Memex

The memex (memory extender) was a desk-sized machine Bush described in 'As We May Think'—a device in which an individual stores books, records, and communications, mechanized for consultation with exceeding speed and flexibility. Users would view documents on translucent screens, create links between related items, and build trails through the knowledge base that others could follow. The memex's innovation was not storage capacity but navigational flexibility: it would support the associative, non-linear way the human mind actually works rather than forcing alphabetical or hierarchical organization. Bush imagined professional researchers—scientists, physicians, lawyers—using the memex to manage the growing mountain of specialized knowledge. The device was never built; analog technology was overtaken by digital computing. But the conceptual framework survived and shaped the development of hypertext systems, personal databases, and the architectural principles of the World Wide Web.
