As We May Think Alive
The Atlantic essay that imagined the Memex — associative trails through stored knowledge. Engelbart and Nelson read it as a blueprint; hypertext was the result.
Bush was director of the wartime OSRD when he wrote this Atlantic Monthly essay. His hypothetical 'memex' was a desk containing a scholar's entire library on microfilm, where documents could be linked into 'trails of association' and the trails themselves stored, shared, and extended — a machine for augmenting memory, not calculating.
The machine was never built; the idea was everything. Douglas Engelbart cited it directly, Ted Nelson coined 'hypertext' pursuing it, and Tim Berners-Lee worked in its lineage. The essay's real prediction was that the bottleneck of knowledge work would be retrieval and association, not storage.
