Abstract
The objective of this case study is, on the example of Knowledge organization (KO) subject area, to find out how big volume of this literature is really open accessible, and to analyse and evaluate individual forms of this accessibility, from legal to illegal. The case study is based on extensive bibliographic database of literature from this subject area published worldwide, mainly in last 30 years.
The result of basic information retrieval was processed within research project NAKI -- Knowledge base for subject area of knowledge organization (DF13P01OVV013, Ministry of Culture of CZ). Covered literature concerns, in main part, the Information science field, but in accord with current approach to KO hits associate disciplines like Computer science, Linguistics, Semantics, and others.
Added data about accessibility, particularly electronic, were completed using selected resources. The accessibility of literature is evaluated by bibliometric method, individual forms of electronic accessibility, particularly open accessibility (online free publications, repositories and websites with preprints and postprints, illegal open access and others), are qualitative interpreted.
Specific attention is devoted to open access to articles from selected commercial journals in form of preprints, postprints or publisher's copies. The analysis concerns significant journals of KO subject area.
