CREATING VALUE WITH WEBSITES.
INTRODUCTION  HISTORY

September 10, 1945

VANNEVAR BUSH  He created ‘the memex’

De Memex is een door de Amerikaanse
wetenschapper Vannevar Bush in de jaren 30 van de
twintigste eeuw voorgesteld concept voor "een
op microfilm gebaseerd apparaat waarin iemand al zijn
belangrijke gegevens, boeken en communicatie met
derden zou kunnen opslaan en dat zodanig
georganiseerd zou zijn, dat de erin
ondergebrachte informatie pijlsnel en uiterst flexibel
zou kunnen worden opgeroepen en geraadpleegd." Met andere woorden: de Memex (een
afkorting voor Memory Extender) zou zich moeten gedragen als een ideaal verlengstuk van het
individuele, menselijke geheugen: snel, alomvattend en intuïtief.
