PAUL OTLET an analog version of Google. The Man Who Wanted to Classify the World
Networked Knowledge, Decades Before Google
By Meike Laaff
He dreamed of a "mechanical, collective brain" and his complex system for indexing information could be considered an analog version of Google. Belgian lawyer and librarian Paul Otlet died in 1944, poor and disillusioned. But his work is now being looked at in a whole new light.
Info The world's first search engine is made of wood and paper. Specifically, it consists of rows of dark brown cabinets about as tall as a person, filled with boxes of index cards. "Sixteen million index cards," notes Jacques Gillen, laying one hand on a cabinet handle. Gillen is an archivist at the Mundaneum, the institution that operated this gigantic catalogue in the 1920s. Inquiries came into Brussels by letter or telegram, as many as 1,500 of them a year, and the answers were then found by hand, a process that sometimes took weeks. The project was something like a paper Google, but developed decades before the Internet and without the benefit of computers.
Belgian librarian Paul Otlet created the Mundaneum. A trained lawyer from a wealthy family, Otlet wanted to map out the world's knowledge and preserve it in his wooden cabinets. He envisioned collecting all of the books ever published and interlinking them using an archival system he developed himself.
Gillen, the archivist, fishes an index card out of a box. From the jumble of numbers written on the card, he can decipher dozens of pieces of information about the book to which the card refers. Many modern researchers agree that with this archival system, developed around the turn of the last century, Otlet essentially invented hypertext, the network of links that help us navigate around the Internet today. "You could call Otlet one of the original minds behind the Internet," Gillen says, placing the card back in its box.
A Global Knowledge 'Network'Otlet first developed the idea of a global knowledge "network" in 1934. At a time when radio and television were still in their infancy, he tried to develop multimedia concepts to improve opportunities for cooperation among researchers. Otlet wrestled with the question of how to make knowledge accessible across great distances. He used a combination of index cards, telephones and other equipment to approximate what is possible today with any computer.
Similarly, without the aid of electronic data processing, Otlet developed ideas whose application we know today under names such as Web 2.0 and Wikipedia. Yet Otlet's name and his work are largely forgotten. Americans Vannevar Bush, Ted Nelson and Douglas Engelbart are considered the minds behind hypertext and the Internet, while the remains of the Mundaneum collection spent decades rotting in dilapidated attics.
The Mundaneum began in the early 20th century as a dazzling success story. Otlet and his colleague Henri La Fontaine, who later won a Nobel Peace Prize, had been working on the project since 1895. The Mundaneum, which opened its doors in 1920 in a grand building in the heart of Brussels, was a mixture of public museum and meeting place for scholars, with an enormous catalogue of information, as well as an archive.
The archive contained not only books, but also countless newspapers, posters and more than 200,000 postcards, as well as samples of everything from airplanes to telephones. There was so much material that it soon threatened to overwhelm the project. But Otlet and his colleagues were on a mission, convinced that the global dispersal of knowledge could promote peace. To these ends, they worked in close collaboration with other research institutions abroad. A Paperless Way of Spreading Information
Alongside his passion for collecting, Otlet worked on new ideas for the paperless dissemination of knowledge. He saw books as nothing more than "containers for ideas," ones which could be replaced by more practical media, for example graphics and diagrams, of which he himself produced countless examples. These saved space because they could be recorded on microfilm, and had the added benefit of being internationally comprehensible. Otlet also hoped to use audio and film to make it possible to transport information faster, further and more easily.
Otlet collected all of these ideas in his 400-page book "Trait de documentation." He laid out the concept of an academic conference that could be broadcast by telephone, and wondered, "Why not send images, too? It could be called 'radio telephotography!'" Otlet also saw gramophones as a way to archive and reproduce spoken information. "We recently found a text written in 1907, in which he talks about mobile telephones," Gillen says, as he gingerly packs away Otlet's fragile original outlines.
Radio, at the time a new medium, was especially fascinating for Otlet because of its ability to transmit information wirelessly across long distances and to reach an unlimited number of receivers. For him, it was one step toward fulfilling the dream he formulated in 1934 for a "universal network that would allow the unrestricted dissemination of knowledge."
Anyone sitting at home "in an armchair," Otlet suggested, would be able to access the current state of global knowledge. Developments anywhere in the world could be recorded as soon as they happened, "in this way becoming a flexible image of the world, its mind, its true duplicate." Otlet described this as a "mechanical, collective brain."
A Loss of Funding and the Nazi Invasion Despite these visionary ideas, Otlet's Mundaneum suffered a harsh setback in 1934 when it was forced to close after its financial backers in the Belgian government lost interest in the project. When the Nazis marched into Brussels in 1940, they removed the collection from the "Palais Mondial" in the city's center and exhibited Nazi artwork there instead.
Otlet's vision of peace through knowledge had failed and he died in 1944, impoverished and bitter. It wasn't until 1968 that American researcher W. Boyd Rayward discovered parts of the collection. Rayward researched further, eventually managing to reopen the Mundaneum in 1998, on a somewhat smaller scale and located in the provincial town of Mons, about 30 kilometers (19 miles) outside of Brussels. Here, archivist Gillen and his colleagues are still sorting through masses of documents that amount to six kilometers (four miles) of archival material.
