    Abstract
    In the post-war period before computers were readily available, urgent demand for scientific and industrial develop-ment stimulated research and development (R&D) that led to the birth of the information retrieval thesaurus. This article traces the early history, speciation and progressive improvement of the thesaurus to reach the state now conveyed by guidelines in inter-national and national standards. Despite doubts about the effec-tiveness of the thesaurus throughout this period, and notwith-standing the dominance of Google and other search engines in the information retrieval (IR) scene today, the thesaurus still plays a complementary part in the organization of knowledge and in-formation resources. Success today depends on interoperability, and is opening up opportunities in linked data applications. At the same time, the IR demand from workers in the knowledge society drives interest in hybrid forms of knowledge organization system (KOS) that may pool the genes of thesauri with those of ontologies and classification schemes.

    Abstract
    At the time when the Institute of Information Scientists was launched, well established principles of classification, especially faceted classification, provided an excellent springboard for developments in knowledge organization thereafter. The principles of thesaurus construction and use were worked out during the first two decades of the Institute's existence. Up until the end of the 1980s, most practical systems to exploit any of these vocabularies were held on cards, some of them highly ingenious. The subsequent arrival of the desktop computer, soon followed by the growth of networks providing access to an almost unimaginable quantity and variety of resources, has stimulated evolution of the knowledge organization schemes to exploit the technology available. Anecdotes of events and practical applications of controlled vocabularies illustrate this account of developments over the period.

    Abstract
    This entry presents an overview of the standards for different types of knowledge organization system (KOS). Their development history and the principles within them are described. Standards for thesauri receive most attention, since other types of KOS are less standardized. The arrival of the Internet, enabling simultaneous access to multiple disparate systems and resources, caused a major reorientation of standardization efforts in the last decade, towards interoperability goals. Current initiatives address two main needs: interoperability between KOSs, and data exchange between one vocabulary application and another. The prospects for bringing the standards together are discussed.

    Abstract
    The information retrieval thesaurus emerged in the 1950s, settled down to a more-or-less standard format in the 1970s and has continued to evolve marginally since then. Throughout its whole lifetime, doubts have been expressed about its efficacy with emphasis latterly on cost-effectiveness. Prolonged testing of different styles of index language in the 1970s failed to settle the doubts. The arena occupied by the debate has moved from small isolated databases in the post-war era to diverse situations nowadays with the whole Internet at one extreme and small in-house collections at the other. Sophisticated statistical techniques now dominate the retrieval landscape on the Internet but leave opportunities for the thesaurus and other knowledge organization techniques in niches such as image libraries and corporate intranets. The promise of an ontology-driven semantic web with linked data resources opens another opportunity. Thus much scope remains for research to establish the usefulness of the thesaurus in these places and to inspire its continuing evolution.
