2016 marks the 20th anniversary of the Knowledge Base of Futures Studies (KBFS). It first appeared as a special issue of Futures in March 1993. Besides the editorial it contained 7 original papers, 10 ‘divergent perspectives’ (from as many different countries) and no fewer than 5 bibliographies. The first book edition was a three-volume set presented in a sturdy slipcase. The first volume covered Foundations, the second Organisations, Practices and Products and the third Directions and Outlooks. It was officially launched at a World Future Society Conference (WFS) in Washington DC during July 1996. Hughes de Jouvenel, Wendell Bell and Hazel Henderson assisted with the launch. Two further hard copy editions followed. Then in 1999 and 2000 my son Rohan and I converted the original files into html documents and assembled the first CD-ROM. It was followed in 2005 by an expanded 5 volume professional edition that was subsequently adopted for university courses around the world. A succinct account of how and why the KBFS was developed, along with some of the feedback it received, can be found on the FI site here. Also see here under Futures Archive.
