The idea of the internet was born in Belgium. Idea No.1: The Mundaneum 
The unsung heroes of the Internet 
Our view is that the creative ways in which he [Paul Otlet] faces tensions of scalability, representation, and perception of relationships between knowledge objects might be of interest today.
He also wrote extensively about the need for a universal network for the communication of knowledge. His theoretical approach to the organi-zation and dissemination of information was far ahead of its time, notably in foreshadowing the Internet, Hypertext, and the World Wide Web.
Building Society, Constructing Knowledge, Weaving the Web: Otlet’s Visualizations of a Global Information Society and His Concept of a Universal Civilization
Paul Otlet's visionary Mundaneum was a proto-internet made of 3-by-5-inch index cards 
Otlet imagined a day when users would access the database from great distances by means of an “electric telescope” connected through a telephone line, retrieving a facsimile image to be projected remotely on a flat screen. In Otlet’s time, this notion of networked documents was still so novel that no one had a word to describe these relationships, until he invented one: “links.” Otlet envisioned the whole endeavor as a great “réseau”—web—of human knowledge.
