Mundaneum

The Mundaneum was an institution which aimed to gather together all the world's knowledge and classify it according to a system known as the Universal Decimal Classification. It was developed at the turn of the 20th century by Belgian lawyers Paul Otlet and Henri La Fontaine. The Mundaneum has been identified as a milestone in the history of data collection and management, and, albeit more tenuously, as a precursor to the Internet.

In the 21st century, the Mundaneum is a non-profit organisation based in Mons, Belgium, that runs an exhibition space, website, and archive, which celebrate the legacy of the original Mundaneum.
