up to the 1950s. I'm not seeing any English translations at present. I suspect it has material on using card indexes as databases and may be focused on business use, but may also have some connections to note taking practices of the time. I've also found several references to Porstmann's work and that of George Christoph Lichtenberg which makes me even more curious about the potential note taking connections.

Über die Karteikartentechnik wurde sogar ein wunderbares Buch geschrieben: Karteikunde, Das Handbuch der Karteikartentechnik von Dr. Walter Porstmann.
A wonderful book has even been written about the index card technique: Index Cardology, The Handbook of Index Card Technique by Dr. Walter Porstmann.

The first time the ratio of length to width was written in a letter dated 25 October 1786. This letter was from the German Georg Christoph Lichtenberg to Johann Beckmann. He wrote here about the advantages of basing paper on a √2 ratio. Lichtenberg is known for the ratio between length and width of a surface which remains the same after the narrated halving of the surface. The result is 1:√2.
