The paper introduces and discusses the concept of the Knowledge Organization System (KOS), which has replaced the terms ‘indexing languages’ and ‘information retrieval languages’ in the library and information science. The modern concept of KOS primarily includes classifications, thesauri, semantic networks and ontologies. The paper offers an overview of various KOS typologies, including those reflected in regulatory documents and used in KOS collections, registers and repositories. Various features used in the identification of KOS types are discussed. Spectral approaches to KOS classification based on the idea of semantic complexity (seman-tic power) of KOS are considered. A practical typology of KOS is proposed.
