The Mundaneum was an institution created in 01910 by Belgian lawyers Paul Otlet and Henri La Fontaine. It aimed to gather together all the world’s knowledge and classify it according to a system they developed called the Universal Decimal Classification. Otlet regarded the project as the centerpiece of a new ‘world city’—a centrepiece which eventually became an archive with more than 12 million index cards and documents. Some consider it a forerunner of the Internet (or, perhaps more appropriately, of systematic knowledge projects such as Wikipedia) and Otlet himself had dreams that one day, somehow, all the information he collected could be accessed by people from the comfort of their own homes.
