Implementation of authority control in the Cobiss.SI library information system, Slovenia

Describes a process of gradual implementation of authority control in the COBISS library information system in Slovenia (COBISS.SI). The CONOR.SI initial authority database contained, at the time of its implementation, over 24,000 authority records for personal authors, mostly Slovenian, from publishing production of the last few years. It was created automatically based on personal bibliographies of Slovenian researchers and the Slovenian national bibliography for monographs in COBISS.SI. Also describes: major conceptual issues related to the entire implementation logic of authority control; the upgrading of software for shared cataloguing required by the implementation of authority control; and the implementation process itself. Presents some experiences related to cataloguing with authority control within COBISS.SI together with plans on the subsequent implementation of authority control for other types of headings.
