My researches focuses on the relationship between quality management in library and bibliographic description. One of the central, topical issues of Hungarian and international library sciences concerns the full, high quality implementation of the bibliographic description of traditional and electronic documentary assets and retrospective catalogue conversion based on international and national standards and policies. Initiatives aiming at the fulfilment of this objective confront problems relating to the harmonisation of heterogeneous sources, data exchange formats and regulations. My research applies the premise of organisational self-assessment and a process oriented approach to quality to examine innovative methods serving the assessment and evaluation of bibliographic description processes, instruments that support process regulation, and the IT infrastructure supporting the quality improvement activities; this is used to review possibilities for improving bibliographic records created in the course of description and bibliographical services built on these.
