This is the official website for ISKO – the premier international scholarly society devoted to the theory and practice of knowledge organization, bringing together professionals from different disciplines such as information science, philosophy, linguistics, and computer science, as well as special domains such as health informatics. ISKO's world-wide reach is supported through its regional Chapters.
ISKO hosts an international conference in even-numbered years. It last met in Wuhan, China, in March of 2024 and will meet again in 2026 in São Paulo, Brazil. Proceedings of international conferences are listed here. In odd-numbered years most of ISKO's regional chapters host conferences; many of these are multilingual.
ISKO publishes the journal Knowledge Organization eight times a year. ISKO also is publishing an online encyclopedia of knowledge organization. We have provided a database of KO literature and link to a repository of KO documents, to BARTOC KO registry and to other organizations of interest to KO scholars.
