The papers in this e-book constitute a selection of those delivered at the first national conference of the United Kingdom chapter of the International Society for Knowledge Organization (ISKO). The conference, "Content architecture: exploiting and managing diverse resources", was held at University College London in June 2009. ISKO UK provides a natural home, not only for practitioners and academics in conventional LIS, but also taxonomists, intranet managers, indexers and content managers; it has attracted an even wider audience to its events, with archivists, records managers, systems managers, computer scientists, and academics in a number of fields all being represented.
