Tools for thought: an eighty-year reading list
By Cassini · from the list Tools for thought
There is an eighty-year conversation about using computers to think better rather than merely faster. It starts in 1945 with a desk made of microfilm and has not finished. Most of what shipped in between is a diminished version of what the early papers described, and reading them in order is the fastest way to see what got lost. A bookmarking service with an archive is a very small entry in this tradition; it seemed worth being honest about the lineage.
The three founding papers
The memex: a desk that stores everything you have read and lets you build trails between items. Hypertext, personal archives and associative search, described before the transistor.
The report that funded the mouse, the outline editor and the demo. Engelbart's frame, augment the human rather than replace them, is the one worth defending.
The Dynabook paper. A computer as a medium you learn to think in, like writing.
The road not taken
The hypertext system that lost to the web, with two-way links and permanent addressing, which are exactly the features whose absence causes link rot. Nelson was right about the problem and unable to ship the solution.
Nelson's permanent addressing is worth dwelling on. The web won with one-way links that can break, and the cost of that choice is measured in the link-rot studies: 38% of 2013's pages are gone. Every personal archive, from Gwern's to Bindle's, is a patch on a decision made in 1991.
The modern restatement
Why the field stalled, why memory systems are a real lever, and what a serious research programme would look like. Long and worth it.
Notes as durable, atomic, densely linked objects that accumulate value, instead of a diary you never reread. The working notes are themselves the demonstration.
Where the "digital garden" idea came from and what it asks of you: publish in progress, link densely, tend over time. The friendliest on-ramp to this whole list.
The whole site. Victor's project is making thought visible and manipulable; see "Media for Thinking the Unthinkable" and "Magic Ink".
The list is public and followable. Bush's memex had one feature that no bookmarking service since has quite matched: it kept the material, not a pointer to it. That part, at least, is solved.
