  1. 1. The Memex The Personal MemoryExtender That Never Was David Lavenda – May 2011
  2. 2. Vannevar Bush (1890-1974)
  3. 3. The BackdropWWII – Partially, A Scientist’s War
  4. 4. “As We May Think”  July 1945  Seminal article in the history of computing  Introduces the memex
  5. 5. Information Overload“There is a growing mountain of research.But there is increased evidence that we arebeing bogged down today as specializationextends. The investigator is staggered bythe findings and conclusions of thousandsof other workers— conclusions which hecannot find time to grasp, much less toremember, as they appear...” (1945)“The difficulty seems to be…thatpublication has been extended far beyondour present ability to make real use of therecord.” (1945)“We are being buried in our own product.Tons of printed material are dumped outevery week. Many [ideas] become lost;many others are repeated over and over.”(1967)
  6. 6. The Memex“Consider a future device for individualuse, which is a sort of mechanized privatefile and library…A memex is a device in which an individualstores all his books, records, andcommunications, and which is mechanizedso that it may be consulted with exceedingspeed and flexibility. It is an enlargedintimate supplement to his memory.” Source: As We May Think, Vannevar Bush, 1945
  7. 7. How Much Information?“…if the user inserted 5000 pages of material a day itwould take him hundreds of years to fill therepository, so that he can be profligate and entermaterial freely” Source: Vannevar Bush, “As We May Think”, 1945
  8. 8. The Memex – Dissected Touch sensitive screens for displaying information and adding annotationsScanner and touch sensitive screen Current „trail number‟ display Stylus „keypad‟ for enteringNavigation switch trail codes Memory storage microfilm, magnetic tape
  9. 9. What Happened to the Memex? Bush „upgrades‟ the memex in 1959 and 1967  Magnetic tape replaces microfilm  Proposed that crystals will replace magnetic tape  Still analog Was never built
  10. 10. Analyzing The Memex Why wasn‟t it ever built? What was its impact on future developments? Why is it important?
  11. 11. Why Wasn’t The Memex Ever Built? According to Bush:  It would have been „enormously expensive‟ to build  It was an idea before its time  Creating associations between was not well understood  Public didn‟t understand the value of the project Others:  Device was too ambiguous; no good definition  No practical way to create associations  Associations aren‟t the best way to link information  Technologies were not ripe for use; e.g. info retrieval Sources: Bush, V., Memex Revisited, 1959, and Memex II, 1967.
