"The amount of audio-visual material that Duncan [Makenzie] had stored under MISC was remarkable, even for an inquisitive ten-year old. It was not that he lacked organizing ability - that was the most celebrated of all the Makenzie talents - but he was interested in more things than he knew how to index. He had now begun to discover, the hard way, that information not properly classified can be irretrievably lost."
Arthur C. Clarke, Imperial Earth (1975/1982), Aylesbury: Pan Books, p. 16
