The article is a short overview of the development and changes in cataloguing practice in Slovenian libraries from World War II to the present day, with special attention paid to the role and duties of the principal catalogue editor and the National Cataloguing Committee, revealing future actions and trends in the development of the national cataloguing codes.
A library chooses its cataloguing practice, depending on the environment where it operates. Some experience with and dilemmas about the use of the COMARC format are described as seen by cataloguers in a public library while solving their everyday practical cataloguing problems.
The article describes the process of library automation in the Bulgarian National Library and the conversion of the records in their databases into the COMARC format and lists the reasons why COBISS software was chosen by the National Library of Bulgaria and other Bulgarian libraries. It also mentions the need to expand the COMARC format due to countries with different cataloguing practices participating in the COBISS.Net project.
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.
Resource Description and Access (RDA), the successor to the Anglo-American Cataloging Rules (AACR), has had a significant impact on both bibliographic and authority data as they are represented in Machine-Readable Cataloging records in MARC 21. A brief history of the develoment of RDA is outlined. Since 2006, OCLC has kept up with some fifteen MARC 21 Bibliographic, Authority, and Holdings Updates through a total of nine OCLC-MARC Updates.
