I was very surprised to read about Paul Otlet, his work, and his accurate vision for how information would be organized in the future. So many of his ideas laid the foundation for what became Information Science, the internet, the faceted search, and linked data. It is astonishing that Otlet’s vision, which marries “the determinism of facets with the relativism of social networks”, continues to unfold. Dewey and Ranganathan are regarded as “founding fathers” of Information Science. The readings rightfully recognize Otlet as having just as great an impact.
