The Mundaneum Was a Paper Internet

In 1895, Paul Otlet and Henri La Fontaine built a paper internet with 18MM index cards affectionately referred to as the Mundaneum. They sought to catalog the world’s information (much like Google) but quickly ran into the physical limitations of such a thing. As more information was added, they realized the 15,000 drawers needed to hold all those index cards was never going to be enough.
