Class 2, Does Memory Matter? Why Are Universities Studying Slavery and Their Pasts? by David Blight for [[YaleCourses]]

Theatres of Memory (1994) sounds like it's taking lots of examples from a zettelkasten and tying them together.

It's also interesting to note that he published several books posthumously. Was this accomplished in part due to his zettelkasten notes the way others like Ludwig Wittgenstein?

1:09 He puts the question forward: "why is the material on zettelkasten so divergent?" Well, it has been, historically speaking. There is no one way to keep a zettelkasten. What the person is pointing at, I think, is why are practices so divergent from Niklas Luhmann?

A fascinating combination of office furniture types in 1906!

The Adjustable Table Company of Grand Rapids, Michigan manufactured a combination table for both telephones and index cards. It was designed as an accessory to be stood next to one's desk to accommodate a telephone at the beginning of the telephone era and also served as storage for one's card index.

Given the broad business-based use of the card index at the time and the newness of the telephone, this piece of furniture likely was not designed as an early proto-rolodex, though it certainly could have been (and very well may have likely been) used as such in practice.

I totally want one of these as a side table for my couch/reading chair for both storing index cards and as a temporary writing surface while reading!

This could also be an early precursor to Twitter!

Folks have certainly mentioned other incarnations: - annotations in books (person to self), - postcards (person to person), - the telegraph (person to person and possibly to others by personal communication or newspaper distribution)

but this is the first version of short note user interface for both creation, storage, and distribution by means of electrical transmission (via telephone) with a bigger network (still person to person, but with potential for easy/cheap distribution to more than a single person)

Interesting to see the first post on zettelkasten.de in 2013 has a photo of hawkexpress' Pile of Index Cards (PoIC) in it.

This obviously means that Christian Tietze had at least a passing familiarity with that system, though it differed structurally from Luhmann's version of zettelkasten.

Historically the vast majority of zettelkasten didn't have the sort of structure and design of Luhmann's, though with indexing they certainly create a network of notes and excerpts. These examples are just subsets or excerpts of someone's reading of these books and surely anyone else reading any book is going to have a unique set of notes on them. These sets were specifically honed and curated for a particular purpose.

The interesting pattern here is that someone is selling a subset of their work/notes as a set of cards rather than as a book. Doing this allows different sorts of reading and uses than a "traditional" book would.

I'm curious what other sort of experimental things people might come up with? The "novel" Cain's Jawbone, for example, could be considered a "Zettelkasten mystery" or "Zettelkasten puzzle". There's also the subset of cards from Roland Barthes' fichier boîte (French for zettelkasten), which was published posthumously as Mourning Diary.

In order to become a free-standing tool, the card index needed to have self-referential closure.

This may have been one of the necessary steps for the early ideas behind computers. In addition to the idea of a clockwork universe, the index card may have been a step towards early efforts at creating the modern computer.

1. Placcius 1689, p. 72.

Vincentius Placcius in De Arte Excerpendi: Of Scholarly Book Organization (1689) offers a contemporary set of instructions on excerpting knowledge as well as a history of the subject.

In the book, he warns specifically against the loose form of indexing exhibited by Joachim Jungius. (p72)
