The Library is a sphere of multidimensional information area at the same time abstract and invisible and characterized fundamentally by semantics and space. Semantic relationships between the data constitute the structure of the space around attributes such as metadata, classifications or thesaurus. From the point of view of users, the library information system is an invisible and non-transparent project, while from the point of view of the system, the taxonomic organization is essential, even vital. We propose to show in this context how information visualization transforms invisible structured data and their semantic relationships in a readable display. This process derived from Gestalt theory reveals the conceptual structures of the documentary system for research and information processing based on the classificatory design and mapping, we show it through two applications on both sides of the Atlantic. Two instrumented devices documentary mediation initiated concomitantly on both sides of the Atlantic effectively illustrate this approach. In the United States, the Seattle Library has set up a project ("Making the Invisible Visible") with 6 plasma screens behind the main librarians' desk feature real-time calculated animation visualizations by the circulation of items catalogued according to the Dewey decimal system going in and out of the library's collection. This flow of information which can be calculated mathematically, analyzed statistically and represented visually transforms the library into a data exchange center. Visual…Catalog in France, a visualization device first developed at the University Paris 8, then to the library Artois, connects classes, references and conceptual elements Rameau to view the conceptual model and promote a systemic understanding.
