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.
A set of dimensions was developed for the purposes of quality analysis of data of bibliographic and authority records. The dimensions are qualitative descriptions of the types of data required in records. The set was developed by literature review and typology of errors, prepared by analyzing the recommendations given to librarians within quality control of daily bibliographic records production in COBIB.SI in 2017. The final set consists of 11 dimensions; it includes different data requirements within the following two basic categories of dimensions: quality of data value and quality of data representation.
COBISS is a synonym for autonomous library information systems, used in Slovenia and in the countries of the South-Western Balkans for over 20 years. With the aim of faster exchange of bibliographic records in the region, these countries signed an agreement on the establishment of the COBISS.Net network in 2003.
Library catalogues allow users searching of library materials in different ways. To achieve successful and efficient searching, bibliographic and authority records should be created according to cataloguing rules, besides perfect and accurate records are required. That is why, cataloguers are responsible for an adequate quality of records and the quality control should be regularly examined.
