The Memex is a theoretical personal device designed to extend human memory by storing vast amounts of information and allowing users to access it quickly and efficiently. In terms of structure, it’s essentially a mechanized desk internally containing a large library of microfilmed books, records, and communications, all accessible through screens, which are controlled by levers and buttons. The core functionality that became the inspiration for hypertext is its ability to create associative “trails” between pieces of information, mimicking the way the human mind forms connections rather than organizing knowledge strictly by alphabetical or numerical order. A user could link related documents together, build personalized paths through the material, and store these trails for later retrieval or sharing, effectively creating a dynamic, interconnected system of knowledge that anticipates modern hypertext and digital information networks.
