At this year's Wikimania conference I was talking to Cormac about my dissertation and how at the beginning of the 20th century some like Wells and Otlet were inspired about the potentials of technology (i.e., microfilm and index cards) and their possible contributions towards a universal encyclopedia. Cormac noted that Cunningham had actually mentioned index cards in his Wikimania 2005 presentation, which I was not able to attend. Fortunately, I was able to find a copy of the video and my rough notes on it are available (Cunningham 2005).
