Knowledge Organization (ISSN 0943-7444) is the official bi-monthly journal of ISKO. It was founded in 1973 by Dr. Ingetraut Dahlberg, the first President of ISKO, with a consulting board of editors representing the world's regions, the special classification fields, and the subject areas involved. The journal began publication in 1974 with the title International Classification; in 1989, it became the official organ of ISKO; and in 1993 (Volume 20), the title was changed to its present form. From 1974 to 1980 it was published by K. G. Saur Verlag of München; from 1981 to 1997 by Indeks Verlag of Frankfurt; and since 1998 by Ergon Verlag of Würzburg.

The contents of the journal are indexed and abstracted in Social Sciences Citation Index, Web of Science, Information Science Abstracts, INSPEC, Library and Information Science Abstracts (LISA), Library, Information Science & Technology Abstracts (EBSCO), Library Literature and Information Science (Wilson), PASCAL, Referativnyi Zhurnal Informatika, and Sociological Abstracts. ISI impact factor for 2014 was 0.448, and corresponding 5-year impact factor was 0.485.
