Duly Noted: Extend Your Mind through Connected Notes is a 2024 book by information architect Jorge Arango on building a personal note system whose value lies in the links between notes rather than in the notes themselves.
Arango's argument is that a note collection becomes useful at the point where notes reference one another, because connection is what lets an idea resurface in a context you could not have anticipated when you wrote it. The book works through capture, structuring, linking, and revisiting, and treats the whole practice as ongoing tending rather than as filing. It carries a foreword by Howard Rheingold and was published by Two Waves Books.
The book sits in the lineage running from 📝Niklas Luhmann's 📝Zettelkasten through contemporary 📝Personal Knowledge Management frameworks such as 📝Building a Second Brain (BASB). Arango arrives at the subject from information architecture rather than from productivity, and the emphasis shifts accordingly: less on capture workflows and processing rituals, more on how structure, naming, and linking determine whether a note can be found again at all.
📝Harry Max recommended this to me — Jorge is his co-host on his podcast, and Harry thought we had very similar ways of thinking about connected context.
