Beat Signer - Department of Computer Science - bsigner@vub.ac.be 6 February 9, 2021 "As We May Think" (1945) When data of any sort are placed in storage, they are filed alphabetically or numerically, and information is found (when it is) by tracing it down from subclass to subclass. It can be in only one place, unless duplicates are used; one has to have rules as to which path will locate it, and the rules are cumbers- ome. Having found one item, moreover, one has to emerge from the system and re-enter on a new path. The human mind does not work that way. It operates by association. ... Vannevar Bush

Beat Signer - Department of Computer Science - bsigner@vub.ac.be 7 February 9, 2021 "As We May Think" (1945) … ... It affords an immediate step, however, to associative indexing, the basic idea of which is a provision whereby any item may be caused at will to select immediately and automatically another. This is the essential feature of the memex. The process of tying two items together is the important thing. ... Vannevar Bush, As We May Think, Atlanic Monthly, July 1945 Vannevar Bush

Beat Signer - Department of Computer Science - bsigner@vub.ac.be 8 February 9, 2021 "As We May Think" (1945) … ▪ Bush's article 'As We May Think' (1945) is often seen as the "origin" of hypertext ▪ Article introduces the Memex ▪ memory extender ▪ store and access information ▪ follow cross-references in the form of associative trails between pieces of information (microfilms) ▪ prototypical hypertext machine ▪ trail blazers are those who find delight in the task of establishing useful trails Memex

Beat Signer - Department of Computer Science - bsigner@vub.ac.be 13 February 9, 2021 Digital Documents as a Paper Simulator? Most people don't understand the logic of the concept: "What You See Is What You Get" is based on printing the document out ("get" means "get WHEN YOU PRINT IT OUT"). And that means a metaphysical shift: a document can only consist of what can be printed! This re-froze the computer document into a closed rectangular object which cannot be penetrated by outside markings (curtailing what you could do with paper). No marginal notes, no sticky notes, no crossouts, no insertions, no overlays, no highlighting - PAPER UNDER GLASS.