More than 60 years after his death, many of Otlet's ideas have become reality, and researchers and Internet experts are taking an interest in his thoughts on the "mechanical brain." Otlet's conception of a dynamic body of global knowledge, one which requires constant additions and is shaped collectively, bears clear similarities to the concept behind the online encyclopedia Wikipedia. Similarly, Otlet had thoughts on how to incorporate into his networked catalogue of knowledge different annotations that would correct mistakes or reveal contradictions.
Charles van den Heuvel at the Royal Netherlands Academy of Arts and Sciences, though, warns against warns against such comparisons. According to van den Heuvel's interpretation, Otlet was proposing a system in which knowledge would be laid out hierarchically; only a small group of scholars would organize the information, and changes and annotations would not be blended into existing information, as Wikipedia does, but would complement them.
A Semantic Network? Otlet's proposed network far surpassed the World Wide Web with its hypertext structure. Otlet didn't just want to connect various pieces of data with one another, he also wanted the links themselves to carry meaning. Many experts agree that Otlet's idea demonstrates many parallels to the concept of a "semantic network," which aims to make it possible for computers to utilize the actual meaning of data, allowing them to interpret information and process it automatically. Projects attempting to create a semantic network could benefit from a look at Otlet's ideas and at his thoughts on hierarchy and centralization in this context, van den Heuvel suggests. The staff at the Mundaneum in Mons is currently digitalizing Otlet's work, in order to make it available online. This process may take quite a long time, Gillen warns, but when it's done Otlet's vision will finally come true -- his collection of knowledge will be available to the world, paperless and open to all.

- This French film (with English and German audio tracks)
about Paul Otlet, a Belgian Utopian little known in America. Otlet invented an international classification
scheme called Universal Decimal Classification used for books, photographs and other documents. He invented
microfilm. He invented the ubiquitous index card catalog used in most libraries. But as he says in the film,
"I think in terms of the universal" and his ambitions were much larger. Otlet began organizing
existing international organizations into one grand inter-organization -- the Union of International
Organizations -- which inspired the League of Nations. His one failure was to build an ultimate World City
Europe, but it was not for a lack of trying.
But his most amazing invention (in retrospect) was his invention of hypertext, multi-media, and the web. He didn't use these words of course. He called it the International Network for Universal Documentation. In his 1934 "Treatise of Documentation" or "The book on the book" he lays it out:
Before our very eyes an immense machinery for intellectual work is being constructed. This machinery will serve as a veritable mechanical and collective brain. A universal publication system condensing all of the fragmentary and individual data and kept constantly up to date must be assembled for each branch of the sciences and other activities. This network must link production centers distributors and users. Any person with data to be made known or propositions to present or defend will be able to do so. Or with a minimum of effort and a guarantee of quality safety will be able to obtain any information.
His concept of hyperlinking is illustrated in the film in this YouTube clip from this film:
Otlet outlined these grand visions of easily accessible knowledge and interconnected data many decades
Vannevar Bush and Ted Nelson first articulated them. And more importantly, he actually
built an analog hypertext system. As this really amazing film makes clear, he collected and cataloged as
of the world's bibliographic knowledge as he could and then cross-indexed it. Rows and rows of card
At his peak he had 17 million index cards, and a system of search and retrieval.
Later in the same monograph Otlet writes, "Phonographs, radio, television, telephone -- these instruments taken as substitutes for the book will in fact become the new book, the most powerful work for the diffusion of human thoughts. This will be the radiated library, and the televised book."
The universal book was a part of the universal city, which was a part of the universal repository of all human knowledge, or what he called the Mundaneum. This was to contain, "All books, all articles, all memories, all published information. These would become chapters, sections, lines of a single and immense book, the book of universal science. It is this one book made up of individual books that must be made available to all."
Still his vision expanded. "This connection would be unaffected by distance ... and would become an annex to the brain, a sort of appended exodermic organ." Information architect Alex Wright calls Otlet our "forgotten forefather." He offers a great closing quote from Otlet:
Everything in the universe, and everything of man, would be registered at a distance as it was produced. In this way a moving image of the world will be established, a true mirror of his memory. From a distance, everyone will be able to read text, enlarged and limited to the desired subject, projected on an individual screen. In this way, everyone from his armchair will be able to contemplate creation, as a whole or in certain of its parts.
Otlet's early universalism was part of the reason he became forgotten and obscure. When the Nazis
Belgium in WWII they were intensely skeptical of his pacifism and internationalism. They destroyed his
archive. Because he wrote in French, and none of his major works have yet been translated into English, his
work was never part of the standard English history of the web.
This short film will help to change that. A shorter documentary in French and English by his biographer, W. Boyd Raward, are available for free streaming on Open Source Movies, gives a few additional details of how his system worked, but this story is incomplete.
