Google: the Citation Index
I just finished reading Kevin Kelly's "Out of Control", and throughout I was amazed that it felt progressive and bold today, 14 years after it was first published. A passage near the end includes a little bit of a non-sequitur that discusses the then new concept of electronic, hyperlinked citation indexing, and in his description, Kelly basically describes the fundamental insight that makes Google work, four years before the twins launched their search engine. This guy was on top of things in '94.
