ISKO

What ISKO does

ISKO (International Society for Knowledge Organization) is a private, membership-based international scholarly society founded in 1989 in Germany and re-incorporated in Toronto, Canada in 2020. It serves approximately 600 members across 11 regional chapters spanning Brazil, Canada/US, China, France, DACH, Italy, Maghreb, Poland, Iberia, and the UK, drawing professionals from information science, library studies, philosophy, linguistics, computer science, and specialized domains such as health informatics. ISKO operates as a learned society rather than a commercial enterprise, with a Board of Directors, Scientific and Technical Advisory Council (STAC), and editorial boards governing its publications and events.

The society's core product portfolio centers on scholarly publishing and community platforms. Its flagship is the Knowledge Organization journal (JIF 0.6 in 2023), published eight times per year and transitioned to IMR Press in Hong Kong from 2025 in digital-only, open-access format. Complementary offerings include the freely available ISKO Encyclopedia of Knowledge Organization (IEKO), the Advances in Knowledge Organization (AKO) peer-reviewed proceedings series, the KO Literature Database (records from 1988 onward), monograph and textbook series, the ISKO-L electronic mailing list, and biennial international conferences rotating across member regions (most recently Wuhan 2024, scheduled São Paulo 2026).

ISKO's revenue model is subscription-driven and diversified across individual, student, retired, and institutional membership tiers priced in CAD (CAD 30-200/year, with developing-country discounts), supplemented by article processing charges (APCs) for the open-access journal, conference registration fees, and publication sales through Nomos eLibrary and IMR Press. Membership is processed through regional chapters, which retain a portion of dues and remit the remainder to the international secretariat. The society maintains cooperative relationships with UNESCO, the European Commission, ISO (including TC37/SC3 on terminology), IFLA, DCMI, NKOS, and ASIS&T SIG/CR, reinforcing its standards and metadata ecosystem positioning.

Core offering

ISKO is a membership-based international scholarly society that promotes research, development, and application of knowledge organization systems. It sells annual memberships (individual, student, retired, institutional tiers) that grant access to the Knowledge Organization journal (published eight times per year, open-access), the ISKO Encyclopedia of Knowledge Organization (IEKO), conference proceedings, and regional chapter activities. The society also generates revenue through article processing charges, conference registration fees, and sales of monographs and proceedings volumes.

Product overview

ISKO (International Society for Knowledge Organization) is a premier international scholarly society rather than a technology product company. Its offerings consist of knowledge organization publications and community platforms: the Knowledge Organization (KO) Journal published eight times annually; the ISKO Encyclopedia of Knowledge Organization (IEKO) as an open-access online resource; the Advances in Knowledge Organization (AKO) series containing peer-reviewed conference proceedings; the KO Literature Database for research; Textbooks for Knowledge Organization monographs; regional conference programs through its international chapters; and the ISKO-L mailing list community platform. These publications and resources serve researchers and professionals in library science, information science, philosophy, linguistics, and computer science rather than functioning as a commercial software product.

Expansion highlights5 records

Direct peers

• ASIS&T (Association for Information Science and Technology): ASIS&T is the leading generalist scholarly society for information science and technology. ISKO has a direct partnership with ASIS&T's SIG/CR (Classification Research), making them closely aligned in member base, conference activities, and journal publishing in overlapping subfields.
• DCMI (Dublin Core Metadata Initiative): DCMI is an organization advancing interoperable metadata standards, with a strong focus on knowledge organization systems. ISKO has established mutual cooperation with DCMI, and the two organizations serve overlapping communities of metadata and classification researchers.
• NKOS (Networked Knowledge Organization Systems/Services): NKOS is a network focused on networked KOS and semantic web applications. ISKO maintains mutual cooperation with NKOS, and both target the same intersection of knowledge organization, ontologies, and applied metadata research.
• SLA (Special Libraries Association): SLA is a global organization for information professionals in specialized settings. It shares with ISKO a focus on knowledge organization, taxonomy, and classification practices used by working information professionals.
• ALISE (Association for Library and Information Science Education): ALISE represents educators in library and information science. Its member base and conference programming overlap directly with ISKO's academic audience, particularly in classification, indexing, and knowledge organization pedagogy.

Broad incumbents

• IFLA (International Federation of Library Associations and Institutions): IFLA is a much larger international body representing library associations worldwide. ISKO cooperates with IFLA's Section on Subject Analysis and Access, and the two serve overlapping library and information science constituencies with ISKO as a more specialized niche player.
• ALA (American Library Association): ALA is the largest library association in the United States, with thousands of members. ISKO overlaps with ALA in classification and cataloging interests but operates as a much more specialized international scholarly society.
• ACM (Association for Computing Machinery): ACM is a much larger computing society that includes significant work on ontologies, knowledge representation, and the Semantic Web. ISKO's computer science members often publish in ACM venues, making it an adjacent incumbent in a broader field.
• IEEE Computer Society: IEEE Computer Society covers computing research including knowledge-based systems, ontologies, and information retrieval. It is a far larger incumbent serving overlapping technical communities, particularly in computer science applications of knowledge organization.

Regional players

• ICA (International Council on Archives): ICA is an international professional body focused on archives and records management. It overlaps with ISKO in archival description, classification standards, and authority control, but its primary membership is archivists rather than knowledge organization researchers.
