Bibliographic control is one of the few internationally highly standardized activities. The generally accepted IFLA Library Reference Model (IFLA LRM) has influenced the modification of numerous ...other standards in the field of bibliographic control. In this context, also on UNIMARC and ISBD. Moreover, at the IFLA WLIC 2022 Congress, the working group for the revision of international cataloguing principles announced that it was analyzing the introduction of the term “work with entities”. In the COBISS system, developments in the field of bibliographic control and standards related to it are closely monitored. The transition to the new millennium shed a new light on the organization of bibliographic information, placing in the focus of interest authority data as the basic building block of a new approach to managing the sources of the bibliographic universe. Therefore, first of all, the state of authority data in the COBISS.net network should be analyzed, which can serve as a starting point for development and cooperation between the member countries of the COBISS.net network also on this field.
Various studies have shown that low data quality in bibliographic and authority records is one of the main obstacles in data management. In order to evaluate and improve data quality in the Slovenian ...union bibliographic database (COBIB.SI), a pragmatic dimension-based data quality measurement and evaluation case study was carried out in 2019. The article presents the set-up and application of a methodological framework that was used for the definition and measurement of bibliographic and authority records quality in COBIB.SI. The results of the case study and the framework's applicability in data quality measurement and evaluation, as well as in data profiling that would benefit further development of COBISS + catalog, are also discussed.
In this paper, the results of an analysis of the data quality performed within quality control of daily bibliographic records production in the period from 2015 to 2020 are presented. The sample ...included 13,478 bibliographic records with associated authority records. The analysis is based on the data quality dimensions that were attributed to the recorded errors of the reviewed bibliographic and normative records. Also, the individual errors in the context of specific data elements are presented. Furthermore, the results include an indicative quality score of records in terms of the number of messages sent to cataloguers and the performance of the monitoring method in terms of the proportion of records corrected. According to our estimations, some 70% of the records reviewed were good or good enough and the response rate of cataloguers was relatively high. In the discussion, problems with some data elements were highlighted and it was stressed how important it is to keep up to date with changes in the Slovenian cataloguing practice.

As one of the segments of data quality analysis, theoretical and methodological approaches towards measuring the quality of data in bibliographic and authority records are presented. On the basis of ...professional literature review, the paper focuses on metrics, methods of measurement and results analysis. Based on profiling the data set acquired by analyzing recommendations given to librarians within quality control of daily bibliographic records production in COBIB.SI in 2015–2018, the case study was conducted where the quality of data within selected data elements used in facet navigation and in the display of search results lists in COBISS+ was measured. This case study shows the possibility of metrics design, which could be more applicable if compared with the existing counting errors approach. At the same time the case study reveals a set of data elements that have had low value in cataloguing practices so far.
