“The Indexers pose with the file of Great Ideas. At sides stand editors [Mortimer] Adler (left) and [William] Gorman (right). Each file drawer contains index references to a Great Idea. In center are the works of the 71 authors which constitute the Great Books.” From “The 102 Great Ideas: Scholars Complete a Monumental Catalog,” Life 24, no. 4 (26 January 1948).

This sounds similar to the variety of calls to do collaborative card indexes for scientific efforts, particularly those found in the fall of 1899 in the journal Science.

This is also very similar to Mortimer J. Adler et al's group collaboration to produce The Syntopicon as well as his work on Propædia and Encyclopædia Britannica.

Someone's creating a new digitally linked version of the Syntopicon as text files for Obsidian (and potentially other platforms). Looks like it's partial at best and will need a lot of editing work to become whole.

Has anyone made a hypermedia rendition of the Syntopicon, i.e. with transcluded windows or "parallel pages" into the indexed texts?<br><br>Many of Adler's Great Books are public domain, so it wouldn't require *so* titanic a copyright issue… pic.twitter.com/UmWiyn5aBC

None appear to have details about the card collection used for compiling the encyclopedia or Syntopicon.

Though if we roughly estimate this collection at 1000 cards per box with roughly 76 boxes potentially present, the 76,000 cards are still shy of Luhmann's collection. It'll take some hunting thigs down, but as Adler suggests that people write their notes in their books, which he would have likely done, then this collection isn't necessarily his own. I suspect, but don't yet have definitive proof, that it was created as a group effort for the 54-volume Great Books of the Western World and its two-volume index of great ideas, the Syntopicon.

Reminded by Connor of Mortimer Adler's Syntopicon. I'm pretty sure I've got it in my list of encyclopedias growing out of the commonplace book tradition, but... just in case.

If I recall it was compiled using index cards, thus also placing it in the zettelkasten tradition.

If you’re generalizing Zettelkasten to “All Non-Linear Knowledge Management Strategies” You should include Mortimer Adler and the Syntopicon, and John Locke’s guide to how to set up a commonplace book<br><br>This isn’t a game of calling “dibs”<br><br>it’s about 🧠👶shttps://t.co/sH3JO6d9Jq
