Vannevar Bush's Memex

Every now and then, I like to revisit Vannevar Bush’s classic article from the July 1945 edition of the Atlantic Monthly called As We May Think in which he describes a theoretical machine called the memex.

A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory.

It consists of a desk, and while it can presumably be operated from a distance, it is primarily the piece of furniture at which he works. On the top are slanting translucent screens, on which material can be projected for convenient reading. There is a keyboard, and sets of buttons and levers. Otherwise it looks like an ordinary desk.

1945! Apart from its analogue rather than digital nature, it’s a remarkably prescient vision. In particular, there’s the idea of “associative trails”:

Wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified. The lawyer has at his touch the associated opinions and decisions of his whole experience, and of the experience of friends and authorities.


And now I’m using the World Wide Web, a hypermedia system that takes in the whole planet, to create an associative trail. In this post, I’m linking (without asking anyone for permission) to six different sources, and in doing so, I’m creating a unique associative trail. And because this post has a URL (that won’t change), you are free to take it and make it part of your own associative trail on your digital memex.
