Archive.org is an incredible website where you can get some rare audio, video and text stuff free to download.

Here are some good stuff I found about Douglas :

- Interview. Shockwave Radio Theater November 9, 1993 with guest Douglas Adams

- A TV documentary from 1988 about computer games. Douglas Adams is interviewed about Bureaucracy

Archive.net also features "wayback machine" which allows you to browse through 85 billion web pages archived from 1996 to a few months ago. Very handy if you want to find some internet websites which are not online anymore like MJ Simpson's Planet Magrathea,
